    Late last week, Israel began a wave of attacks on Iran under the banner of Operation Rising Lion, with the stated goal of crippling the Islamic republic’s nuclear program and long-range strike capabilities. At the outset, Israel claimed Iran would soon be able to build nine nuclear weapons, a situation Israel regarded as completely unacceptable.

    Following Israeli strikes against Iranian nuclear facilities, and targeted assassinations of Iranian nuclear scientists and key members of the Iranian armed forces, Iran retaliated with a large barrage of ballistic missiles and drones against Tel Aviv and Jerusalem. The first wave consisted of some 200 ballistic missiles and 200 drones.

    The conflict continues to escalate, with population centres increasingly being targeted. Israel’s missile defence systems (including the vaunted Iron Dome) have so far staved off most of Iran’s attacks, but the future is uncertain.

    Ballistic missiles and how to stop them

    Iran possesses a large arsenal of ballistic missiles and long-range drones, alongside other long-range weapons such as cruise missiles. Ballistic missiles travel on a largely fixed path steered by gravity, while cruise missiles can adjust their course as they fly.

    Iran is approximately 1,000km from Israel, so the current strikes mostly involve what are classified as medium-range ballistic missiles, alongside long-range drones. It is not clear exactly what type of missile Iran has used in its latest strikes, but the country has several including the Fattah-1 and Emad.

    It is very difficult to defend against ballistic missiles. There is not much time between launch and impact, and they come down at very high speed. The longer the missile’s range, the faster and higher it flies.

    An incoming missile presents a small, fast-moving target – and defenders may have little time to react.

    Israel’s missile defence and the Iron Dome

    Israel possesses arguably one of the most effective, battle-tested air defence systems in service today. The system is often described in the media as the “Iron Dome”, but this is not quite correct.

    Israel’s defences have several layers, each designed to address threats coming from different ranges.

    Iron Dome is just one of these layers: a short range, anti-artillery defence system, designed to intercept short-range artillery shells and rockets.

    In essence, Iron Dome consists of a network of radar emitters, command and control facilities, and the interceptors (special surface-to-air missiles). The radar quickly detects incoming threats, the command and control elements decide which are most pressing, and the interceptors are sent to destroy the incoming shells or rockets.

    Ballistic defence systems

    The other layers of Israel’s defence system include David’s Sling, and the Arrow 2 and Arrow 3 interceptors. These are specifically designed to engage longer-range ballistic missiles, both within the atmosphere and at very high altitudes above it (known as exoatmospheric interception).

    Spectacular footage has been captured of what are likely exoatmospheric interceptions taking place during this latest conflict, demonstrating Israel’s capacity to engage longer-range missiles.

    The US military has comparable missile defence systems. The US Army has the Patriot PAC-3 (comparable to David’s Sling) and THAAD (comparable to Arrow 2), while the US Navy has the Aegis and the SM-3 (comparable to Arrow 3) and the SM-6 (comparable again to Arrow 2).

    The US deployed Aegis-equipped warships to support Israel’s defence against missile attacks in 2024, and appears to be preparing to do the same now.

    Iran possesses some air defence systems such as the Russian S300 which has some (very limited) ballistic missile defence capabilities, but only against shorter range (and thus slower) ballistic missiles. Further, Israel has been focusing on degrading Iran’s air defences, so it is not clear how many are still operational.

    Iran has been focusing on developing technology such as maneuverable warheads, which are harder to defend against. However, it is not clear whether these are yet operational and in Iranian service.

    Can missile defences last forever?

    Missile defences are finite. The defender is always limited by the number of interceptors it possesses.

    The attacker is also limited by the number of missiles it possesses. However, the defender must often assign multiple interceptors to each attacking missile, in case the first misses or otherwise fails.

    The attacker will plan for some losses to interceptors (or mechanical failures) and send what it determines to be enough missiles for at least some to penetrate the defences.

    When it comes to ballistic missiles, the advantage lies with the attacker. Ballistic missiles can carry large explosive payloads (or even nuclear warheads), so even a handful of missiles “leaking” past defensive systems can still wreak significant damage.

    What now?

    Israel’s missile defences are unlikely to stop working completely. However, as attacks deplete its stocks of interceptors, the system may become less effective.

    As the conflict continues, it may become a race to see who runs out of weapons first. Will it be Iran’s stocks of ballistic missiles and drones, or the interceptors and anti-air munitions of Israel, the US and any other supporters?

    It is impossible to say who would prevail in such a race of stockpile attrition. Some reports suggest Iran has fired approximately 1,000 ballistic missiles of an estimated 3,000. However, this still leaves it with an enormous stockpile to use, and it is unclear how fast Iran can make new missiles to replenish its resources.

    But we should hope it doesn’t come to that. Beyond the tit-for-tat exchange of missiles, the latest conflict between Israel and Iran risks escalating. If it is not resolved soon, and if the US is drawn into the conflict more directly, we may see broader conflict in the Middle East.

  • MIL-OSI Analysis: What is uranium enrichment and how is it used for nuclear bombs? A scientist explains

    Late last week, Israel targeted three of Iran’s key nuclear facilities – Natanz, Isfahan and Fordow, killing several Iranian nuclear scientists. The facilities are heavily fortified and largely underground, and there are conflicting reports of how much damage has been done.

    Natanz and Fordow are Iran’s uranium enrichment sites, and Isfahan provides the raw materials, so any damage to these sites would limit Iran’s ability to produce nuclear weapons.

    But what exactly is uranium enrichment and why does it raise concerns?

    To understand what it means to “enrich” uranium, you need to know a little about uranium isotopes and about splitting the atom in a nuclear fission reaction.

    What is an isotope?

    All matter is made of atoms, which in turn are made up of protons, neutrons and electrons. The number of protons is what gives atoms their chemical properties, setting apart the various chemical elements.

    Atoms have equal numbers of protons and electrons. Uranium has 92 protons, for example, while carbon has six. However, the same element can have different numbers of neutrons, forming versions of the element called isotopes.

    This hardly matters for chemical reactions, but their nuclear reactions can be wildly different.

    The difference between uranium-238 and uranium-235

    When we dig uranium out of the ground, 99.27% of it is uranium-238, which has 92 protons and 146 neutrons. Only 0.72% of it is uranium-235 with 92 protons and 143 neutrons (the remaining 0.01% are other isotopes).

    For nuclear power reactors or weapons, we need to change the isotope proportions. That’s because of the two main uranium isotopes, only uranium-235 can support a fission chain reaction: one neutron causes an atom to fission, which produces energy and some more neutrons, causing more fission, and so on.

    This chain reaction releases a tremendous amount of energy. In a nuclear weapon, the goal is to have this chain reaction occur in a fraction of a second, producing a nuclear explosion.

    In a civilian nuclear power plant, the chain reaction is controlled. Nuclear power plants currently produce 9% of the world’s power. Another vital civilian use of nuclear reactions is for producing isotopes used in nuclear medicine for the diagnosis and treatment of various diseases.

    What is uranium enrichment, then?

    To “enrich” uranium means taking the naturally found element and increasing the proportion of uranium-235 while removing uranium-238.

    There are a few ways to do this (including new inventions from Australia), but commercially, enrichment is currently done with a centrifuge. This is also the case in Iran’s facilities.

    Centrifuges exploit the fact that uranium-238 is about 1% heavier than uranium-235. They take uranium (in gas form) and use rotors to spin it at 50,000 to 70,000 rotations per minute, with the outer walls of the centrifuges moving at 400 to 500 metres per second.

    This works much like a salad spinner that throws water to the sides while the salad leaves stay in the centre. The heavier uranium-238 moves to the edges of the centrifuge, leaving the uranium-235 in the middle.

    This is only so effective, so the spinning process is done over and over again, building up the percentage of the uranium-235.

    Most civilian nuclear reactors use “low enriched uranium” that’s been enriched to between 3% and 5%. This means that 3–5% of the total uranium in the sample is now uranium-235. That’s enough to sustain a chain reaction and make electricity.

    What level of enrichment do nuclear weapons need?

    To get an explosive chain reaction, uranium-235 needs to be concentrated significantly more than the levels we use in nuclear reactors for making power or medicines.

    Technically, a nuclear weapon can be made with as little as 20% uranium-235 (known as “highly enriched uranium”), but the more the uranium is enriched, the smaller and lighter the weapon can be. Countries with nuclear weapons tend to use about 90% enriched, “weapons-grade” uranium.

    According to the International Atomic Energy Agency (IAEA), Iran has enriched large quantities of uranium to 60%. It’s actually easier to go from an enrichment of 60% to 90% than it is to get to that initial 60%. That’s because there’s less and less uranium-238 to get rid of.

    This is why Iran is considered to be at extreme risk of producing nuclear weapons, and why centrifuge technology for enrichment is kept secret.

    Ultimately, the exact same centrifuge technology that produces fuel for civilian reactors can be used to produce nuclear weapons.

    Inspectors from the IAEA monitor nuclear facilities worldwide to ensure countries are abiding by the rules set out in the global nuclear non-proliferation treaty. While Iran maintains it’s only enriching uranium for “peaceful purposes”, late last week the IAEA board ruled Iran was in breach of its obligations under the treaty.

  • MIL-OSI Analysis: Iran war: from the Middle East to America, history shows you cannot assassinate your way to peace

    Source: The Conversation – Global Perspectives – By Matt Fitzpatrick, Professor in International History, Flinders University

    In the late 1960s, the prevailing opinion among Israeli Shin Bet intelligence officers was that the key to defeating the Palestinian Liberation Organisation was to assassinate its then-leader Yasser Arafat.

    The elimination of Arafat, the Shin Bet commander Yehuda Arbel wrote in his diary, was “a precondition to finding a solution to the Palestinian problem.”

    For other, even more radical Israelis – such as the ultra-nationalist assassin Yigal Amir – the answer lay elsewhere. They sought the assassination of Israeli leaders such as Yitzak Rabin who wanted peace with the Palestinians.

    Despite Rabin’s long personal history as a famed and often ruthless military commander in the 1948 and 1967 Arab-Israeli Wars, Amir stalked and shot Rabin dead in 1995. He believed Rabin had betrayed Israel by signing the Oslo Accords peace deal with Arafat.

    It’s been 20 years since Arafat died as possibly the victim of polonium poisoning, and 30 years after the shooting of Rabin. Peace between Israelis and the Palestinians has never been further away.

    What Amnesty International and a United Nations Special Committee have called genocidal attacks on Palestinians in Gaza have spilled over into Israeli attacks on the prominent leaders of its enemies in Lebanon and, most recently, Iran.

    Since its attacks on Iran began on Friday, Israel has killed numerous military and intelligence leaders, including Iran’s intelligence chief, Mohammad Kazemi; the chief of the armed forces, Mohammad Bagheri; and the commander of the Islamic Revolutionary Guard Corps, Hossein Salami. At least nine Iranian nuclear scientists have also been killed.

    Israel’s Prime Minister Benjamin Netanyahu reportedly said:

    We got their chief intelligence officer and his deputy in Tehran.

    Iran, predictably, has responded with deadly missile attacks on Israel.

    Far from having solved the issue of Middle East peace, assassinations continue to pour oil on the flames.

    A long history of extra-judicial killings

    Israeli journalist Ronen Bergman’s book Rise and Kill First argues assassinations have long sat at the heart of Israeli politics.

    In the past 75 years, there have been more than 2,700 assassination operations undertaken by Israel. These have, in Bergman’s words, attempted to “stop history” and bypass “statesmanship and political discourse”.

    This normalisation of assassinations has been codified in the Israeli expression of “mowing the grass”. This is, as historian Nadim Rouhana has shown, a metaphor for a politics of constant assassination. Enemy “leadership and military facilities must regularly be hit in order to keep them weak.”

    The point is not to solve the underlying political questions at issue. Instead, this approach aims to sow fear, dissent and confusion among enemies.

    Thousands of assassination operations have not, however, proved sufficient to resolve the long-running conflict between Israel, its neighbours and the Palestinians. The tactic itself is surely overdue for retirement.

    Targeted assassinations elsewhere

    Israel has been far from alone in this strategy of assassination and killing.

    Former US President Barack Obama oversaw the extra-judicial killing of Osama Bin Laden, for instance.

    After what Amnesty International and Human Rights Watch denounced as a flawed trial, former US President George W. Bush welcomed the hanging of Iraqi leader Saddam Hussein as “an important milestone on Iraq’s course to becoming a democracy”.

    Current US President Donald Trump oversaw the assassination of Iran’s leader of clandestine military operations, Qassem Soleimani, in 2020.

    More recently, however, Trump appears to have baulked at granting Netanyahu permission to kill Iran’s Supreme Leader Ayatollah Ali Khamenei.

    And it’s worth noting the US Department of Justice last year brought charges against an Iranian man who said he’d been tasked with killing Trump.

    Elsewhere, in Vladimir Putin’s Russia, it’s common for senior political and media opponents to be shot in the streets. Frequently they also “fall” out of high windows, are killed in plane crashes or succumb to mystery “illnesses”.

    A poor record

    Extra-judicial killings, however, have a poor record as a mechanism for solving political problems.

    Cutting off the hydra’s head has generally led to its often immediate replacement by another equally or more ideologically committed person, as has already happened in Iran. Perhaps they too await the next round of “mowing the grass”.

    But as the latest Israeli strikes in Iran and elsewhere show, solving the underlying issue is rarely the point.

    In situations where finding a lasting negotiated settlement would mean painful concessions or strategic risks, assassinations prove simply too tempting. They circumvent the difficulties and complexities of diplomacy while avoiding the need to concede power or territory.

    As many have concluded, however, assassinations have never killed resistance. They have never killed the ideas and experiences that give birth to resistance in the first place.

    Nor have they offered lasting security to those who have ordered the lethal strike.

    Enduring security requires that, at some point, someone grasp the nettle and look to the underlying issues.

    The alternative is the continuation of the brutal pattern of strike and counter-strike for generations to come.

  • MIL-OSI Analysis: The Middle East is a major flight hub. How do airlines keep passengers safe during conflict?

    The Middle East is a region of intense beauty and ancient kingdoms. It has also repeatedly endured periods of geopolitical instability over many centuries.

    Today, geopolitical, socio-political and religious tensions persist. The world is currently watching as longstanding regional tensions come to a head in the shocking and escalating conflict between Israel and Iran.

    The global airline industry takes a special interest in how such tensions play out. This airspace is a crucial corridor linking Europe, Asia and Africa.

    The Middle East is now home to several of the world’s largest international airlines: Emirates, Qatar Airways and Etihad Airways. These airlines’ home bases – Dubai, Doha and Abu Dhabi, respectively – have become pivotal hubs in international aviation.

    Keeping passengers safe will be all airlines’ highest priority. What could an escalating conflict mean for both the airlines and the travelling public?

    Safety first

    History shows that the civil airline industry and military conflict do not mix. On July 3 1988, the USS Vincennes, a US navy warship, fired two surface-to-air missiles and shot down Iran Air Flight 655, an international passenger service over the Persian Gulf.

    More recently, on July 17 2014, Malaysian Airlines Flight MH17 was shot down over eastern Ukraine as the battle between Ukrainian forces and pro-Russian separatists continued.

    Understandably, global airlines are very risk-averse when it comes to military conflict. The International Civil Aviation Organization requires airlines to implement and maintain a Safety Management System (SMS).

    One of the main concerns – known as “pillars” – of the SMS is “safety risk management”. This includes the processes to identify hazards, assess risks and implement risk mitigation strategies.

    The risk-management departments of airlines transiting the Middle East region will have been working hard on these strategies.

    Headquartered in Montreal, Canada, the International Civil Aviation Organization has strict requirements and protocols to keep passengers safe.

    Route recalculation

    The most immediate and obvious evidence of such strategies being put in place are changes to aircraft routing, either by cancelling or suspending flights or making changes to the flight plans. This is to ensure aircraft avoid the airspace where military conflicts are flaring.

    At the time of writing, a quick look at flight tracking website Flightradar24 shows global aircraft traffic avoiding the airspace of Iran, Iraq, Syria, Israel, Jordan, Palestine and Lebanon. The airspace over Ukraine is also devoid of air traffic.

    Rerouting, however, creates its own challenges. Condensing the path of the traffic into smaller, more congested areas can push aircraft into and over areas that are not necessarily equipped to deal with such a large increase in traffic.

    Having more aircraft in a smaller amount of available safe airspace creates challenges for air traffic control services and the pilots operating the aircraft.

    More time and fuel

    Avoiding areas of conflict is one of the most visible forms of airline risk management. This may add time to the length of a planned flight, leading to higher fuel consumption and other logistical challenges. This will add to the airlines’ operating costs.

    There will be no impact on the cost of tickets already purchased. But if the instability in the region continues, we may see airline ticket prices increase.

    It is not just the avoidance of airspace in the region that could place upward pressure on the cost of flying. Airliners run on Jet-A1 fuel, produced from oil.

    If Iran closes the Strait of Hormuz, the “world’s most important oil transit chokepoint”, this could see the cost of oil, and in turn Jet-A1, significantly increase. Increasing fuel costs will be passed on the paying passenger. However, some experts believe such a move is unlikely.

    A major hub

    The major aviation hubs in the Middle East provide increased global connectivity, enabling passengers to travel seamlessly between continents.

    Increased regional instability has the potential to disrupt this global connectivity. In the event of a prolonged conflict, airlines operating in and around the region may find they have increased insurance costs. Such costs would eventually find their way passed on to consumers through higher ticket prices.

    Passenger confidence

    Across the globe, airlines and governments are issuing travel advisories and warnings. The onus is on the travelling public to stay informed about changes to flight status, and potential delays.

    Such warnings and advisories can lead to a drop in passenger confidence, which may then lead to a drop in bookings both into and onwards from the region.

    Until the increase in instability in the Middle East, global airline passenger traffic numbers were larger than pre-pandemic figures. Strong growth had been predicted in the coming decades.

    Anything that results in falling passenger confidence could negatively impact these figures, leading to slowed growth and affecting airline profitability.

    Despite high-profile disasters, aviation remains the safest form of transport. As airlines deal with these challenges they will constantly work to keep flights safe and to win back passenger confidence in this unpredictable situation.

  • MIL-OSI Analysis: Dopamine can make it hard to put down our phone or abandon the online shopping cart. Here’s why

    Source: The Conversation – Global Perspectives – By Anastasia Hronis, Clinical Psychologist, University of Technology Sydney

    Vardan Papikyan/Unsplash

    Ever find yourself unable to stop scrolling through your phone, chasing that next funny video or interesting post?

    Or maybe you’ve felt a rush of excitement when you achieve a goal, eat a delicious meal, or fill your online shopping cart.

    Why do some experiences feel so rewarding, while others leave us feeling flat? Well, dopamine might be responsible for that. Here’s what it does in our brains and bodies.

    It’s a chemical messenger

    Dopamine is a neurotransmitter – a chemical messenger that facilitates communication between the brain and the central nervous system. It sends messages between different parts of your nervous system, helping your body and brain coordinate everything from your movement to your mood.

    Dopamine is most known for its role in short-term pleasure, and the boost we get from things such as eating tasty foods, drinking alcohol, scrolling social media or falling in love.

    Dopamine also assists with learning, maintaining focus and attention, and helps us store memories.

    It even plays a role in kidney function by regulating the levels of salt and water we excrete.

    Conversely, low levels of dopamine have been linked to neurodegenerative disorders such as Parkinson’s disease.

    How dopamine motivates us to pursue pleasure

    Dopamine is not just active when we do pleasurable things. It’s active beforehand and it drives us to pursue pleasure.

    Say I go to a cafe and decide to buy a doughnut. When I bite into the doughnut, it tastes fantastic. Dopamine surges and I experience pleasure.

    The next time I walk past the cafe, dopamine is already active. It remembers the doughnut I had last time and how delicious it was. Dopamine drives me to walk back into the cafe, purchase another doughnut and eat it.

    Dopamine drives us to do things that felt good last time.

    From an evolutionary perspective, dopamine was incredibly important and it ensured survival of the species. It motivated behaviours such as hunting and foraging for food. It reinforced the pursuit of finding shelter and safety and keeping away from predators. And it motivated people to seek out mates and to reproduce.

    However, modern technology has amplified the effects of dopamine, leading to negative consequences. Activities such as excessive social media use, gambling, consuming alcohol, drug use, sex, pornography and gaming can stimulate dopamine release, creating cycles of addiction and compulsive behaviours.

    Our dopamine levels can vary

    Our brain is constantly releasing small amounts of dopamine at a “baseline” rate. This is because dopamine is crucial to the functioning of our brain and body, irrespective of pleasure.

    Everyone has a different baseline, influenced by genetic factors such as our DRD2 dopamine receptor genes. Some people produce and metabolise dopamine faster than other people. Our baseline levels can also be influenced by sleep, nutrition and stress in our lives.

    Given we all have a baseline of dopamine, our experience of pleasure at any given time is relative to our baseline rate and relative to what has come before.

    If I play games on my phone all morning and get a dopamine release from that, then I eat something tasty for morning tea, I may not experience the same level of fulfilment or enjoyment that I would have had I not played those games.

    The brain works hard to regulate itself and it won’t allow us to be in a constant state of dopamine “highs”. This means we can build a tolerance to certain exciting activities if we seek them out too much, as the brain wants to avoid being in a state of constant dopamine “highs”.

    Healthy ways to get a dopamine boost

    Thankfully, there are healthy, non-addictive ways to boost your dopamine levels.

    Exercise is one of the most effective methods for boosting dopamine naturally. Physical activities such as walking, running, cycling, or even dancing can trigger the release of dopamine, leading to improved mood and greater motivation.

    Running can also give you a dopamine boost.
    Leandro Boogalu/Pexels

    Research has shown listening to music you enjoy makes your brain release more dopamine, giving you a pleasurable experience.

    And of course, spending time with people whose company we enjoy is another great way to activate dopamine.

    Incorporating these habits into daily life can support your brain’s natural dopamine production and help you enjoy lasting improvements in motivation, mood and overall health.

  • MIL-OSI Analysis: Jaws at 50: how two musical notes terrified an entire generation

    Source: The Conversation – Global Perspectives – By Alison Cole, Composer and Lecturer in Screen Composition, Sydney Conservatorium of Music, University of Sydney

    Universal Pictures

    Our experience of the world often involves hearing our environment before seeing it. Whether it’s the sound of something moving through nearby water, or the rustling of vegetation, our fear of the unseen is rooted in our survival instincts as a species.

    Cinematic sound and music taps into these somewhat unsettling instincts – and this is exactly what director Steven Spielberg and composer John Williams achieved in the iconic 1975 thriller Jaws. The sound design and musical score work in tandem to confront the audience with a mysterious killer animal.

    In what is arguably the film’s most iconic scene, featuring beach swimmers’ legs flailing underwater, the shark remains largely unseen – yet the sound perfectly conveys the threat at large.

    Creating tension in a soundtrack

    Film composers aim to create soundscapes that will profoundly move and influence their audience. And they express these intentions through the use of musical elements such as rhythm, harmony, tempo, form, dynamics, melody and texture.

    In Jaws, the initial encounter with the shark opens innocently with the sound of an offshore buoy and its clanging bell. The scene is established both musically and atmospherically to evoke a sense of isolation for the two characters enjoying a late-night swim on an empty beach.

    But once we hear the the low strings, followed by the central two-note motif played on a tuba, we know something sinister is afoot.

    This compositional technique of alternating between two notes at an increasing speed has long been employed by composers, including by Antonín Dvořák in his 1893 work New World Symphony.

    John Williams reportedly used six basses, eight cellos, four trombones and a tuba to create the blend of low frequencies that would go on to define his entire Jaws score.

    The bass instruments emphasise the lower end of the musical frequency spectrum, evoking a dark timbre that conveys depth, power and intensity. String players can use various bowing techniques, such as staccato and marcato, to deliver dark and even menacing tones, especially in the lower registers.

    Meanwhile, there is a marked absence of tonality in the repeating E–F notes, played with increasing speed on the tuba. Coupled with the intensifying dynamics in the instrumental blend, this accelerating two-note motif signals the looming danger before we even see it – tapping into our instinctive fear of the unknown.

    The use of the two-note motif and lower-end orchestration characterises a composition style that aims to unsettle and disorientate the audience. Another example of this style can be heard in Bernard Herrmann’s car crash scene audio in North by Northwest (1959).

    Similarly, in Sergei Prokofiev’s Scythian Suite, the opening of the second movement (Dance of the Pagan Gods) uses an alternating D#–E motif.

    The elasticity of Williams’ motif allows the two notes to be played on different instruments throughout the soundtrack, exploring various timbral possibilities to induce a kaleidoscope of fear, panic and dread.

    The psychology behind our response

    What is it that makes the Jaws soundtrack so psychologically confronting, even without the visuals? Music scholars have various theories. Some suggest the two notes imitate the sound of human respiration, while others have proposed the theme evokes the heartbeat of a shark.

    Williams explained his approach in an interview with the Los Angeles Times:

    I fiddled around with the idea of creating something that was very … brainless […] Meaning something could be very repetitious, very visceral, and grab you in your gut, not in your brain. […] It could be something you could play very softly, which would indicate that the shark is far away when all you see is water. Brainless music that gets louder and gets closer to you, something is gonna swallow you up.

    Williams plays with the audience’s emotions throughout the film’s score, culminating in the scene Man Against Beast – a celebration of thematic development and heightened orchestration.

    The film’s iconic soundtrack has created a legacy that extends beyond the visual. And this suggests the score isn’t just a soundtrack – but a character in its own right.

    By using music to reveal what is hidden, Williams creates an intense emotional experience rife with anticipation and tension. The score’s two-note motif showcases his genius – and serves as a sonic shorthand that has kept a generation behind the breakers of every beach.

    Gilles Deleuze was one of the most original and imaginative thinkers of postwar France. A lifelong teacher, he spent most of his career at the University of Paris VIII, influencing generations of students but largely shunning the mantle of public intellectual.

    His complex, creative books mix philosophy, literature, film and politics – not to give clear answers, but to spark new ways of thinking.

    Postscript on the Societies of Control, published 35 years ago in the countercultural L’Autre Journal is Deleuze at his most accessible and prophetic.

    Written at a time when the Cold War was ending, computers were becoming more common, and the internet was beginning to connect institutions, the essay describes the emergence of a new kind of society – one not ruled by a single stern voice but by the soft hum of networks.

    How societies work

    Postscript was written as an update to the work of Deleuze’s contemporary Michel Foucault, who had died in 1984. Deleuze called it a “postscript” not just because of its brevity (it’s only around 2,300 words in English translation) but to highlight he wasn’t refuting Foucault, just building on his work.

    From the 18th to early 20th centuries, Foucault had argued, Western societies were “disciplinary societies”. Schools, factories, prisons and hospitals – institutions with walls, schedules, routines and clear expectations – moulded behaviour. People were trained, observed, tested and corrected as they passed from one institution to the next.

    But in the late 20th century, Deleuze saw something shifting. He thought the stodgy old disciplinary institutions were “in a generalized crisis” due to technological advances and a new form of capitalism that demanded more flexibility in workers and consumers.

    New systems of management and technology were starting to reshape people without sending them through traditional institutions. Deleuze wrote presciently, for example, that “perpetual training tends to replace the school, and continuous control to replace the examination”.

    In business, he saw a growing idea of “salary according to merit”, transforming work into “challenges, contests, and highly comic group sessions” – something much at odds with the old model of the standard wage and the assembly line. Traditional government institutions like hospitals and the classic factory were embracing the model of the corporation, driven always by a profit motive and the need for better human tools.

    To Deleuze, all this meant people were becoming more “free-floating” – they could be still playing socially useful roles but were being gently steered into them. This greater freedom, however, required a new system to keep everyone in line. He called this “modulation” to underline its dynamic, enveloping nature.

    Like nudging, but everywhere

    Deleuze described modulation as “a self-deforming cast that will continuously change from one moment to the other”. He meant that people were beginning to live in an environment where everything shape-shifts to encourage or discourage us in the right direction without explicitly putting up walls.

    A prime example of how modulation has since become commonplace is nudging – the use of psychological techniques, often subtle and data-driven, to shape people’s behaviour.

    Nudging didn’t really exist in 1990, but governments and tech companies use nudges all the time now. We’re nudged to eat healthier, buy, save, recycle, donate. Web sites use “dark patterns” – tricky designs that steer (or nudge) us toward certain choices. Social media feeds use algorithms to exclude us if we say the wrong thing. In fact, entire teams of behavioural scientists operate behind the scenes to manipulate many aspects of our lives.

    Nudges can be good and can save us from poor choices, but their newfound moral acceptability (sometimes called libertarian paternalism) is very much a clue that Deleuze’s control society has arrived.

    Control in your pocket

    Deleuze, who died in 1995, wrote Postscript before the advent of the smartphone, but he foresaw that an “electronic collar” would assume a central role in society. He envisaged a “computer that tracks each person’s position – licit or illicit – and effects a universal modulation.”

    Smartphones more than fit the bill. In the old disciplinary ways, they track where we go, what we search for, what we buy, how many steps we take, even how well we sleep. But if we apply Deleuze’s ideas to these phones, detailed surveillance is no longer their most important function. Our phones present and curate options.

    In effect, they shape how we see the world. When you scroll through news or social media, for instance, you’re reading about a version of the world built just for you, designed to keep you looking, clicking and reacting – and keep you very finely attuned to what is acceptable or dangerous behaviour.

    In Deleuze’s terms, this is pure modulation: not a forceful “No” but a softly spoken, “How about this?” Your phone doesn’t lock you in – it draws you in. It shapes what you see, rewards your cooperation, ignores your silence, and always keeps score. And it does this 24/7. You might unlock it hundreds of times a day. And each time it’s updated to guide your next move more precisely.

    At the same time our phones quietly turn us into a set of credentials useful for regulating physical access to workplaces, bank accounts, information: In the societies of control, writes Deleuze, “what is important is no longer either a signature or a number, but a code: the code is a password.”

    Data points not people?

    Deleuze warned that, in a control society: “Individuals have become ‘dividuals,’ and masses have become samples, data, markets, or ‘banks.’” A dividual to Deleuze is a person transformed into a set of data points and metrics.

    You are your credit rating, your search history, your likes and clicks – a different dataset to every institution. Such fragments are used to make decisions about you until they effectively replace you. In fact, for Deleuze a dividual has internalised this treatment and thinks of themselves as a net worth, a mortgage size, a car value – psychological anchors for control.

    He illustrates this point with healthcare, predicting a

    new medicine ‘without doctor or patient’ that singles out potential sick people and subjects at risk, which in no way attests to individuation.

    How many health decisions are now made for us collectively before we ever see a doctor? We should be grateful for advances in public health and epidemiology, but this has certainly impacted our individuality and how we are treated.

    Hard to detect

    An unsettling part of Deleuze’s perspective is that control doesn’t usually feel like control. It’s often dressed up as convenience, efficiency or progress. You set up internet-linked video cameras because then you can work from home. You agree to long terms and conditions because your banking app won’t work otherwise.

    One problem is there are no longer clear barriers we can rail against. As Deleuze said:

    In disciplinary societies one was always starting again (from school to the barracks, from the barracks to the factory), while in control societies one is never finished with anything.

    Control doesn’t always crush – it can enable. Digital networks bring real freedom, economic possibility, even joy. We move more easily – both mentally and geographically – than ever before. But while we move, it always inside a kind of invisible map shaped by capitalism.

    It’s no conspiracy because nobody has the whole map. So it’s difficult to work out exactly what action, if any, to take. As Deleuze concludes: “The coils of a serpent are even more complex than the burrows of a molehill.”

    So what can we do?

    Postscript doesn’t offer a political program beyond the sardonic comment that:

    Many young people strangely boast of being ‘motivated’ […] It’s up to them to discover what they’re being made to serve.

    There are ways to resist control. Some people demand more privacy or digital rights. Others opt out selectively – logging off, turning off, refusing to be nudged. Some look to art as a way of resisting its smooth grip. These acts – however small – may offer what Deleuze and his collaborator, the French psychiatrist and philosopher Félix Guattari, called lines of flight: creative ways to move not just against control, but beyond it.

    The real message of Postscript, however, is its invitation to consider a timeless perspective. Any society must have a way to make people useful. So, what kind of society do we want? What kinds of restrictions are we willing to live under? And, crucial to this current age, how explicit should control be?

  • MIL-OSI Analysis: Australia could become the world’s first net-zero exporter of fossil fuels – here’s how

    Australia is among the world’s top three exporters of LNG and second-largest exporter of coal. When burned overseas, these exports result in 1.1 billion tonnes of carbon dioxide emissions a year – almost three times Australia’s domestic emissions.

    Emissions embedded in Australia’s exports do not count towards our national emissions targets. But they contribute to climate change – and they’re the reason for Australia’s international reputation as a fossil-fuel economy.

    On the bright side, Australia boasts huge potential for low-cost renewable energy and a knack for resource industries.

    We can, and should, become a “renewable energy superpower”. This term refers to the potential for Australia to use its bountiful renewable energy resources to make commodities such as iron, ammonia and other products and fuels in “green” or low-emissions ways.

    So how does Australia give salience to this idea on the global stage, while our fossil fuel exports continue? The solution could be a new net-zero target for Australia, in which emissions from green exports are tallied up against those from fossil fuel exports.

    Reinvigorating Australia’s climate policy

    If the clean energy transition eventuates, green exports from Australia will rise over time. This will help reduce the use of coal, gas and oil elsewhere in the world.

    Meanwhile, coal exports – and later, gas exports – will fall. This will happen irrespective of Australia’s policies, as the world economy decarbonises and demand for fossil fuels slows.

    At some point, we can expect emissions avoided by our green commodity exports to surpass those from remaining coal and gas exports. Australia would then reach what could be termed “net-zero export emissions”.

    Adopting this net-zero target as a national policy would give a concrete yardstick to Australia’s green-export ambitions. It could also invigorate Australia’s climate policy and boost investor confidence.

    A different approach would be to set targets only for green exports, and this could be how we get started. Ultimately, a net-zero target wrapping up both green and fossil-fuel exports would speak most directly to the goal of tackling climate change, and is likely to have more impact on the international stage.

    Getting to net-zero exports

    The below chart shows an illustrative decline in emissions embedded in Australia’s coal and LNG (liquified natural gas) exports, out to 2050.*


    Authors’ calculations based on Australian Energy Update 2024, Australian National Greenhouse Accounts Factors 2024, IEA World Energy Outlook 2024

    It’s hard to pin down when Australia might reach net-zero exports. It depends on several factors. How quickly will the cost of clean energy and green-commodity technologies fall? How competitively can Australia produce green goods compared to other nations? What policies will be adopted in Australia and overseas – and will they work?

    The magnitudes are sobering. Take iron, for example. Australia currently exports 900 million tonnes of iron ore a year. This is processed overseas to about 560 million tonnes of iron.

    To fully compensate for emissions currently embedded in Australia’s coal and gas exports, Australia would need to process about the same amount of green iron – around 550 million tonnes – on home soil every year.

    To reach this figure, we assume 0.1 tonnes of CO₂-equivalent is created per tonne of green iron, compared to about 2.1 tonnes of CO₂-equivalent per tonne of iron resulting from conventional blast furnace production.

    Achieving this would require keeping iron ore production at current levels and processing it all in Australia, which is unlikely to be realistic.

    Thankfully, the task of reaching net-zero export emissions will be smaller in future, as global coal and gas demand falls. But exactly how this will translate to Australian exports is highly uncertain.

    Let’s suppose Australia’s exports evolved on the same trajectory as they might under current climate policies and pledges for the global coal and gas trade.

    In this case, embedded emissions from Australia’s coal and gas exports would be about 360 million tonnes in 2050. This includes about 120 million tonnes from LNG exports – much of it locked in by the extension to Woodside’s North West Shelf project off Western Australia.

    Hypothetically, the 360 million tonnes of emissions could be negated by a mix of green exports. They include 102 million tonnes of green iron (saving 204 million tonnes of CO₂), and 11 million tonnes of green ammonia (saving about 23 million tonnes of CO₂), and the remainder covered by a combination of green aluminium, silicon, methanol and transport fuels.

    Judgement calls would be needed about which commodities to include in the target. The composition of green exports suggested above is akin to assumptions about Australia’s potential global market share outlined by The Superpower Institute.

    Importantly, it’s hard to predict with certainty the greenhouse gas emissions displaced elsewhere in the world by Australia’s green exports. So, the estimates should be understood as broad illustrations, and not as exact as the accounting used to calculate countries’ domestic emissions.

    The precise year chosen for reaching a net-zero target for export emissions may well be less important than the commitment that, at some point, Australia’s green energy exports will exceed fossil fuel exports. This would establish the notion that Australia has the capacity and willingness to help the world decarbonise.

    A positive agenda for change

    The export target could be part of Australia’s updated emissions pledge due to be submitted to the United Nations by September this year. The pledge, known as a Nationally Determined Contribution (NDC), is required by signatories to the Paris Agreement.

    Each nation is expected to detail its national emissions target for 2035. But nations can make additional pledges towards the world’s climate change effort. You could call it an “NDC+”.

    So Australia could outline an indicative goal for net-zero exports – perhaps alongside other pledges such as leveraging climate change finance for developing countries, or helping our Pacific neighbours adapt to climate change impacts.

    As a large fossil fuels exporter, Australia would earn kudos for showing it has a positive agenda for change.

    And if Australia wins the bid to host the COP31 climate conference next year, a plan to reduce export emissions could be a major rallying point.

    * Underlying data for the chart showing an expected decline in future emissions embedded in Australia’s coal and LNG exports:

    Exports in 2022–23: coal, 9.6 exajoules (EJ); LNG, 4.5 EJ, from Australian Energy Update. This was multiplied by an emissions factor 90.2 for coal (MtCO₂-e/EJ) and 51.5 for LNG (MtCO₂-e/EJ), as drawn from the Australian National Greenhouse Accounts Factors

    Exports for 2035 and 2050: this assumes a trend aligned with the IEA’s Announced Pledges Scenario, as outlined in the World Energy Outlook 2024. Note the percentage changes from 2023 to 2035 and 2050 for coal (-45% and -73% respectively) and for LNG (+9% and -47% respectively.) These figures do not distinguish between steam coal for power and metallurgical coal.

  • MIL-OSI Analysis: How high can US debt go before it triggers a financial crisis?

    Source: The Conversation – Global Perspectives – By Luke Hartigan, Lecturer in Economics, University of Sydney

    The tax cuts bill currently being debated by the US Senate will add another US$3 trillion (A$4.6 trillion) to US debt. President Donald Trump calls it the “big, beautiful bill”; his erstwhile policy adviser Elon Musk called it a “disgusting abomination”.

    Foreign investors have already been rattled by Trump’s upending of the global trade system. The eruption of war in the Middle East would usually lead to “flight to safety” buying of the US dollar, but the dollar has barely budged. That suggests US assets are not seen as the safe haven they used to be.

    Greg Combet, chair of Australia’s own sovereign wealth fund, the Future Fund, outlined many of the new risks arising from US policies in a speech on Tuesday.

    As investors turn cautious on the US, at some point the surging US debt pile will become unsustainable. That could risk a financial crisis. But at what point does that happen?

    The public sector holds a range of debt

    When talking about the sustainability of US government debt, we have to distinguish between total debt and public debt.

    Public debt is owed to individuals, companies, foreign governments and investors. This accounts for about 80% of total US debt. The remainder is intra-governmental debt held by government agencies and the Federal Reserve.

    Public debt is a more correct measure of US government debt. And it is much less than the headline total government debt amount that is frequently quoted, which is running at US$36 trillion or 121% of GDP.

    Are there limits to government debt?

    Governments are not like households. They can feasibly roll over debt indefinitely and don’t technically need to repay it, unlike a personal credit card. And countries such as the US that issue debt in their own currency can’t technically default unless they choose to.

    Debt also serves a useful role. It is the main way a government funds infrastructure projects. It is an important channel for monetary policy, because the US Federal Reserve sets the benchmark interest rate that affects borrowing costs across the economy. And because the US government issues bonds, known as Treasuries, to finance the debt, this is an important asset for investors.

    There is probably some limit to the amount of debt the US government can issue. But we don’t really know what this amount is, and we won’t know until we get there. Additionally, the US’s reserve currency status, due to the US dollar’s dominant role in international finance, gives the US government more leeway than other governments.

    Interest costs are surging

    What is important is the government’s ability to service its debt – that is, to pay the interest cost. This depends on two components: growth in economic activity, and the interest rate on government debt.

    If economic growth on average is higher than the interest rate, then the government’s effective interest cost is negative and it could sustainably carry its existing debt burden.

    The interest cost of US government debt has surged recently following a series of Federal Reserve interest rate hikes in 2022 and 2023 to quell inflation.

    The US government is now spending more on interest payments than on defence – about US$882 billion annually. This will soon start crowding out spending in other areas, unless taxes are raised or further spending cuts made.

    Recent policy decisions not helping

    The turmoil caused by Trump’s “Liberation Day” tariffs and heightened uncertainty about future government policy are expected to weaken US economic growth and raise inflation. This, coupled with the recent credit downgrade of US government debt by ratings agency Moody’s, is likely to put upward pressure on US interest rates, further increasing the servicing cost of US government debt.

    Moody’s cited concerns about the growth of US federal debt. This comes as the US House of Representatives passed the “One Big Beautiful Bill Act”, which seeks to extend the 2017 tax cuts indefinitely while slashing social spending. This has caused some to question the sustainability of the US government’s fiscal position.

    The non-partisan Congressional Budget Office estimates the bill will add a further US$3 trillion to government debt over the ten years to 2034, increasing debt to 124% of GDP. And this would increase to US$4.5 trillion over ten years and take debt to 128% of GDP if some tax initiatives were made permanent.

    Also troubling is Section 899 of the bill, known as the “revenge tax”. This controversial provision raises the tax payable by foreign investors and could further deter foreign investment, potentially making US government debt even less attractive.

    A compromised Federal Reserve is the next risk

    The passing of the tax and spending bill is unlikely to cause a financial crisis in the US. But the US could be entering into a period of “fiscal dominance”, which is just as concerning.

    In this situation, the independence of the Federal Reserve might be compromised if it is pressured to support the US government’s fiscal position. It would do this by keeping interest rates lower than otherwise, or buying government debt to support the government instead of targeting inflation. Trump has already been putting pressure on Federal Reserve chair Jerome Powell, demanding he cut rates immediately.

    This could lead to much higher inflation in the US, as occurred in Germany in the 1920s, and more recently in Argentina and Turkey.

  • MIL-OSI Analysis: The Weimar triangle: how Germany’s new government could reinvigorate an important European security alliance

    Source: The Conversation – UK – By Rachel Herring, PhD candidate, Department of Politics, History and International Relations, Aston University

    Decisions made by German chancellor Friedrich Merz when he came to power in May indicate that a somewhat dormant regional partnership is about to take on new significance in Europe. Merz immediately travelled to Paris and Warsaw to meet Emmanuel Macron and Donald Tusk, suggesting the so-called Weimar triangle is a top priority for his government.

    Following Merz’s visit to Poland, Polish prime minister Tusk declared “a new beginning, perhaps the most important in the history of the last dozen or so years, in Polish-German relations”.

    If Tusk is right, the Weimar triangle – an alliance between France, Germany and Poland – will have a key role to play. The Weimar triangle was established in 1991 as a forum for the three countries to work together in the interest of European security. This involved integrating Poland into the EU, as well as providing another channel for Germany to pursue friendship and reconciliation with its neighbours.

    The Franco-German “special relationship” was already established, along with their shared reputation as Europe’s “motor”. But Poland’s inclusion was crucial. As a large, influential country in Central Europe, it was well placed to become a pillar of European security and a partner in European expansion following the collapse of Communist regimes.

    As well as being a smaller security forum in which Germany, France and Poland can find common ground on EU security and foreign policy, the Weimar triangle has at times taken on an active international role. During the 2014 Ukraine crisis, ministers from the three Weimar triangle countries took the lead and negotiated on behalf of the EU.

    However, the importance and effectiveness of the format has declined in recent years due to deteriorating relations between the French, German and Polish governments.

    Russia’s invasion of Ukraine in February 2022 elevated the significance of the Weimar triangle once again. But in the early days of the war, although all three governments condemned the invasion, Poland, Germany and France were far from being on the same page.

    Germany’s cautious response provoked criticism in Poland – and indeed in other Central European countries. Many in the region had long been sceptical of Germany’s Russia policy and had warned of Russian aggression, but did not feel taken seriously.

    While the Polish government was quick to commit significant military support to Ukraine, Germany, under former chancellor Olaf Scholz, soon gained a reputation for being overly cautious in the eyes of its more hawkish allies. This led the Polish government to begin turning to security alliances in Scandinavia and the Baltics.

    Meanwhile, Scholz’s hesitancy and orientation towards Washington for leadership was also met with frustration in France, where the idea of “European sovereignty” in security issues had more traction.

    When the new Merz government made it clear that it wanted to prioritise foreign policy and the Weimar triangle, there was a sense that things were about to change. It is still early days, but the rhetoric of all three Weimar triangle leaders signals a commitment to making the alliance finally deliver, as well as an awareness of earlier failures.

    New challenges in Poland

    It won’t be plain sailing from here though. The election of nationalist Karol Nawrocki as president in Poland in early June was a blow for those that support a new, strong Weimar triangle.

    Poland’s current government is a centrist coalition led by pro-European prime minister Donald Tusk, but the concern now is that Nawrocki will block pro-European legislation as his predecessor did, given that he has the support of the nationalist, Eurosceptic Law and Justice (PiS) party. The PiS party (in government from 2015-2023) has a record of anti-German and anti-EU rhetoric.

    Nawrocki has not yet questioned Poland’s military aid to Ukraine but the Tusk government must now continue to balance pursuing its own more liberal agenda and more pro-German and pro-European approach with the alternative views that Nawrocki represents, and which are clearly backed by a significant portion of Polish voters.

    What next for the Weimar triangle?

    Given the centrality of the Weimar triangle countries in Europe and the EU, their alliance has consequences that go far beyond the bilateral and regional levels. With the ongoing war in Ukraine and the uncertain status of the US as a security partner since Donald Trump’s re-election, a strong and unified pillar at the centre of Europe would be an asset to the EU and European security.

    So far, the Weimar triangle has failed to deliver on the expectations attached to it, often due to domestic differences. However, it holds untapped potential. A divided Europe and EU is in the interest of Putin’s government, and is not the unified ally Ukraine needs.

    The Weimar triangle, in bringing together three key member states – crucially including from Central Europe – can both symbolically and practically strengthen European foreign and security policy.

    This will involve finding compromises to build a united front on security at the EU level, bringing issues and policies to the table, and strengthening understanding where security perspectives diverge. The positions and signals of France, Germany and Poland matter to other EU member states and to Ukraine. Joint efforts could have even more clout.

  • MIL-OSI Analysis: Here We Are: how silence defines Stephen Sondheim’s last musical

    Source: The Conversation – UK – By Ben Macpherson, Reader in Vocal Theatres, University of Portsmouth

    In musical theatre lore, when emotion outgrows words, characters sing (and when emotion outgrows song, they dance). This idea – in various guises, configurations and subversions – has shaped musical theatre for the last eight decades. The expectation that in a musical, characters sing is deeply ingrained: songs move the story along, or suspend time to enlarge a moment of emotion.

    Songs give audiences a chance to connect and to thrill at the virtuosity – and vulnerability – on display. After all, the very term “musical theatre” gives us a clue to its priorities. What happens, then, when the singing stops?

    That is the question posed by Stephen Sondheim’s final musical, Here We Are, which premiered at The Shed in New York in 2023 (two years after his death at 91) and is now playing at The National Theatre in London till the end of June.

    Based on two surrealist films by Spanish auteur Luis Buñuel (1972’s The Discreet Charm of the Bourgeoisie and 1962’s The Exterminating Angel), act one sees a group of wealthy friends searching for a decent brunch.

    In act two, after finally eating in the dining room of an embassy building, they mysteriously find themselves trapped – along with the waitress and the butler – and unable to leave. Completed posthumously and written with playwright David Ives, the show does something radical: in its second act, the characters stop singing.

    That is not to say the show is not musical, and act two does include three brief moments of musical interlude rather than song. We might suggest this “songlessness” acts as a kind of silence; the characters speak, but as this is not a play, they should – as is expected of a musical – sing.

    Initially keeping up appearances, act one is full of group numbers and sung encounters, yet even here, Sondheim plays games with his audience. The main characters rarely get solo moments; instead, minor characters, including a waiter and a soldier, are given richly expressive songs.

    The usual power dynamics of musical theatre are inverted. Who gets to sing – and who does not – becomes central to the story. Director Joe Mantello has said that this approach was counterintuitive, even for Sondheim.

    By act two, the playfulness escalates. Suddenly, not even the piano in the embassy drawing room makes a sound. Silence here is not simply a gap to be filled – it becomes the point of the drama. Audiences are asked to sit with characters inured to privilege and trapped by their sudden helplessness.

    The absence of song draws attention to everything else: the dynamics and relationships, the constrained movement, the increasingly stilted small talk. Without the emotional release of song, these characters are confronted, confronting and exposed.

    Musical silence and space

    This seems a courageous move in a genre built around song – but in fact, there are many examples in musical theatre where characters who do not sing are nonetheless central. In West Side Story (1957) and Spring Awakening (2006), adults are silent while the youth give voice to generational difference.

    In The Drowsy Chaperone (1998), the central narrator talks but never sings. In more recent works like Maybe Happy Ending (2016), the silence of not singing is more comedic, with the main character Oliver’s best friend being a (silent) house plant named HwaBoon. But Here We Are takes the idea further. Why?

    One reason is dramatic. The characters are trapped in an illogical, surreal situation, leading Sondheim to reportedly ask: “Why would these people be singing when they’re trapped in this room?” To its composer, the emotional directness of singing seemed inappropriate here.

    Instead, as with the ambiguity that characterises much of Sondheim’s work, we get something more open-ended, perhaps even rebellious. Without the usual musical release, tension builds. What do these characters really feel? What does their inaction demonstrate?

    The kind of musical silence gives rise to such questions, becoming a space in which characters and audiences can reflect, transform and critique. The second act of Here We Are is not simply a story about people who cannot leave a room – it is about being confined by habits, class structures and privilege. Characters and audiences alike are forced to confront these things without the thrill of song to soften the edges.

    Here We Are further plays with musical theatre’s deepest conventions. What if the thing we expect most – the habit and structure of singing in a musical – does not happen? What if the absence of singing is the most powerful sonic gesture of all?

    To end his final work in this way feels like Sondheim has played one last trick on his audience. After a career of writing some of the most emotionally complex songs in musical theatre – such as Send in the Clowns from A Little Night Music – he leaves us with one final challenge to the structure of the form he expanded.

    In an interview with journalist Adam Gopnik of The New Yorker in 2014, Sondheim said his dream project would be “not writing”. With Here We Are, he was almost there.

  • MIL-OSI Analysis: Five common habits that might be harming your liver

    Source: The Conversation – UK – By Dipa Kamdar, Senior Lecturer in Pharmacy Practice, Kingston University

    Paracetamol overdose is one of the leading causes of acute liver failure, according to the British Liver Trust fizkes/Shutterstock

    The liver is one of the hardest working organs in the human body. It detoxifies harmful substances, helps with digestion, stores nutrients, and regulates metabolism.

    Despite its remarkable resilience – and even its ability to regenerate – the liver is not indestructible. In fact, many everyday habits, often overlooked, can slowly cause damage that may eventually lead to serious conditions such as cirrhosis (permanent scarring of the liver) or liver failure.

    One of the challenges with liver disease is that it can be a silent threat. In its early stages, it may cause only vague symptoms like constant fatigue or nausea.

    As damage progresses, more obvious signs may emerge. One of the most recognisable is jaundice, where the skin and the whites of the eyes turn yellow. While most people associate liver disease with heavy drinking, alcohol isn’t the only culprit. Here are five common habits that could be quietly harming your liver.

    1. Drinking too much alcohol

    Alcohol is perhaps the most well-known cause of liver damage. When you drink, your liver works to break down the alcohol and clear it from your system. But too much alcohol overwhelms this process, causing toxic by products to build up and damage liver cells.

    Alcohol-related liver disease progresses in stages. At first, fat begins to accumulate in the liver (fatty liver), often without any noticeable symptoms and reversible if drinking stops. Continued drinking can lead to alcoholic hepatitis, where inflammation and scar tissue begin to form as the liver attempts to heal itself.

    Over time, this scarring can develop into cirrhosis, where extensive hardening of the liver seriously affects its ability to function. While cirrhosis is difficult to reverse, stopping drinking can help prevent further damage.

    Even moderate drinking, if sustained over many years, can take its toll, particularly when combined with other risk factors like obesity or medication use. Experts recommend sticking to no more than 14 units of alcohol per week, and including alcohol-free days to give your liver time to recover.

    2. Poor diet and unhealthy eating habits

    You don’t need to drink alcohol to develop liver problems. Fat can build up in the liver due to an unhealthy diet, leading to a condition now called metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD).

    Excess fat in the liver can impair its function and, over time, cause inflammation, scarring, and eventually cirrhosis. People who are overweight – particularly those who carry excess weight around their abdomen – are more likely to develop MASLD. Other risk factors include high blood pressure, diabetes and high cholesterol.

    Diet plays a huge role. Foods high in saturated fat, such as red meat, fried foods and processed snacks, can raise cholesterol levels and contribute to liver fat accumulation. Sugary foods and drinks are also a major risk factor. In 2018, a review found that people who consumed more sugar sweetened drinks had a 40% higher risk of developing fatty liver disease.

    Ultra-processed foods such as fast food, ready meals and snacks packed with added sugar and unhealthy fats also contribute to liver strain. A large study found that people who ate more processed foods were significantly more likely to develop liver problems.

    On the flip side, eating a balanced, wholefood diet can help prevent – and even reverse – fatty liver disease. Research suggests that diets rich in vegetables, fruit, whole grains, legumes, and fish may reduce liver fat and improve related risk factors such as high blood sugar and cholesterol.

    Staying hydrated is also important. Aim for around eight glasses of water a day to support your liver’s natural detoxification processes.

    3. Overusing painkillers

    Many people turn to over-the-counter painkillers such as paracetamol for headaches, muscle pain, or fever. While generally safe when used as directed, taking too much – even slightly exceeding the recommended dose – can be extremely dangerous for your liver.

    The liver breaks down paracetamol, but in the process, produces a toxic by-product called NAPQI. Normally, the body neutralises NAPQI using a protective substance called glutathione. However, in an overdose, glutathione stores become depleted, allowing NAPQI to accumulate and attack liver cells. This can result in acute liver failure, which can be fatal.

    Even small overdoses, or combining paracetamol with alcohol, can increase the risk of serious harm. Always stick to the recommended dose and speak to a doctor if you find yourself needing pain relief regularly.

    Regular exercise is one of the simplest and most powerful ways to protect your liver.

    4. Lack of exercise

    A sedentary lifestyle is another major risk factor for liver disease. Physical inactivity contributes to weight gain, insulin resistance, and metabolic dysfunction – all of which can promote fat accumulation in the liver.

    The good news is that exercise can benefit your liver even if you don’t lose much weight. One study found that just eight weeks of resistance training reduced liver fat by 13% and improved blood sugar control. Aerobic exercise is also highly effective: regular brisk walking for 30 minutes, five times a week, has been shown to reduce liver fat and improve insulin sensitivity.

    5. Smoking

    Most people associate smoking with lung cancer or heart disease, but many don’t realise the serious damage it can do to the liver.

    Cigarette smoke contains thousands of toxic chemicals that increase the liver’s workload as it tries to filter and break them down. Over time, this can lead to oxidative stress, where unstable molecules (free radicals) damage liver cells, restrict blood flow, and contribute to scarring (cirrhosis).

    Smoking also significantly raises the risk of liver cancer. Harmful chemicals in tobacco smoke, including nitrosamines, vinyl chloride, tar, and 4-aminobiphenyl, are all known carcinogens. According to Cancer Research UK, smoking accounts for around 20% of liver cancer cases in the UK.

    Love your liver

    The liver is a remarkably robust organ – but it isn’t invincible. You can protect it by drinking alcohol in moderation, quitting smoking, taking medications responsibly, eating a balanced diet, staying active and keeping hydrated.

    If you notice any symptoms that may suggest liver trouble, such as ongoing fatigue, nausea, or jaundice, don’t delay speaking to your doctor. The earlier liver problems are detected, the better the chance of successful treatment.

  • MIL-OSI Analysis: The UK failed grooming gang victims by not seeing ‘children as children’

    Source: The Conversation – UK – By Michelle McManus, Professor of Safeguarding and Violence Prevention, Co-Director of the Institute for Children’s Futures, Manchester Metropolitan University

    The announcement of a national inquiry into group-based child sexual exploitation raises urgent questions: How did we end up here again? Haven’t there been enough reports? Why weren’t children protected the first time? And will these reforms actually change anything?

    As someone who has worked for years in safeguarding policy and research into grooming, county lines drug trafficking and child criminal exploitation, I believe this moment could be different. For the first time in years, there is political momentum, public scrutiny and survivor-led demand for change all converging. But we have to honest about how we got here.

    The inquiry, which will have full statutory powers, follows crossbench peer Louise Casey’s rapid national audit into grooming gangs. Her report lays bare what the Home Secretary, Yvette Cooper, described as a “collective failure” over 15 years. This phrase reflects not just high-profile cases in Rotherham, Rochdale or Telford, but a nationwide pattern of authorities disbelieving victims, delaying action and denying the scale of the problem.

    Since 2014, inquiry after inquiry has revealed how children, often girls, care-experienced young people, or those from marginalised backgrounds were not listened to, with some dismissed by social services as making “life choices”. Despite the Jay report, the 2022 Telford inquiry, and the independent inquiry into child sexual abuse, victims were often not seen as victims at all.

    Seeing ‘children as children’

    One of the most striking lines in Lady Casey’s audit came just before her 12 recommendations: “We need to see children as children.” This cuts to the heart of how so many victims were failed. When professionals view teenagers as complicit, consenting, or “making choices”, they stop seeing the child in need of protection.

    Casey revealed that even today, many victims are still falling through the cracks because their exploitation doesn’t fit assumptions. The report revealed that cases involving 13- to 15-year-olds were too often dropped or downgraded from rape, with professionals referencing that the child was “in love” or had “consented”.

    These interpretations ignore the law — which sets the age of consent at 16 — and more importantly, they ignore the power imbalance and coercion at the heart of grooming. Casey has called for the law to be unambiguous: any penetrative sex with a child under 16 must be classified as rape.

    This failure to see children as victims is deeply embedded. In 2023, 706 group-based child sexual exploitation offences were recorded. A number dwarfed by the estimated 500,000 annual cases of child sexual abuse in England and Wales.

    Sign up for our weekly politics newsletter, delivered every Friday.

    One reason for this gap, as Casey’s audit acknowledges, is that “the results tend to obscure rather than clarify the picture of group-based child sexual exploitation”. Much abuse is made invisible by confusing and inconsistently applied definitions, where grooming is recorded under unrelated offence types such as gang or drug crime, rather than identified as exploitation.

    In my own research and parliamentary evidence, I’ve repeatedly warned that when a child is caught carrying drugs or cash, they are too often seen as a criminal first — not as someone coerced, groomed or harmed.

    These assumptions directly shape the outcome of a case. In earlier grooming gang cases identified in the various inquiries, girls were seen as “promiscuous” or as having “chosen” to associate with older men. These narratives made it easier for agencies to downplay reports, delay interventions or ignore disclosures altogether.

    Casey rightly highlights how exploiters have taken advantage of the blurred legal and professional treatment of 13- to 15-year-olds in sexual exploitation cases. But it is concerning that proposed legislation (the crime and policing bill) appears to replicate the same flaws in how it treats child criminal exploitation. The bill introduces different assumptions about a young person’s “awareness” or involvement, even where grooming or coercion is present.

    This risks embedding a double standard: one where a 14-year-old can’t consent to sex, but can be seen as knowingly trafficking drugs. Without urgent scrutiny, we risk repeating the same failures but under the banner of criminal exploitation. It is still child exploitation.

    What’s different about these reforms?

    The government has accepted all 12 of Casey’s recommendations, including making ethnicity data collection mandatory and fast-tracking rape charges for adults abusing under-16s.

    It has also promised mandated data-sharing to finally resolve the communication failures that have dogged policing, social care and health services for decades.

    The Casey audit underscores how urgent these reforms are. It found that two-thirds of recorded perpetrators had no ethnicity data captured, making it impossible to draw clear national conclusions. In areas like Greater Manchester and South Yorkshire, there was evidence of over-representation among men of Asian ethnicity.

    But the data-sharing failures go far beyond demographics. In many serious case reviews, including ones I’ve worked on, key information held by one agency (such as frequent missing episodes recorded by police) were never pieced together across agencies. Mandated data-sharing could have allowed professionals to spot patterns of grooming earlier and intervene before exploitation escalated.

    We’ve seen versions of these promises before. The independent inquiry into child sexual abuse made over 80 recommendations. The Jay report outlined repeated missed chances to intervene. In 2022, the Centre of expertise on child sexual abuse called for urgent reforms to how police and social workers identify and respond to child sexual exploitation. Many of those changes were either delayed, diluted or quietly dropped.

    Some changes, such as the statutory inquiry’s power to compel evidence, are welcome. But legal duty doesn’t automatically translate into professional confidence or competence. The systems and infrastructure needed to enable professionals to share data consistently and safely still do not exist.

    I’ve observed how even the most robust policy and guidance fails in practice because professionals are underresourced, overwhelmed, lack experience, or are unprepared to challenge risk-averse decision making.

    For example, mandated data-sharing has been a goal since the 1980s. It was a central recommendation in the 1987 Cleveland inquiry and the 2000 Victoria Climbié inquiry, both of which dealt with child abuse. It has remained a consistent theme in reviews from the child safeguarding practice review panel and in my own national evaluations.

    Case reviews across four decades have cited the same failures: organisations not talking to each other, files siloed, risks misunderstood. In the cases explored in the Casey audit, better data-sharing could have helped agencies identify patterns of concern much earlier, including young people going missing from home or school, presenting at sexual health clinics, or being repeatedly reported in distress by family members, teachers and health practitioners.

    Instead, these signs remained isolated. Without a full picture, no single agency recognised what was happening. Children were left unprotected while perpetrators continued to offend.

    Unless we address why so many professionals have historically avoided taking action, whether due to fear of being seen as racist, fear of reputational harm, or simply not believing children, reforms may look good on paper but fall short in reality.

    The Casey audit shows we haven’t just failed to act, we’ve failed to learn. “Collective failure” is a powerful phrase, but without collective responsibility, we risk repeating the cycle.

  • MIL-OSI Analysis: Alzheimer’s: bacteria that causes stomach ulcers may protect the brain, our new research indicates

    Source: The Conversation – UK – By Gefei Chen, Associate professor, Karolinska Institutet

    Every three seconds, someone in the world develops dementia. Alzheimer’s disease is the most common form of dementia, accounting for between 60% and 70% of all cases.

    Although scientists have made significant progress in understanding the disease, there’s still no cure. That’s partly because Alzheimer’s disease has multiple causes – many of which are still not fully understood.

    Two proteins which are widely believed to play central roles in Alzheimer’s disease are amyloid-beta and tau. Amyloid-beta forms sticky plaques on the outside of brain cells. This disrupts communication between neurons. Tau accumulate inside brain cells, where it twists into tangles. This ultimately leads to cell death. These plaques and tangles are the hallmark features of Alzheimer’s disease.

    This understanding, known as the amyloid hypothesis, has shaped research for decades and led to treatments that aim to clear amyloid from the brain. Monoclonal antibody drugs have been approved in recent years for this purpose.

    But they only work in the early stages of the disease. They do not reverse existing damage and may cause serious side-effects such as brain swelling and bleeding. Most importantly, they only target amyloid-beta, leaving tau untreated.

    But in a surprise twist, recent research published by my colleagues and me has found that a protein from Helicobacter pylori – a bacteria best known for causing stomach ulcers – can block the toxic buildup of both amyloid-beta and tau. This unexpected finding may point to a new strategy for the fight against Alzheimer’s disease.

    Our discovery began with a very different question. We were initially studying how H pylori interacts with other microbes. Some bacteria form protective communities called biofilms, which rely on amyloid assemblies (similar in structure to the plaques which form in the brain) as a structural scaffold. This led us to wonder: could H pylori influence bacterial biofilms by also interfering with amyloid assemblies in humans?

    We turned our attention to a well-known H pylori protein called CagA. While half of the protein is known to trigger harmful effects in human cells (referred to as the C-terminal region), the other half (the protein’s N-terminal region) may have protective properties. To our surprise, this N-terminal fragment, called CagAN, dramatically reduced the formation of both bacterial amyloids and biofilms in the bacterial species Escherichia coli and Pseudomonas.

    Encouraged by these results, we tested whether the same protein fragment could block the buildup of human amyloid-beta proteins. To do this, we incubated amyloid-beta molecules in the lab: some were treated with CagAN, while others were left as normal. We then tracked amyloid formation using a fluorescence reader and an electron microscope.

    The protein derived from H pylori blocked amyloid-beta plaques from forming.

    We found that treated samples had far less amyloid clump formation during the testing period. Even at very low concentrations, CagAN almost completely stopped amyloid-beta from forming amyloid aggregates.

    To understand how CagAN worked, we used nuclear magnetic resonance (which allows us to look at how molecules interact with each other) to examine how the protein interacts with amyloid-beta. We also used computer modelling to investigate possible mechanisms. Remarkably, CagAN also blocked tau aggregation – suggesting it acts on multiple toxic proteins involved in Alzheimer’s disease.

    Blocking the disease

    Our study has shown us that a fragment from the Helicobacter pylori protein can effectively block the buildup of the two proteins that are implicated in Alzheimer’s disease. This suggests that bacterial proteins – or drugs modelled after them – could someday block the earliest signs of Alzheimer’s.

    What’s more, the benefits may extend beyond Alzheimer’s disease.

    In additional experiments, the same bacterial fragment blocked the aggregation of IAPP (a protein involved in type 2 diabetes) and alpha-synuclein (linked to Parkinson’s disease). All of these conditions are driven by the accumulation of toxic amyloid aggregates.

    That a single bacterial fragment could interfere with so many proteins suggests exciting therapeutic potential. Though these conditions affect different parts of the body, they may be linked through cross-talk between amyloid proteins – a shared mechanism that CagAN could help disrupt.

    Of course, it’s important to be clear: this research is still at an early stage. All of our experiments were conducted in lab settings, not yet in animals or humans. Still, the findings open a new path.

    Our study also uncovered the underlying mechanisms for how CagAN blocked the amyloid-beta and tau from forming amyloid aggregates. One of the ways in which CagAN did this was by preventing the proteins from coming together to form clumps. They also prevented small, premature amyloid aggregates from forming as well. In the future, we will continue the detailed mechanism study and evaluate the effects in animal models.

    These results also prompt a question: could H pylori, long seen only as harmful, also have a protective side? Some studies have hinted at a connection between H pylori infection and Alzheimer’s disease, though the relationship remains unclear. Our discovery adds a new layer to this discussion, suggesting that part of H pylori may actually interfere with the molecular events that lead to Alzheimer’s disease.

    That means in the future, we may need to take a more precise and personalised approach. Instead of aiming to eliminate H pylori completely with antibiotics, it might be more important to understand, in different biological contexts, which parts of the bacterium are harmful, and which might actually be beneficial.

    As medicine continues to move toward greater precision, the goal may no longer be to wipe out every microbe, but to understand how some of them might work with us rather than against us.

  • MIL-OSI Analysis: Brazil’s ‘bill of devastation’ pushes Amazon towards tipping point

    Source: The Conversation – Global Perspectives – By Philip Fearnside, Biólogo e pesquisador titular (Departamento de Ecologia), Instituto Nacional de Pesquisas da Amazônia (INPA)

    A bill essentially abolishing Brazil’s environmental licensing system is just days away from likely passage by the country’s National Congress. Despite the environmental discourse of President Luiz Inácio “Lula” da Silva, what is known as the “bill of devastation” (PL 2159/2021) apparently has his tacit approval. Even if Lula vetoes the bill, anti-environmental voting blocks in the National Congress have more than the 60% in each house needed to override a veto.

    The “bill of devastation” has been promoted as relieving “low impact” projects of unnecessary bureaucracy, but it is very much more than this. First, it is for both “low” and “medium” impact projects, two categories that are vaguely defined, allowing projects with major impacts to be benefitted. The bill applies to licensing at both the state and federal levels, and at the state level there is expected to be a “race to the bottom” as states compete to attract investments by loosening environmental restrictions.

    The “medium impact” category is a misnomer, as it includes most mining projects such as the mine tailings dams that broke in 2015 at Mariana and in 2019 at Brumadinho to create two of Brazil’s worst environmental disasters.

    Under the bill, these “low” and “medium” impact projects would be licensed by what is known as “self-licensing,”. This eliminates the need for an environmental impact assessment, public hearings and specification of compensatory measures in the event of accidents or other impacts. Basically, this self-declared statement consists of checking a series of boxes on an online form.

    Bypassing any public or committee debate, at the last minute before the Senate’s plenary vote the bill was modified with an amendment that increased its environmental impact even more. The amendment created a “Special Environmental License” that would allow any project considered to be “strategic” to have an accelerated approval process, regardless of the magnitude of its impacts.

    The amendment is believed to be specifically intended to facilitate the controversial mouth-of-the-Amazon oil project, which has major potential impacts both from potentially uncontrollable oil spills and from its impact on climate change.

    Brazil’s imminent climate disaster

    Global climate and the Amazon forest are both approaching tipping points where the process of collapse escapes from human control. These imminent disasters are intertwined: if the Amazon forest were to collapse it would release more than enough greenhouse gases to push global temperatures beyond the point where human society loses the option to contain climate change by cutting emissions to zero, and if global temperatures rise uncontrollably, it would soon push the Amazon forest to collapse.

    The Amazon forest is on the verge of tipping points in terms of temperature, the ongoing increase in dry season length, the percentage of forest cleared and a combination of various climatic and direct anthropogenic impacts.

    The loss of the Amazon forest that would result from crossing any of these tipping points would, among other impacts, sacrifice the forest’s vital role in recycling water.

    A volume of water greater than the Amazon River’s total flow is released as water vapor by the leaves of the trees, providing rainfall that not only maintains Amazon forest but also maintains agriculture and city water supplies in other parts of Brazil and in neighboring countries. The water vapor is transported by winds known as “flying rivers” to São Paulo, the World’s fourth largest city, which depends on this water supply.

    Amazon destruction

    Given these catastrophic prospects, Brazil’s government should be acting decisively to halt the country’s greenhouse gas emissions and to lead the World in combatting climate change. These necessities are interrelated, as effective leadership is done through example and Brazil cannot continue to merely exhort other countries to reduce their emissions when its domestic decisions are acting to increase global warming. This includes the “bill of devastation”.

    Rapidly phasing out fossil fuel use is fundamental to containing global warming. The amount by which human society must reduce its emissions and the trajectory in time that this reduction must follow are determined by analysis of the best available data and climate models.

    The “Global Stocktake” by the Climate Convention, released at COP-28 in 2023, showed that anthropogenic emissions must decline by 43% by 2030 compared to 2023, and by 84% by 2050 to stay within the limit currently agreed under the Paris Agreement of 1.5 ºC above the pre-industrial average global temperature.

    This limit represents a tipping point both for the global climate system and for the Amazon forest. Above this point there is a sharp increase in the annual probability of uncontrollable feedbacks driving the system to a catastrophic shift or collapse.

    The mouth-of-the-Amazon project is critical. A massive auction of drilling rights, both onshore and offshore, is scheduled for 17 June, including 47 blocks in the mouth of the Amazon River.

    Environmental approval of the first “experimental” well (FZA-M-59) is viewed as the key to international oil companies being willing to bid on these blocks. The head of the Brazilian licensing agency (IBAMA) has been under intense pressure to approve the project.

    Oil project

    Within the licensing debate, the focus is almost entirely on whether Petrobras has the infrastructure and personnel to mount a rescue operation for marine wildlife in the event of an oil spill, rather than the more basic question of whether a leak could be plugged if it should occur.

    Unfortunately, there are strong indications that a leak could not be plugged for months or years, as the site has double the 1.5-km water depth at the Deepwater Horizon well in the Gulf of Mexico that spilled uncontrollably for five months in 2010, and the ocean currents are much stronger and more complex in the mouth of the Amazon.

    Petrobras constantly brags about its long experience with offshore oil extraction, but neither Petrobras nor any other company has plugged a leak at a location with the depth and complexity of the mouth-of-the-Amazon site.

    Containing global warming is inconsistent with opening new oil fields due to the economic logic of these projects, which is different from the economics of continued extraction of existing oilfields. This is what led the International Energy Agency (IEA) to recommend that no new oil or gas fields be opened anywhere in the World.

    In the case of the mouth of the Amazon project, the expectation is that it would take five years to begin commercial production and another five years to pay for the investment; since no one will want to stop with zero profit, the project implies extracting petroleum for many years after that – far beyond the time when the World must stop using oil as fuel.

    Petrobras claims that the mouth-of-the-Amazon project and other planned new oilfields are needed for Brazil’s “energy security” to guarantee that Brazilians will not lack fuel for their vehicles.

    The falsity of this argument is obvious from the fact that Brazil currently exports over half of the oil it extracts, and this percentage is expected to rise with the planned expansion. The reserves in Brazil’s existing oilfields are far greater than what the country can consume before fossil-fuel use must cease. In other words, the expansion of oil extraction is purely a matter of money.

    Another argument promoted by Petrobras and by President Lula is that the oil revenue is needed to pay for Brazil’s energy transition. While the energy transition must indeed be paid for, it should have a guaranteed place in Brazil annual budget, like health and education, and not be treated as something optional that depends on windfall financial gains.

    President Lula’s sleepwalk

    President Lula apparently lacks understanding of Brazil’s suicidal course towards a climate catastrophe. He has surrounded himself with proponents of projects with enormous climatic consequences, such as his minister of transportation who presses for Highway BR-319 and his minister of mines and energy and the president of Petrobras who push for the mouth-of-the-Amazon and other new oil and gas projects.

    Clearly, Lula does not listen to his minister of environment and climate change on these issues. He lives in a “disinformation space,” to use the term coined by Ukrainian President Volodymyr Zelinski to describe Donald Trump. The question of whether President Lula will awake from his sleepwalk before COP-30 in November is critical, as this is his opportunity to assume global leadership on climate change. Although there is no indication that this is likely, efforts to penetrate his disinformation space must continue.

  • MIL-OSI Analysis: China’s support for Mali’s military carries risks: researcher outlines what they are

    Source: The Conversation – Africa – By Paa Kwesi Wolseley Prah, Postdoctoral Fellow, Dublin City University

    Mali, a landlocked Sahelian nation of 25 million people, has faced significant instability since 2012, marked by terrorism, state neglect and armed conflicts.

    That year a Tuareg rebellion started in northern Mali and President Amadou Toumani Touré was ousted in a military coup. Constitutional rule was suspended. Rebels in northern Mali went on to seize cities like Timbuktu, Gao and Kidal, declaring an independent Islamic State of Azawad and imposing sharia law.

    They also destroyed cultural heritage sites, including 14 of Timbuktu’s 16 Unesco-listed mausoleums. The crisis prompted international intervention, including a UN authorised mission, which retook northern cities within weeks. Islamist rebels retreated into civilian populations and remote areas.

    Despite these efforts, violence against civilians by extremist groups and community militias has continued. By 2023, 8.8 million Malians needed humanitarian assistance. Over 375,500 were internally displaced, primarily women and children.

    Meanwhile, the former French colony had turned to China for military assistance. Between 2012 and 2013, China provided €5 million (about US$5.8 million) in logistical equipment to improve the Malian army’s mobility.

    In August 2013, the Chinese People’s Liberation Army gave the Malian army military supplies totalling 1.6 billion CFA francs (about US$2.8 million). China made similar donations between 2014 and 2023.

    I am an international security and global governance researcher. My recent research explored the impact of China’s security sector assistance on Mali’s fragility.

    China’s assistance to Mali aims to equip the country to address terrorism and insurgency. But I argue that it may have unintended consequences and cause further damage to the country.

    The heavy reliance on Chinese supply exposes Mali to vulnerabilities, including supply disruptions, diminished bargaining power, and limited strategic flexibility. This could destabilise security even more should China face manufacturing issues or supply chain disruptions leading to delays or shortages in the production of weapons.

    It also raises concerns about the potential influence of China on Mali’s defence policies and decision-making processes. In turn this could entrench the Malian military government’s position. China takes a hands-off approach to the governance structures of the countries it engages with. Hopes of democratisation in the country could be affected.

    Rich in resources

    Mali has significant natural resources, including 800 tons of gold reserves (it’s Africa’s fourth-largest producer), iron ore, manganese, lithium, and potential uranium and hydrocarbon deposits.

    In 2019, gold production generated US$734 million, or 9.7% of Mali’s GDP, supporting over 10% of the population.

    Chinese firms, such as Ganfeng Lithium and China National Nuclear Corporation, have invested heavily in Mali’s mining sector. They are involved in a US$130 million lithium project and uranium exploration in the Kidal and Falea regions.

    Despite security risks, including attacks on Chinese personnel in 2015 and 2021, China remains committed due to Mali’s resource potential.

    Beyond mining, China has invested in Mali’s infrastructure. A US$2.7 billion railway modernisation project connects Bamako to Dakar, facilitating resource exports like iron ore and bauxite.

    The total of Mali’s external debt to China is not explicitly stated. But the 2014 loan agreement of US$11 billion and the 2016 loan of US$2.7 billion alone suggest Mali’s debt to China could be at least US$13 billion. This is without including loans for projects like the Bamako-Ségou expressway, and bridges in Bamako.

    This has often been criticised as “debt trap diplomacy”, increasing recipient countries’ dependence on Beijing. In Mali, I believe this risks entrenching economic vulnerability and giving China geopolitical leverage.

    China’s security sector assistance to Mali

    Historically, Mali relied on France. More recently, it’s used Russia’s expeditionary corps, formerly known as Wagner Group, for security support.

    In 2011, China provided US$11.4 million in grants, US$8.1 million in zero-interest loans, and a US$100.8 million concessional loan to foster bilateral cooperation.

    China’s participation in the United Nations Multidimensional Integrated Stabilisation Mission in Mali, starting in 2013 with 395 personnel, marked a shift in its security engagement.

    Chinese peacekeepers, including engineers, medical personnel and security guards, repaired infrastructure, provided medical aid and supported Mali’s 2013 elections.

    Their professionalism earned praise from the UN special envoy Albert Gerard Koenders for helping to ensure a smooth election.

    China’s involvement in Mali challenged traditional European approaches to peacekeeping, particularly France’s military-heavy strategy.

    How China’s assistance contributes to Mali’s fragility

    In spite of the positives, China’s security sector assistance contributes to Mali’s fragility in several ways.

    First, its no-strings-attached nature allows Mali’s military junta to consolidate power without making democratic or governance reforms.

    This lack of accountability enables corrupt military factions to operate unchecked. Governance weaknesses and authoritarianism can continue.

    Second, the heavy reliance on Chinese supply raises concerns about the potential influence of China on Mali’s defence decisions.

    This over-reliance on military solutions risks escalating conflicts and could lead to human rights abuses by security forces, as seen in increased violence against civilians. It doesn’t address root causes of conflict like social cohesion or local governance.

    Third, Mali’s growing dependence on Chinese aid — both military and economic — makes it vulnerable to disruptions from geopolitical tensions, supply chain issues, or changes in China’s foreign policy. This limits Mali’s ability to diversify its military capabilities or respond to evolving threats.

    Finally, China’s infrastructure investments, such as the US$1.48 billion (750 billion CFA francs) Bamako-Dakar railway loan, creates “debt trap diplomacy”.

    This pattern deepens economic dependence and reduces policy autonomy, further weakening state resilience.

    The way forward

    To mitigate the risks of Chinese security sector assistance and promote sustainable stability, Mali must adopt a multifaceted strategy.

    First, it should collaborate with China to align security sector assistance with civilian-led security approaches.

    Second, Mali should diversify security and economic partnerships with donors like the US, the UK, and the EU.

    Third, transparent guidelines, developed through consultation with stakeholders, should assess the impacts of assistance to avoid deepening dependence.

    Fourth, engaging civil society and publishing regular reports on security sector assistance use and outcomes will foster public trust.

    Finally, promoting regional economic integration and ties with global powers will bolster Mali’s economic resilience.

  • MIL-OSI Analysis: The use of federal troops to quell Los Angeles protests recalls militarized law enforcement during the Civil Rights Movement

    Source: The Conversation – USA – By Justin Randolph, Assistant Professor of U.S. History, Texas A&M University

    President Donald Trump activated 4,000 National Guard troops on June 10, 2025, to quell protests in Los Angeles over immigration raids – without the normal request from the state. He has also sent to Los Angeles hundreds of U.S. Marines, with the goal of protecting the unprecedented deportation operations by U.S. Immigration and Customs Enforcement.

    If this all feels exceptional, it should. Governors typically activate their own state troops, as Texas Gov. Greg Abbott said he would do on June 11 ahead of expected immigration protests.

    California quickly sued the president. A federal court has sided with the state, but an appeals court will weigh the Trump administration’s use of the U.S. code on armed services to activate the National Guard, which relies on protesters constituting either an “invasion” or “rebellion.”

    “What we’re witnessing is not law enforcement – it’s authoritarianism,”
    California Gov. Gavin Newsom said on June 10.

    Protesters report violent responses from Los Angeles police, too. Nonetheless, Newsom’s invocation of authoritarianism is apt.

    The last example of a president federalizing troops over the objection of a state government dates to Jim Crow segregation, a period marked by legal practices that routinely denied due process and citizenship rights to Black Americans in the South. In the 1960s, numerous Black freedom struggles took stands against this authoritarianism backed by militarized law enforcement.

    As a scholar of U.S. history, I’ve just completed a book on Jim Crow policing and the ways Black Americans fought back against racist law and order. I think the militarization of policing in Los Angeles opens important questions about democracy and state violence.

    Jim Crow dreams

    During the Civil Rights Movement, the federal government activated National Guard troops over Southern state objections when those states would neither enforce court orders nor protect protesters.

    In those cases, presidents protected people with the help of troops. In Trump’s case, he’s using troops to protect the government from protesters.

    The Trump administration’s vision of law enforcement aims for the type of militarized authority that state governments institutionalized under Jim Crow policing. If your political enemy is perceived more like an enemy combatant, the rules of legal procedure, especially due process, might not apply. Policing becomes war.

    When you see the words “Jim Crow,” your mind may jump to photos of racially segregated water fountains. But Jim Crow was far more than that. It was homegrown racial authoritarianism, or the repression of freedom of thought and action.

    Before troops enforced civil rights, Black Southerners saw the National Guard as an enemy rather than a friend.

    In the words of Ida B. Wells-Barnett after a white riot against Black residents in St. Louis, Missouri, in 1917, “The police were either indifferent or encouraged the barbarities. … The major part of the National Guard was indifferent or inactive. No organized effort was made to protect the Negroes or disperse the murdering groups.”

    Eisenhower sends in the troops

    The U.S. Supreme Court’s 1954 decision in Brown v. Board of Education changed things. It overturned the 1896 Plessy v. Ferguson decision that legalized racial segregation and ruled that segregated public school education was unconstitutional. This significantly altered the federal government’s responsibility in the South’s legal system of white supremacy.

    The first test came in Little Rock, Arkansas, in 1957. Though numerous school districts across the South quietly desegregated, Southern governors such as Arkansas’ Orville Faubus resisted the planned desegregation of Little Rock Central High School.

    Faubus deployed the Arkansas National Guard to stop Black children at the door. For nearly three weeks, Guardsmen blocked the small group of Black students – known as the “Little Rock Nine” – who were supposed to attend the school before President Dwight Eisenhower federalized the Arkansas National Guard and ordered them to stand down.

    Eisenhower deployed U.S. Army riot troops to Little Rock under the Insurrection Act. In the end, the Little Rock Nine began their studies at Central High despite the much-photographed spitting from the white mob that surrounded the school.

    State troops, state rights

    Next came the desegregation of interstate transportation.

    In spring 1961, the Congress of Racial Equality, a civil rights advocacy group, sent buses of integrated passengers through the Deep South. White terrorists attacked Freedom Riders, as these activists became known, three times in Alabama.

    But state authorities had learned from the Little Rock experience. Southern governors in Alabama and Mississippi deployed the National Guard themselves. This time they intended to only minimally protect Freedom Riders to block federal law enforcement. In Mississippi, police arrested and prison guards tortured Freedom Riders in the state penitentiary. Mob violence killed no one.

    The same was not true during the desegregation of public universities.

    When U.S. marshals arrived to enforce the court order enrolling James Meredith at the University of Mississippi in September 1962, a white riot erupted. State law enforcement withdrew from the scene. Two men died, and many more were injured.

    President John F. Kennedy federalized the Mississippi National Guard and sent them in to restore order. The next summer, he did the same in Tuscaloosa, Alabama, to preemptively halt a riot at the University of Alabama.

    The occasion became a publicity stunt for Alabama Gov. George C. Wallace. He temporarily blocked the entrance to Foster Auditorium, intent on stopping the court-ordered registration of three Black students.

    “I stand before you here today in place of thousands of other Alabamians whose presence would have confronted you,” Wallace said to federal authorities. A National Guard general said, “Sir, it is my sad duty to ask you to step aside under the orders of the President of the United States.”

    A National Guard general informs Alabama Gov. George C. Wallace that the guard was under federal control, as the two meet at Foster Auditorium at the University of Alabama in Tuscaloosa, Ala., on June 11, 1963.

    Wallace also triggered the last federal use – until now – of the National Guard. Alabama’s Selma-to-Montgomery march began as a memorial to Jimmie Lee Jackson, a young Black civil rights activist who was killed by police on Feb. 26, 1965. The march became primarily a symbol for the year’s Voting Rights Act.

    In an important change, President Lyndon B. Johnson federalized the National Guard to protect marchers. State troopers and sheriff’s deputies had terrorized marchers, including John Lewis, who was almost beaten to death on Bloody Sunday, March 7, 1965.

    Democracy is in the streets

    The history of the National Guard in the South is an important part of what’s unfolding in Los Angeles and across the nation.

    For most of the National Guard’s history in the South, political leaders used domestic military power to preserve the interests of racial authoritarians, not racial egalitarians. Little Rock, Tuscaloosa, Selma: Those moments when troops protected racial justice protesters at home stand out as some of America’s most hopeful moments.

    Recent statements by Trump administration officials help illustrate how it envisions using military power in domestic law enforcement. On June 8, 2025, Homeland Security Secretary Kristi Noem asked Defense Secretary Pete Hegseth “to arrest rioters” – a request beyond the original order to protect ICE agents.

    And on June 12, Noem said that “the military people that are working on this operation … are staying here to liberate the city from the socialist and burdensome leadership that this governor and that this mayor have placed on this country.”

    The National Guard and Marines are reportedly protecting immigration enforcement. But what might happen if they directly interact with protests?

    With diverse tactics, protesters are halting business as usual because they see a mass-deportation regime terrorizing and disappearing people in their communities. U.S. courts tend to agree with their analysis but seem powerless to enforce even basic due process rights for those detained by ICE.

    These activists show the messy work of American social change. Their work may look like “anarchy” to even some Democrats. It may be maligned as “invasion” and “rebellion” by the Trump administration.

    But the calls to constrain ICE follow an American tradition of fighting authoritarianism.

  • MIL-OSI Analysis: Lower revenues, pricier loans: how flooding in Europe affects firms and the financial system they depend on

    Source: The Conversation – France – By Serena Fatica, Principal Economist — Team Leader, Joint Research Centre (JRC)

    In Europe, the fastest-warming continent, the intensification of extreme weather events and changes in precipitation patterns have led to widespread and catastrophic flooding. Last year, storms and flooding affected an estimated 413,000 people, resulting in the loss of at least 335 lives. Material damage is estimated to amount to at least €18 billion, according to the 2024 European State of the Climate report from the Copernicus Climate Change Service and the World Meteorological Organization.

    The flooding in October that hit southeastern Spain and the Valencia province in particular took the heaviest toll. Intense and prolonged rainfall and river flooding led to 232 fatalities, and infrastructure damage and economic losses totalled around €16.5 billion. More than seven months later, the local economy has rebounded, thanks in part to public aid packages worth 0.5% of the country’s GDP. However, in early May, the same part of Spain found itself exposed again to the disruptive consequences of climate change when extreme weather hit.

    The costs of flooding

    The direct costs from the damage to public infrastructure and private assets are only part of the economic losses originating from flooding. The indirect costs might not be immediately visible, but they are certainly not less significant. Business interruptions reduce firms’ revenue and cash flows, straining liquidity and, in the worst cases, threatening their survival. In addition, the increasing likelihood of future flooding may be priced into the valuation of assets and real estate in areas exposed to these types of climate risks. Firms impacted by climate-related hazards might find it difficult to pay back loans or bonds, or to raise finance as physical assets that can be pledged as collateral for bank credit lose value. Ultimately, this can affect the stability of the financial system.

    For these reasons, climate change is not just a long-term environmental issue, but a threat to our economy and financial systems now. Economists at the European Commission’s Joint Research Centre (JRC) have been conducting research to better understand how the links between the business sector and the financial system amplify its impact.

    A JRC study of flood events between 2007 and 2018 finds that flooding significantly worsened the performance of European firms. Manufacturers exposed to flooding experienced reductions in sales, number of employees and the value of their assets. These impacts occurred in the year following the flooding and tended to be persistent, with no clear signs of recovery seven years after the disaster. Some firms even went out of business. The study also finds that companies in flood-prone areas were better able to weather the shock than businesses exposed to less frequent flooding. This is consistent with the fact that adaptation and protection measures reduce the impacts of flooding.

    Threats to smaller firms

    Water damage is particularly disruptive for companies that are highly indebted. A second JRC study zooms in on the mechanisms whereby financing choices, and reliance on bank loans in particular, amplify the impact of climate change. This study focuses on loans extended to small and medium-sized enterprises (SMEs) in Italy, Spain and Belgium between 2008 and 2019. It was motivated by the idea that smaller firms, which are more financially fragile than larger ones, might also be more vulnerable to the localised impact of climate-related hazards, not least because of their limited capacity to geographically diversify their operations and access market-based finance. The study shows that flood episodes under analysis strained SMEs’ ability to meet their debt obligations. Flooded firms were more likely to incur delays in servicing their loans and eventually fail to repay them, even two years after the disaster.

    In turn, this entails losses for the banks that finance these firms. In general, if banks anticipate the impact of flooding on business operations, they could be expected to divert lending toward safer borrowers or charge a higher interest rate on credit extended to at-risk firms. Indeed, the study finds evidence that prospective flood risk is priced into new loans. In the period under analysis, the “flood risk premium” was especially high for loans to smaller firms and for those granted by local, specialised banks, both of which tend to have geographically concentrated activities that are more exposed to disaster impacts. Loans to borrowers exposed to high flood risk were 12 percent more expensive, all things being equal.

    Thus, flooding causes worse financial conditions for businesses and exposes the banking sector to losses on their loan portfolios. The numbers can be staggering: days after the October 2024 flooding, the Spanish Central Bank said that banks’ exposure in the affected areas would total €20 billion, with €13 billion in household loans and €7 billion in business loans (60% to SMEs), impacting 23,000 companies and 472,000 individuals.

    With extreme weather events becoming more frequent and severe, the direct and indirect costs of climate change are projected to increase, unevenly affecting households, firms and territories across Europe. Increasing investments in adaptation, eg in flood defence, and closing the climate insurance protection gap – the uninsured portion of economic losses caused by natural hazards – are crucial to increase the resilience of our economies and financial systems and preserve the wellbeing of our societies. The complex structure of investment incentives calls for a multilayered approach, with a mix of private and public funding and risk-sharing mechanisms.

    MIL OSI Analysis –

  • MIL-OSI Analysis: Israeli aggression and Iranian nuclear brinkmanship made this confrontation all but inevitable

    Source: The Conversation – UK – By Matthew Moran, Professor of International Security, King’s College London

    In the early hours of June 13, Israel launched its largest-ever attack on Iran. Airstrikes involving more than 200 aircraft targeted nuclear and missile facilities, as well as key figures in the Iranian military and nuclear programme leadership. The attack, codenamed “Operation Rising Lion”, appears to have been supported on the ground by Israeli agents operating drones positioned deep within Iranian territory.

    In one sense, this attack has been a long time coming. Over the past 15 years, Israel has repeatedly threatened to attack Iran, arguing that Tehran harbours nuclear weapons aspirations that pose an existential threat to the Israeli state. Israel’s prime minister, Benjamin Netanyahu, said as much in a televised address announcing the same-day military operation in which he placed the nuclear issue front and centre: “We struck at the heart of Iran’s nuclear weaponisation program.” But why has Israel chosen to act now?

    Clearly, we are looking at a dynamic situation from the outside in, but there are some important points worth considering. First, events over the past 12 months or so have undermined Iran’s ability to deter adversaries, which has left the regime exposed. Israel’s response to an Iranian missile attack in October, for example, seriously degraded Iran’s air defences as well as missile production capabilities. This created weaknesses that Israel has since exploited in its renewed military campaign.

    Looking more broadly, the fallout from the October 7 attack by Hamas on Israel has decimated the proxies that Iran spent decades cultivating in the Middle East. The brutal war in Gaza has decimated Hamas, while to the north, Hezbollah is severely degraded after its own 14-month war with Israel.

    Add to this the fall of the Assad regime in Syria, and it is clear that Iran’s so called “axis of resistance”, a key pillar of the country’s deterrence posture, is now a dramatically reduced force. Israel has been emboldened by these events. It now clearly sees a unique opportunity to further degrade a major adversary – and potentially bring about regime change.

    What’s more, Iran’s nuclear programme has continued to advance since Donald Trump withdrew the US in 2018 from the joint comprehensive plan of action (JCPOA). This was the 2015 deal negotiated during Barack Obama’s presidency that rolled back the country’s nuclear capabilities in return for a relaxation of harsh sanctions against Iran.

    In March, the Washington-based – but non-partisan – Institute for Science and International Security reported that Iran could convert its current stock of 60% enriched uranium into enough weapons-grade uranium for seven nuclear weapons at the Fordow fuel enrichment plant. This could be done in as little as three weeks.

    At the same time, the US director of national intelligence, Tulsi Gabbard, told the Senate intelligence committee on March 27 that the intelligence community “continues to assess that Iran is not building a nuclear weapon”.

    So this raises the question of whether the Israeli government had intelligence that the Iranians were moving forward with weaponisation. It is possible that Iran was preparing to make a dash for the bomb, crossing an Israeli red line and triggering action – although there is currently no evidence to support this theory. What is clear, however, is that Iran’s brinkmanship around its effort to hedge its bets on a nuclear option meant it was always operating in a dangerous space.

    Was the Israeli attack inevitable?

    At first sight, the answer to this seems obvious. For years now, Israel has been very clear that it will not accept a nuclear armed Iran. Yet Tehran has insisted on a nuclear programme that appears to go well beyond what is required for civil nuclear purposes. On June 12, the International Atomic Energy Agency declared that Iran was not complying with its nuclear safeguards obligations.

    By most estimates, Iran is not far from the bomb and Israel has finally taken action – ostensibly on this basis.

    Had Iran curbed its nuclear advancement and continued to comply with its IAEA obligations, Israel would have found it more challenging to justify any military action politically. In the same vein, if Iran had made quicker and greater progress in its nuclear talks with the Trump administration on reaching some form of new deal, this would also have made it more difficult for Israel to act.

    The combination of the IAEA declaration and the lack of acceptable progress in talks with the US clearly influenced Israeli decision making. So why did the Iranian regime not take more concrete steps in this direction?

    Iran’s nuclear ‘hedging’

    The answer goes to the heart of Iran’s deterrence posture. Alongside its conventional forces and its infamous axis of resistance, Iran has sought to leverage its nuclear programme for influence.

    Nearly ten years ago, we argued that Iran was engaged in a strategy of “nuclear hedging”. The value of this approach lies in the potential for a state to position itself relatively close to the bomb without incurring all the negative – including potentially military – consequences of a fully-fledged nuclear weapons programme, where the goal is to cross the threshold as quickly as possible.

    Yet hedging is a delicate balancing act that requires plausible deniability of weapons intent. A step too far can undermine any idea that the nuclear development is for civilian use, instead inviting military intervention.

    Conversely, too few steps towards a credible breakout capability and hedging has little value. For any coercive or deterrent benefit to be obtained, a state must be perceived by others as relatively close to having the bomb.

    With the deterioration of Iran’s regional power over the past year, the value to Tehran of its nuclear programme has become much greater. This may help to explain why Iran did not take firm steps to reduce external concerns about its nuclear intentions.

    Tehran is likely to have factored the cost of being seen to give in to external pressure on its nuclear programme. At home there is the risk that the regime’s hold on power could be weakened by capitulation to external pressure from the US, and Israel in particular. Regionally, the power costs would include losing valuable influence over other states across the Middle East.

    At the same time, the US government has changed its stance since the JCPOA deal was struck during Obama’s presidency in 2015, allowing Iran some small degree of enrichment capacity. The first Trump administration pulled the US out of the JCPOA in 2018 depicting it as a flawed agreement.

    In Donald Trump’s second term, his administration has continued to take a hard line, pushing for Iran to give up enrichment. From an Iranian perspective, the benefits of rolling back its capabilities failed to materialise.

    This is a rapidly evolving situation. But even at this early stage, this case demonstrates clearly the risks associated with Iran’s strategy of nuclear hedging.

  • MIL-OSI Analysis: Israel’s air strength is giving it a free hand over Iran

    Source: The Conversation – UK – By Matthew Powell, Teaching Fellow in Strategic and Air Power Studies, University of Portsmouth

    Israel’s initial attack on Iranian nuclear and military facilities, alongside its assassination of top military officials and nuclear scientists, on June 13 has been followed by days of escalating strikes. Iran threatened “severe punishment” and quickly launched what were, in relative terms, smaller-scale missile attacks against Israeli territory.

    Israel’s military then expanded its assault on Iran, with the Israeli defence minister, Israel Katz, saying “Tehran will burn” if Iran’s supreme leader, Ayatollah Ali Khamenei, “continues to fire missiles at the Israeli home front”. Israel hit dozens of targets in the Iranian capital, Tehran, on June 15, and has since issued evacuation orders for significant areas of the city.

    The exchange of attacks has put the varying military and defensive capabilities of Israel and Iran on stark display. In particular, it appears that Israel has been able to exercise a high degree of air superiority over Iran.

    Israel was able to use more than 200 manned aircraft in its initial attack, with its air force reportedly suffering zero casualties. Within 48 hours of starting the conflict, Israel said it had gained control of the skies above Tehran.

    Get your news from actual experts, straight to your inbox. Sign up to our daily newsletter to receive all The Conversation UK’s latest coverage of news and research, from politics and business to the arts and sciences.

    This superiority has largely been gained through concerted efforts over the past year to destroy or degrade Iran’s air defence systems. In October 2024, for example, Israeli strikes targeted air defences protecting Iranian oil and gas facilities as well as those defending sites linked to Tehran’s nuclear programme and ballistic missile production.

    With a weakened air defence system, the Iranian military has been less able to prevent missile attacks and Israeli aircraft from entering its air space. This has given the Israeli military greater freedom of action in terms of the targets it chooses to attack – and greater freedom of choice when planning operations.

    Israeli aircraft have been dropping bombs from within Iran, instead of relying on long-range missiles. Iran, on the other hand, has been restricted to using its arsenal of missiles to strike Israel from distance.

    Israel’s prime minister, Benjamin Netanyahu, made reference to the strategic importance of this aerial superiority on June 16. While confirming evacuation orders for the Iranian capital, he said: “The Israeli air force controls the skies over Tehran. This changes the entire campaign.”

    Netanyahu later did not rule out killing Khamenei, saying it would “end the conflict”. Katz repeated the threat the following day, warning Khamenei of a “fate similar to Saddam Hussein”.

    Iran has been far less effective than Israel in its response – which is no great surprise. Israel says it has destroyed “one-third” of the surface-to-surface missile launchers possessed by Iran. And the majority of the missiles and drones that have been fired by Iran into Israeli territory have been intercepted before striking their targets.

    But the strength of Israel’s so-called iron dome air defence system has, somewhat counter-intuitively, also offered Iran some advantages. In order to maintain the Iranian regime’s own internal security and stability, as well as its wider political aims of being a regional power, Tehran had to respond with a certain level of force.

    However, Iran is also fully aware of the protection the iron dome provides to the Israeli population. The Iranian government will still be able to point to the few missiles and drones that have reached their target, and the destruction they have caused, as evidence that it is able to project its power beyond its own borders and respond in the face of aggressive Israeli action.

    It is able to do so in the knowledge that the level of destruction and deaths of Israeli civilians, which so far stands at around 24 people, will be limited to such a degree that any further escalation by Israel will be seen as unjustified by the wider international community.

    However, as the destruction and death toll rises, it will become harder for either government to follow this path of logic. Iran has already criticised the Israeli military’s claim that it has conducted strikes in a precise manner and only against military targets, reporting that over 200 civilians have been killed in the strikes.

    It is here where mistakes and missteps could see events spiral out of control. This may lead to a wider and larger-scale conflict that neither side wants but is unable to prevent occurring. Iran, for its part, is reportedly signalling that it is seeking an end to hostilities and the resumption of talks over its nuclear programme.

    Wider consequences

    If the conflict does escalate, Israel will probably target Iranian military production facilities. The Israeli military has already issued a warning on social media, telling the Iranian people to stay away from all weapons manufacturing facilities.

    Other targets may include nuclear installations – though at least one, the heavily fortified Fordow nuclear site in central Iran, will not be targeted. Fordow is hidden in a mountain, with centrifuges located possibly as deep as 80 metres underground.

    Only the US military has the hardware capable of reaching this facility, so attacking the site would require US intervention. This is something the current Washington administration has proved reluctant to do, so far.

    But any escalation could have ramifications beyond the Middle East. Iran has supplied Shahed-type drones to Russia for use in its war in Ukraine, with them becoming a key part of Russia’s military strategy. However, Russia is now largely producing its own supplies of Shahed drones internally.

    A much more likely effect is the prolonging of the war in Ukraine as international attention shifts to de-escalating tensions between Israel and Iran. The international community has focused on trying to prevent further attacks, with the US president, Donald Trump, advocating for talks rather than more strikes.

    On June 15, Trump wrote on his social media platform, Truth Social: “Iran and Israel should make a deal, and will make a deal, just like I got India and Pakistan to make.” Whether Israel and Iran take heed of his request will become clear over the coming days and weeks.

  • MIL-OSI Analysis: Could faecal transplants cause long-term health problems?

    Source: The Conversation – UK – By Georgios Efthimiou, Lecturer in Microbiology, University of Hull

    Getting ready to make some poo pills. microgen/Shutterstock.com

    Keeping a healthy mix of friendly microbes in the gut – known as eubiosis – is crucial for good health. When that delicate balance is thrown off – often by antibiotics, diet or illness – the result can be a range of issues, from digestive problems to more serious conditions like Crohn’s disease, ulcerative colitis, and even neurological and metabolic disorders.

    One increasingly popular way to try to restore gut health is through faecal microbiota transplantation. This involves taking stool from a healthy person, isolating the beneficial microbes and putting them in a capsule (jokingly referred to as “crapsules” or “poo pills”). The hope is that the beneficial microbes in the pill will establish themselves in the patient’s gut, thereby improving microbial diversity and function.

    Faecal transplants have been used to treat a wide array of conditions, including irritable bowel syndrome, Parkinson’s disease, obesity and Type 2 diabetes.

    Although generally viewed as safe and effective, a new international study published in the journal Cell has raised some concerns. The scientists found that when the donor’s microbes do not properly match the recipient’s gut environment – a situation they describe as a “mismatch” – the treatment can disrupt the body’s metabolic and immune systems, possibly with long-lasting consequences.

    The term “mismatch” comes from the world of organ transplants, where the recipient’s body rejects the donor organ. In this case, the problem is that microbes from the donor’s large intestine may not be suitable for other parts of the recipient’s gut, especially the small intestine, where the microbial makeup is very different.

    To test this, researchers gave antibiotics to mice to disturb their natural gut microbes, then treated them with faecal transplants. They also tried transplanting microbes specifically from different parts of the small intestine. The mice were monitored for one to three months to track changes.

    Wrong microbes in the wrong place

    They found that faecal transplants often led to regional mismatches – the wrong microbes ending up in the wrong place. This altered the mix and behaviour of the gut microbes in unexpected ways, disrupting energy balance and other functions.

    Biopsies from the gut and liver showed significant, lasting changes in how certain genes – particularly those linked to metabolism and immunity – were being expressed.

    The study did not specify exactly what kind of health issues might result from these genetic shifts. But the researchers are urging doctors to take greater care when using faecal transplants, particularly when it comes to dose, timing and possible side-effects.

    There may, however, be a better way forward. A newer method known as the “omni microbial approach” involves transferring microbes from all parts of the intestine, not just the colon. This could help recreate a more balanced and natural gut environment, avoiding the local mismatches seen in standard faecal transplants.

    There is also growing interest in techniques that aim to “terraform” the gut: deliberately reshaping specific regions with carefully selected microbes to restore normal function.

    This new research has certainly sparked debate around the safety of faecal transplants. But with alternative approaches already being developed, there is real hope that the benefits of gut-based treatments can still be delivered, without the risks.

  • MIL-OSI Analysis: Declining soil health is a global concern – here’s how AI could help

    One-third of the Earth’s land surface is already degraded. The UN estimates that more than 2.6 billion people are harmed by land degradation, with countries losing up to US$10.6 trillion (£7.8 trillion) a year because of damage to “ecosystem services”, including the benefits people get from nature such as water and food.

    Unhealthy soil is a major contributor to land degradation. This can lead to loss of biodiversity, harm plants and animals, cause sand and dust storms and affect crop yields.

    These consequences affect the regulation of the planet’s climate and water cycle, socioeconomic activities, food security and forced migration of people.

    Emerging smart technologies such as artificial intelligence, satellite remote sensing and big data analysis offer a chance to protect our soils. These tools can help track soil health in real time. This will support farmers, landowners, government agencies and local communities in making better decisions to care for the soil.

    As a professor of geo-hydroinformatics – a field that combines geoscience, hydrology and information technology – my research focuses on using AI, algorithms and advanced modelling tools to better analyse and predict soil health.

    My team and I have developed the first global map of soil salinisation (accumulation of salt in soil) under various climate scenarios using AI-powered techniques. Soil salinisation is one of the leading contributors to soil degradation and can happen naturally or because of human activities, such as using salty irrigation water or poor drainage systems.

    With increasing climate uncertainty, our models help identify regions most vulnerable to salinisation. Our AI-driven analysis predicts that by the year 2100, dryland regions in South America, southern and western Australia, Mexico, the southwestern US and South Africa will be key hotspots of soil salinisation.

    In another key study, we used satellite data, AI and big data tools to investigate the interaction between soil salinity and soil organic carbon – an important part of healthy soil that stores nutrients, holds water and supports plants.

    Part of this analysis revealed a general negative correlation between salinity levels and soil organic carbon content. As salinity increased, we found that the soil organic carbon content tended to decrease.

    Our two studies underscore the transformative potential of AI technologies and big data analytics in understanding soil degradation. With a deeper understanding, land can be better managed through more effective mitigation policies and sustainable land use planning.

    Restoration at scale

    Large-scale land restoration can transform degraded soils. In the Loess plateau in China, centuries of deforestation and unsustainable farming have led to significant ecological challenges. Loess soils (a type not limited to this location in China, formed essentially by the accumulation of wind-blown dust) are easily eroded because they are made up of fine and loose particles.

    Degradation here has led to more frequent floods, droughts and dust storms because soil degradation is often associated with compaction. This reduces the ability of soil to absorb and hold water.

    In the 1990s, this prompted the Chinese government to invest in reforestation and sustainable agriculture. This led to the landmark Loess plateau watershed rehabilitation project, with the main goal of boosting farming and incomes on 15,600km² of land in the Yellow River’s tributary area. The total project cost of US$150 million, partly funded by the World Bank, was approved in 1994.

    Elsewhere, in the Tigray region of Ethiopia, the EthioTrees project was launched in 2016 to tackle land degradation through community-based reforestation, enclosures to limit grazing, and reinvestment of funds generated through climate finance mechanisms.

    Tree planting and other efforts have transformed the Tigray region of Ethiopia into a more fertile landscape.

    Despite challenges including drought and limited financial resources, these large-scale restoration projects have transformed the landscape and lives of people living there.

    But the Loess plateau and Tigray projects have been complex and expensive. A lot of coordination between people across huge regions and in different sectors is required to ensure a successful, integrated approach. AI can take these successful but resource-intensive restoration efforts and help scale them up.

    I’m also involved with a European Commission-funded project called AI4SoilHealth, which aims to advance the use of AI to monitor and quantify soil health across Europe. This project shows how data-driven initiatives can support more sustainable land management policies by providing timely, actionable information to governments, farmers and other stakeholders such as landowners, agribusiness companies and local communities.

    By integrating satellite imagery with accurate data about soil properties in different locations, AI can help develop robust, scalable models that cross local boundaries. Knowing where best to invest money, resources and effort in scaling up soil health solutions will help protect people, businesses and ecosystems from extreme events in the future.

  • MIL-OSI Analysis: The Inca string code that reveals Peru’s climate history

    Source: The Conversation – UK – By Sabine Hyland, Professor of Social Anthropology, University of St Andrews

    Five centuries ago, the Incas ruled the western half of South America with the help of a unique form of writing based on coloured and knotted cords. These strings, called khipus, recorded major events, tracked economic matters, and even encoded biographies and poetry, according to the Spanish chroniclers who witnessed their use.

    Most khipus have knots that indicate numbers that we can “read”, but we’ve lost the ability to interpret what those numbers mean. Recent discoveries are bringing us closer to deciphering these mysterious strings. In a remote community set high in the Peruvian Andes, my team and I have found khipus that were used by villagers to track climate change.

    Last year, I was invited to study the centuries-old khipus preserved in the village of Santa Leonor de Jucul in the Peruvian Andes. The 97 khipus conserved by villagers include the largest khipu in the world, which is over 68 metres long.

    An elderly ritual specialist, Don Lenin Margarito, told me that the khipus recorded the annual ritual offerings given at different sacred places in the surrounding landscape. Miniature pink ritual bags stuffed with coca leaves and tobacco hang from the cords, representing the sacred purpose of these ancient strings. Rather than communicating through knots, the Jucul khipus record data with different kinds of tassels.

    For example, a tassel made of fuzzy beige llama tails indicates that an offering was performed at the sacred lake of Paccha-cocha, high in the mountains. The fluffiness of the llama tails is like a rain cloud, Don Lenin explained, representing the fact that offerings given at Paccha-cocha are thought to bring rain.

    Different kinds of tassels indicate offerings made at other ritual sites, each one of which is thought to have its own effect on the local environment. Rituals involving the spirits of the dead, for instance, are thought to halt flooding.

    If you look at one of the Jucul khipus and you see that there were a lot of offerings to Paccha-cocha that year, you know that this was a time of drought since the offerings were given to increase the rain.

    When speaking with community members, we learned that the khipus used to be kept in public so that they could be consulted by the elders. Andean people of the past looked at these khipus as a record of the climate, and they studied them to understand the patterns of what was going on, just as we do today.

    New methods

    New methods for obtaining precise radiocarbon dates for khipus have been pioneered by a team headed by khipu researcher Ivan Ghezzi.

    Efforts are now underway to get accurate radiocarbon dates for the Jucul khipus, which will provide a chronology of these climate-based offerings.

    If we can chart the khipus and then date them, we will have a record of climate data from this region that was created by the local Andean people themselves. In their current state, the Jucul khipus are threatened by insects, mould and rodents. The British Museum recently granted funding to clean, preserve and display the khipus so that these precious objects from the Andean past will persevere into the future.

    There are only five villages in the Peruvian Andes where ancestral khipus are kept. These rare archives offer tantalising clues about how khipus encoded information.

    Research in other villages with living khipu traditions has led to breakthroughs in the significance of khipu colour patterns and phonology. Many Inka khipus possess tassels which we believe may reveal the subject matter of the associated khipu. If we could unlock the significance of the tassels on the Jucul khipus, it might allow us to interpret more precisely the meaning of Inca cords.

  • MIL-OSI Analysis: When developing countries band together, lifesaving drugs become cheaper and easier to buy − with trade-offs

    Source: The Conversation – USA – By Lucy Xiaolu Wang, Assistant Professor, Department of Resource Economics, UMass Amherst

    Pooling procurement of drugs could increase the availability of essential treatments around the globe. narvo vexar/iStock via Getty Images Plus

    Procuring lifesaving drugs is a daunting challenge in many low- and middle-income countries. Essential treatments are often neither available nor affordable in these nations, even decades after the drugs entered the market.

    Prospective buyers from these countries face a patent thicket, where a single drug may be covered by hundreds of patents. This makes it costly and legally difficult to secure licensing rights for manufacturing.

    These buyers also face a complex and often fragile supply chain. Many major pharmaceutical firms have little incentive to sell their products in unprofitable markets. Quality assurance adds another layer of complexity, with substandard and counterfeit drugs widespread in many of these countries.

    Organizations such as the United Nations-backed Medicines Patent Pool have effectively increased the supply of generic versions of patented drugs. But the problems go beyond patents or manufacturing – how medicines are bought are also crucially important. Buyers for low- and middle-income countries are often health ministries and community organizations on tight budgets that have to negotiate with sellers that may have substantial market power and far more experience.

    We are economists who study how to increase access to drugs across the globe. Our research found that while pooling orders for essential medicines can help drive down costs and ensure a steady supply to low- and middle-income countries, there are trade-offs that require flexibility and early planning to address.

    Understanding these trade-offs can help countries better prepare for future health emergencies and treat chronic conditions.

    Pooled procurement reduces drug costs

    One strategy low-income countries are increasingly adopting to improve treatment access is “pooled procurement.” That’s when multiple buyers coordinate purchases to strengthen their collective bargaining power and reduce prices for essential medicines. For example, pooling can help buyers meet the minimum batch size requirements some suppliers impose that countries purchasing individually may not satisfy.

    Compared with decentralized procurement, pooled procurement eases transactions by connecting buyers and sellers in groups.
    Lucy Xiaolu Wang and Nahim Bin Zahur, CC BY-NC-ND

    Countries typically rely on four models for pooled drug procurement:

    • One method, called decentralized procurement, involves buyers purchasing directly from manufacturers.

    • Another method, called international pooled procurement, involves going through international institutions such as the Global Fund’s Pooled Procurement Mechanism or the United Nations.

    • Countries may also purchase prescription drugs through their own central medical stores, which are government-run or semi-autonomous agencies that procure, store and distribute medicines on behalf of national health systems. This method is called centralized domestic procurement.

    • Finally, countries can also go through independent nonprofits, foundations, nongovernmental organizations and private wholesalers.

    We wanted to understand how different procurement methods affect the cost of and time it takes to deliver drugs for HIV/AIDS, malaria and tuberculosis, because those three infectious diseases account for a large share of deaths and cases worldwide. So we analyzed over 39,000 drug procurement transactions across 106 countries between 2007 and 2017 that were funded by the Global Fund, the largest multilateral funder of HIV/AIDS programs worldwide.

    We found that pooled procurement through international institutions reduced prices by 13% to 20% compared with directly buying from drug manufacturers. Smaller buyers and those purchasing drugs produced by only a small number of manufacturers saw the greatest savings. In comparison, purchasing through domestic pooling offered less consistent savings, with larger buyers seeing greater price advantages.

    The Global Fund and the United Nations were especially effective at lowering the prices of older, off-patent drugs.

    Trade-offs with pooled procurements

    Cost savings from pooled drug procurement may come with trade-offs.

    While the Global Fund reduced unexpected delivery delays by 28%, it required buyers to place orders much earlier. This results in longer anticipated procurement lead time between ordering and delivery – an average of 114 days more than that of direct purchases. In contrast, domestic pooled procurement shortened lead times by over a month.

    Our results suggest a core tension: Pooled procurement improves prices and reliability but can reduce flexibility. Organizations that facilitate pooled procurement tend to prioritize medicines that can be bought at high volume, limiting the availability of other types of drugs. Additionally, the longer lead times may not be suitable for emergency situations.

    With the spread of COVID-19, several large armed conflicts and tariff wars, governments have become increasingly aware of the fragility of the global supply chain. Some countries, such as Kenya, have sought to reduce their dependence on international pooling since 2005 by investing in domestic procurement.

    But a shift toward domestic self-sufficiency is a slow and difficult process due to challenges with quality assurance and large-scale manufacturing. It may also weaken international pooled systems, which rely on broad participation to negotiate better terms with suppliers.

    Scaling up drug production in low-income countries can be difficult.

    Interestingly, we found little evidence that international pooled procurement influences pricing for the U.S. President’s Emergency Plan for AIDS Relief, a major purchaser of HIV treatments for developing countries. PEPFAR-eligible products do not appear to benefit more from international pooled procurement than noneligible ones.

    However, domestic procurement institutions were able to secure lower prices for PEPFAR-eligible products. This suggests that the presence of a large donor such as PEPFAR can cut costs, particularly when countries manage procurement internally.

    USAID cuts and global drug access

    While international organizations such as the Medicines Patent Pool and the Global Fund can address upstream barriers such as patents and procurement in the global drug supply chain, other institutions are essential for ensuring that medicines actually reach patients.

    The U.S. Agency for International Development had played a significant role in delivering HIV treatment abroad through PEPFAR. The Trump administration’s decision in February 2025 to cut over 90% of USAID’s foreign aid contracts amounted to a US$60 billion reduction in overall U.S. assistance globally. An estimated hundreds of thousands of deaths are already happening, and millions more will likely die.

    The World Health Organization warned that eight countries, including Haiti, Kenya, Nigeria and Ukraine, could soon run out of HIV treatments due to these aid cuts. In South Africa, HIV services have already been scaled back, with reports of mass layoffs of health workers and HIV clinic closures. These downstream cracks can undercut the gains from efforts to make procuring drugs more accessible if the drugs can’t reach patients.

    Because HIV, tuberculosis and malaria often share the same treatment infrastructure – including drug procurement and distribution networks, laboratory systems, data collection, health workers and community-based services – disruption in the management of one disease can ripple across the others. Researchers have warned of a broader unraveling of progress across these infectious diseases, describing the fallout as a potential “bloodbath” in the global HIV response.

    Research shows that supporting access to treatments around the world doesn’t just save lives abroad. It also helps prevent the next global health crisis from reaching America’s doorstep.

  • MIL-OSI Analysis: Companies haven’t stopped hiring, but they’re more cautious, according to the 2025 College Hiring Outlook Report

    Source: The Conversation – USA – By Murugan Anandarajan, Professor of Decision Sciences and Management Information Systems, Drexel University

    Recent college grads face a tough job market in 2025, but employers are still hiring. sturti/E+ via Getty Images

    Every year, I tell my students in my business analytics class the same thing: “Don’t just apply for a job. Audition for it.”

    This advice seems particularly relevant this year. In today’s turbulent economy, companies are still hiring, but they’re doing it a bit more carefully. More places are offering candidates short-term work experiences like internships and co-op programs in order to evaluate them before making them full-time offers.

    This is just one of the findings of the 2025 College Hiring Outlook Report. This annual report tracks trends in the job market and offers valuable insights for both job seekers and employers. It is based on a national survey conducted in September 2024, with responses from 1,322 employers spanning all major industries and company sizes, from small firms to large enterprises. The survey looks at employer perspectives on entry-level hiring trends, skills demand and talent development strategies.

    I am a professor of information systems at Drexel University’s LeBow College of Business in Philadelphia, and I co-authored this report along with a team of colleagues at the Center for Career Readiness.

    Here’s what we found:

    Employers are rethinking talent pipelines

    Only 21% of the 1,322 employers we surveyed rated the current college hiring market as “excellent” or “very good,” which is a dramatic drop from 61% in 2023. This indicates that companies are becoming increasingly cautious about how they recruit and select new talent.

    While confidence in full-time hiring has declined, employers are not stepping away from hiring altogether. Instead, they’re shifting to paid and unpaid internships, co-ops and contract-to-hire roles as a less risky route to identify talent and “de-risk” full-time hiring.

    Employers we surveyed described internships as a cost-effective talent pipeline, and 70% told us they plan to maintain or increase their co-op and intern hiring in 2025. At a time when many companies are tightening their belts, hiring someone who’s already proved themselves saves on onboarding reduces turnover and minimizes potentially costly mishires.

    For job seekers, this makes every internship or short-term role more than a foot in the door. It’s an extended audition. Even with the general market looking unstable, interest in co-op and internship programs appears steady, especially among recent graduates facing fewer full-time opportunities.

    These programs aren’t just about trying out a job. They let employers see if a candidate shows initiative, good judgment and the ability to work well on a team, which we found are traits employers value even more than technical skills.

    What employers want

    We found that employers increasingly prioritize self-management skills like adaptability, ethical reasoning and communication over technical skills such as digital literacy and cybersecurity. Employers are paying attention to how candidates behave during internships, how they take feedback, and whether they bring the mindset needed to grow with the company.

    This reflects what I have observed in classrooms and in conversations with hiring managers: Credentials matter, but what truly sets candidates apart is how they present themselves and what they contribute to a company.

    Based on co-op and internship data we’ve collected at Drexel, however, many students continue to believe that technical proficiency is the key to getting a job.

    In my opinion, this disconnect reveals a critical gap in expectations: While students focus on hard skills to differentiate themselves, employers are looking for the human skills that indicate long-term potential, resilience and professionalism. This is especially true in the face of economic uncertainty and the ambiguous, fast-changing nature of today’s workplace.

    Technology is changing how hiring happens

    Employers also told us that artificial intelligence is now central to how both applicants and employers navigate the hiring process.

    Some companies are increasingly using AI-powered platforms to transform their hiring processes. For example, Children’s Hospital of Philadelphia uses platforms like HireVue to conduct asynchronous video interviews. HR-focused firms like Phenom and JJ Staffing Services also leverage technologies such as AI-based resume ranking, automated interview scheduling and one-way video assessments.

    Not only do these tools speed up the hiring process, but they also reshape how employers and candidates interact. In our survey, large employers said they are increasingly relying on AI tools like resume screeners and one-way video interviews to manage large numbers of job applicants. As a result, the candidate’s presence, clarity in communication and authenticity are being evaluated even before a human recruiter becomes involved.

    At the same time, job seekers are using generative AI tools to write cover letters, practice interviews or reformat resumes. These tools can help with preparation, but overreliance on them can backfire. Employers want authenticity, and many employers we surveyed mentioned they notice when applications seem overly robotic.

    In my experience as a professor, the key is teaching students to use AI to enhance their effort and not replace it. I encourage them to leverage AI tools but always emphasize that the final output and the impression it makes should reflect their own thinking and professionalism. The bottom line is that hiring is still a human decision, and the personal impression you make matters.

    This isn’t just about new grads

    While our research focuses on early-career hiring, these findings apply to other audiences as well, such as career changers, returning professionals and even mid-career workers. These workers are increasingly being evaluated on their adaptability, behavior and collaborative ability – not just their experience.

    Many companies now offer project-based assignments and trial roles that let them evaluate performance before making a permanent hire.

    At the same time, employers are investing in internal reskilling and upskilling programs. Reskilling refers to training workers for entirely new roles, often in response to job changes or automation, while upskilling means helping employees deepen their current skills to stay effective and advance in their existing roles. Our report indicates that approximately 88% of large companies now offer structured upskilling and reskilling programs. For job seekers and workers alike, staying competitive means taking the initiative and demonstrating a commitment to learning and growth.

    Show up early, and show up well

    So what can students, or anyone entering or reentering the workforce, do to prepare?

    • Start early. Don’t wait until senior year. First- and second-year internships are growing in importance.

    • Sharpen your soft skills. Communication, time management, problem-solving and ethical behavior are top priorities for employers.

    • Understand where work is happening. Over 50% of entry-level jobs are fully in-person. Only 4% are fully remote. Show up ready to engage.

    • Use AI strategically. It’s a useful tool for research and practice, not a shortcut to connection or clarity.

    • Stay curious. Most large employers now offer reskilling or upskilling opportunities – and they expect employees to take initiative.

    One of the clearest takeaways from this year’s report is that hiring is no longer a one-time decision. It’s a performance process that often begins before an interview is even scheduled.

    Whether you’re still in school, transitioning in your career or returning to the workforce after a break, the same principle applies: Every opportunity is an audition. Treat it like one.

  • MIL-OSI Analysis: Observers of workplace mistreatment react as strongly as the victims − at times with a surprising amount of victim blaming

    Source: The Conversation – USA – By Jason Colquitt, Professor of Management, Mendoza College of Business, University of Notre Dame

    Workplace mistreatment harms observers, too. AP Photo/Ross D. Franklin

    Picture this: On your way out of the office, you notice a manager berating an employee. You assume the worker made some sort of mistake, but the manager’s behavior seems unprofessional. Later, as you’re preparing dinner, is the scene still weighing on you – or is it out of sight, out of mind?

    If you think you’d still be bothered, you’re not alone. It turns out that simply observing mistreatment at work can have a surprisingly strong impact on people, even for those not directly involved. That’s according to new research led by Edwyna Hill, co-authored by Rachel Burgess, Manuela Priesemuth, Jefferson McClain and me, published in the Journal of Applied Psychology.

    Using a method called meta-analysis – which takes results from many different studies and combines them to produce an overall set of findings – we reviewed the growing body of research on what management professors like me call “third-party perceptions of mistreatment.” In this context, “third parties” are people who observe mistreatment between a perpetrator and the victim, who are the first and second parties.

    We looked at 158 studies published in 105 journal articles involving thousands of participants. Those studies explored a number of different forms of workplace mistreatment ranging from incivility to abusive supervision and sexual harassment. Some of those studies took part in actual workplaces, while others examined mistreatment in tightly controlled laboratory settings.

    The results were striking: We found that observing a co-worker being mistreated on the job has significant effects on the observers’ emotions. In fact, we found that observers of mistreatment may be as affected by what happened as the people actually involved in the event.

    These reactions fall along a spectrum – some helpful, others less so. On the encouraging side, we found that observers tend to judge perpetrators and feel empathy for victims. These reactions discourage mistreatment by creating a climate that favors the victim. On the other hand, we found that observers may also enjoy seeing their co-workers suffer – an emotion called “schadenfreude” – or blame the victim. These sorts of reactions damage team dynamics and discourage people from reporting mistreatment.

    Why it matters

    These findings matter because mistreatment in the workplace is disturbingly common – and even more frequently observed than experienced. One recent study found that 34% of employees have experienced workplace mistreatment firsthand, but 44% have observed it happening to someone else. In other words, nearly half of workers have likely seen a scenario like the one described at the start of this article.

    Unfortunately, the human resources playbook on workplace mistreatment rarely takes third parties into account. Some investigation occurs, potentially resulting in some punishment for the perpetrator and some support for the victim. A more effective response to workplace mistreatment would recognize that the harm often extends beyond the victim – and that observers, too, may need support.

    What still isn’t known

    What’s needed now is a better understanding of the nuances involved in observing mistreatment. Why do some observers react with empathy, while others derive pleasure from the suffering of others? And why might observers feel empathy for the victim but still respond by judging or blaming them? Answering these questions is a crucial next step for researchers and leaders seeking to design more effective workplace policies.

  • MIL-OSI Analysis: The hidden bias in college admissions tests: How standardized exams can favor privilege over potential

    Source: The Conversation – USA – By Zarrina Talan Azizova, Associate Professor of Education, Health and Behavior, University of North Dakota

    At first glance, calls from members of Congress to restore academic merit in college admissions might sound like a neutral policy.

    In our view, these campaigns often cherry-pick evidence and mask a coordinated effort that targets access and diversity in American colleges.

    As scholars who study access to higher education, we have found that when these efforts are paired with pressure to reinstate standardized tests, they amount to a rollback of inclusive practices.

    A Department of Education letter sent to congressional offices from Feb. 14, 2025, stated that is “unlawful for an educational institution to eliminate standardized testing to achieve a desired racial balance or to increase racial diversity.” The letter also claimed that the most widely used admissions tests, the SAT and ACT, are objective measures of merit.

    In our recent peer-reviewed article, we analyzed more than 70 empirical studies about the SAT’s and ACT’s roles in college admissions. Our work found several flaws in how these exams function, especially for historically underserved students.

    Measuring college readiness

    Supporters of admissions tests contend that they are objective tools for measuring whether students are ready for college-level coursework.

    Several elite universities – including Yale, Dartmouth and the Massachusetts Institute of Technology – have reinstated SAT or ACT requirements, reversing test-optional policies that institutions expanded during the COVID-19 pandemic.

    These changes have reignited debates about how well these tests measure students’ academic preparedness and how colleges should weigh them in admissions decisions.

    During a May 21, 2025, hearing of the U.S. House Subcommittee on Higher Education and Workforce Development, some witnesses argued that using test scores allows colleges to admit students based on merit. Others maintained that test scores can function as barriers to higher education.

    Our research shows that while these tests are statistically reliable – that is, they produce consistent results for students across subjects and during multiple attempts under similar conditions – they are not as valid as some argue.

    High school grade-point averages are typically better predictors of students’ success in college than either test.

    In addition, the tests are not equitable or similarly predictive for all students, especially given gender, race and socioeconomic demographics.

    That is because they systematically favor those with more access to high-quality schooling, stable socioeconomic conditions and opportunities to engage with test prep coaches and courses. That test prep can cost thousands of dollars.

    In short, both tests tend to reflect privilege more than potential.

    For example, students from higher-income households routinely outperform their peers on the ACT and SAT.

    This isn’t surprising, considering wealthier families can afford test prep services, private tutoring and test retakes. These advantages translate into higher scores and open doors to selective colleges and scholarship opportunities.

    Meanwhile, students from low-income families often face challenges – such as less experienced instructors and less access to high-level science, math and advanced placement courses – that test scores do not factor in.

    Reflecting deep inequities

    In the U.S., high school GPA can be a better predictor than standardized tests of college success.

    In our published review, we found that these disparities aren’t incidental – they’re systemic.

    Our review revealed long-standing evidence of bias in test design and differences in average scores along lines of race, gender and language background.

    These outcomes don’t just reflect academic differences; they reflect inequities that shape how students prepare for and perform on these tests.

    We also found that high school GPA outperforms standardized tests in predicting college success. GPA captures years of classroom performance, effort and teacher feedback. It reflects how students navigate real-world challenges, not just how they perform on a single timed exam.

    For many students, particularly those from historically marginalized backgrounds, grades can offer a better indication of how prepared they are for college-level work.

    This issue matters because admissions decisions aren’t just technical evaluations – they are value statements. Choosing to center test scores in admissions rewards certain kinds of knowledge, experiences and preparation.

    The American Council on Education defines equity as opportunities for success. It means building educational environments that recognize diverse forms of potential and equip all learners to thrive.

    It’s worth noting that research on testing often focuses on elite institutions, where standardized test scores are more likely to be used as high-stakes screening tools. Our systematic review found that, even in elite schools, the tests’ ability to accurately predict college academic performance is often limited (moderate in statistical terms).

    But most college students attend state universities, public regional universities, minority-serving institutions, or colleges that accept most applicants. Our study found that at these institutions, standardized test scores are even less likely to predict how students will do.

    This may be because state universities and public regional universities are more likely to serve highly diverse student populations, including older, part-time and first-generation students and those who are balancing work and family responsibilities.

    Where does higher ed go from here?

    Prioritizing standardized tests in college admissions could close the doors of opportunity for some capable students.

    With the debate over the role of standardized tests in the admissions process, higher education stands at a crossroads: Will colleges yield to political pressure and narrow definitions of merit and ignore equity? Or will institutions reaffirm their mission by embracing broader, fairer tools for recognizing talent and supporting student success?

    The answer depends on what values are prioritized.

    Our research and that of others make it clear that standardized tests should not be the gatekeepers of opportunity.

    If universities define merit on test scores alone, they risk closing the doors of opportunity to capable students.

  • MIL-OSI Analysis: A radical proposal to abolish state government and strengthen American democracy

    Source: The Conversation – USA – By Stephen Legomsky, John S. Lehmann University Professor Emeritus, Washington University in St. Louis

    Abolish all the states? Zoonar/Getty Images Plus

    Get rid of states? Legal scholar Stephen Legomsky, who taught for 34 years at the Washington University in St. Louis School of Law, has just published a book, “Reimagining the American Union,” that proposes a radical idea: Abolish state government. The Conversation’s politics and democracy editor, Naomi Schalit – a former statehouse reporter herself – interviewed Legomsky about the provocative idea behind his book, in which he advocates moving most of the functions of state government down to the local level, closer to those represented and governed by it.

    You propose abolishing states. Why?

    The book is a thought experiment. The proposal I’m offering is long term. I realize we need states during the current political moment.

    I think the states are the root cause of many, if not most, of the current dangers faced by U.S. democracy. I also see the states as a significant source of fiscal waste. We don’t need three levels of government – national, state and local – all regulating us and all taxing us. Two would do just fine. And after careful, detailed analysis, I concluded that every benefit ever claimed for state government could be achieved at least as well, and in many cases better, by the local governments.

    I’m imagining the framers sitting in Independence Hall. And you go back in time and suggest to them not having states. I think most of them would drop dead at the thought, because it ultimately implies a much more powerful federal government. What would you say to them?

    After they stop laughing, I would emphasize that I’m not proposing a wholesale transfer of power from the states to an all-powerful, all-knowing central government. Yes, some of the functions currently performed by the states could better be performed at the national level, but I’m proposing that the lion’s share devolve down to the local governments, which are even closer to the people they represent than the state legislatures can ever be.

    Some of the most ardent Federalists, including Alexander Hamilton and James Wilson, referred to the states as “artificial beings” or “imaginary beings.” They accepted the states only because keeping them was politically essential to getting the required nine state ratifications, not because they thought states were a good idea.

    George Washington’s working copy of the Constitution from Aug. 6, 1787.
    National Archives, Records of the Continental and Confederation Congresses and the Constitutional Convention

    What functions would your plan hand over to the federal government?

    A prime example is licensing. I looked up all the different occupations that require state licenses. I was astonished: practically every health care profession, barbers, engineers, lawyers, architects, the list is endless.

    If you live near a state line, you can’t practice in both states unless you get two licenses. If you move to another state, you have to get another license. This seems silly. The human anatomy, human hair, engineering principles, don’t change as you cross from New York to New Jersey. Nor do we need 50 different state driver’s licenses; a single national license administered through local agencies would be more efficient.

    You say states are the root cause of the greatest threats to American democracy. What are those threats?

    The structural threats are those that are baked into the Constitution itself. The Electoral College is one. On five occasions, the Electoral College has awarded the presidency to the candidate whom the voters rejected nationwide. And there were many, many near misses where the popular vote loser almost became president, making many such future instances a statistical certainty.

    Perhaps even more important, every state, no matter how large or how small, gets the same number of U.S. senators. In fact, a majority of the U.S. population is represented by only about 18% of the Senate. The minority gets the other 82%.

    These counter-majoritarian defects in the elections of both presidents and senators have a ripple effect. They skew the composition, and thus the decisions, of the federal courts. Three of the current Supreme Court justices were appointed by President Donald Trump after he had lost the national popular vote; five of the current Supreme Court justices were confirmed by senators who collectively represented only a minority of the U.S. population.

    Here’s one especially jarring statistic: From 1969 until today, the Democratic presidential nominees won the national popular vote in a slight majority of the elections. Yet, during the presidential terms that resulted from those elections, Republican presidents have gotten to make 15 of the 20 Supreme Court appointments.

    The Constitution also gives the states broad powers to regulate and run national elections. State legislatures have used those powers to pass gerrymandering, voter suppression and other counter-majoritarian laws.

    If you devolve these functions and services to localities, wouldn’t you end up with a mirror of the current state-level structure? Wouldn’t this just send a lot of state personnel down to the local level?

    Yes, much of that structure would devolve. However, I see that as a good thing. Devolution is unavoidable in a country this size. Not everything can be done by the central government. The question for me is, do we need two levels of subordinate political subdivisions or one? One seems more efficient. And when problems are too big for one local government to handle on its own, it can partner with other local governments or with the national government, just as many local governments do today.

    Abolishing state government means no more meetings of the state legislature, like this one in the Maine House of Representatives on Jan. 4, 2023, at the State House in Augusta.
    AP Photo/Robert F. Bukaty

    If there were no states to gerrymander or pass voter-suppression laws, wouldn’t some national government agency just do it instead?

    Redistricting would be performed by a nonpartisan redistricting commission that I propose be made up of technicians, mainly demographers, statisticians and geographers, under broad, general principles enacted by Congress. That’s what almost every other democracy in the world does today.

    Why did you write this book?

    For a long time, I’ve been distressed about so many of the dangers to our democracy. So, one day, I found myself compiling what ended up becoming a fairly long mental list of all of my democracy-related grievances.

    A list of grievances like in the Declaration of Independence!

    That’s a nice analogy. And as I thought about that list, it suddenly struck me that the vast majority of these problems couldn’t occur without states. That got me thinking about whether we really need states in the first place.

    If it’s just a thought experiment, something that’s not going to happen, why would you think it’s worthwhile spending time writing this?

    And why would I be so vain as to think anybody would want to waste their time reading it?

    And your answer is, ‘Because I’m an academic!’

    It’s that, plus more. I do hope there’s some scholarly value in this. But I’m also writing for the long term. States are secure for now, but history teaches us that the more distant future is full of surprises.

  • MIL-OSI Analysis: The use of federal troops to quell Los Angles protests recalls militarized law enforcement during the Civil Rights Movement

    Source: The Conversation – USA – By Justin Randolph, Assistant Professor of U.S. History, Texas A&M University

    President Donald Trump activated 4,000 National Guard troops on June 10, 2025, to quell protests in Los Angeles over immigration raids – without the normal request from the state. He has also sent to Los Angeles hundreds of U.S. Marines, with the goal of protecting the unprecedented deportation operations by U.S. Immigration and Customs Enforcement.

    If this all feels exceptional, it should. Governors typically activate their own state troops, as Texas Gov. Greg Abbott said he would do on June 11 ahead of expected immigration protests.

    California quickly sued the president. A federal court has sided with the state, but an appeals court will weigh the Trump administration’s use of the U.S. code on armed services to activate the National Guard, which relies on protesters constituting either an “invasion” or “rebellion.”

    “What we’re witnessing is not law enforcement – it’s authoritarianism,”
    California Gov. Gavin Newsom said on June 10.

    Protesters report violent responses from Los Angeles police, too. Nonetheless, Newsom’s invocation of authoritarianism is apt.

    The last example of a president federalizing troops over the objection of a state government dates to Jim Crow segregation, a period marked by legal practices that routinely denied due process and citizenship rights to Black Americans in the South. In the 1960s, numerous Black freedom struggles took stands against this authoritarianism backed by militarized law enforcement.

    As a scholar of U.S. history, I’ve just completed a book on Jim Crow policing and the ways Black Americans fought back against racist law and order. I think the militarization of policing in Los Angeles opens important questions about democracy and state violence.

    Jim Crow dreams

    During the Civil Rights Movement, the federal government activated National Guard troops over Southern state objections when those states would neither enforce court orders nor protect protesters.

    In those cases, presidents protected people with the help of troops. In Trump’s case, he’s using troops to protect the government from protesters.

    The Trump administration’s vision of law enforcement aims for the type of militarized authority that state governments institutionalized under Jim Crow policing. If your political enemy is perceived more like an enemy combatant, the rules of legal procedure, especially due process, might not apply. Policing becomes war.

    When you see the words “Jim Crow,” your mind may jump to photos of racially segregated water fountains. But Jim Crow was far more than that. It was homegrown racial authoritarianism, or the repression of freedom of thought and action.

    Before troops enforced civil rights, Black Southerners saw the National Guard as an enemy rather than a friend.

    In the words of Ida B. Wells-Barnett after a white riot against Black residents in St. Louis, Missouri, in 1917, “The police were either indifferent or encouraged the barbarities. … The major part of the National Guard was indifferent or inactive. No organized effort was made to protect the Negroes or disperse the murdering groups.”

    Eisenhower sends in the troops

    The U.S. Supreme Court’s 1954 decision in Brown v. Board of Education changed things. It overturned the 1896 Plessy v. Ferguson decision that legalized racial segregation and ruled that segregated public school education was unconstitutional. This significantly altered the federal government’s responsibility in the South’s legal system of white supremacy.

    The first test came in Little Rock, Arkansas, in 1957. Though numerous school districts across the South quietly desegregated, Southern governors such as Arkansas’ Orville Faubus resisted the planned desegregation of Little Rock Central High School.

    Faubus deployed the Arkansas National Guard to stop Black children at the door. For nearly three weeks, Guardsmen blocked the small group of Black students – known as the “Little Rock Nine” – who were supposed to attend the school before President Dwight Eisenhower federalized the Arkansas National Guard and ordered them to stand down.

    Eisenhower deployed U.S. Army riot troops to Little Rock under the Insurrection Act. In the end, the Little Rock Nine began their studies at Central High despite the much-photographed spitting from the white mob that surrounded the school.

    State troops, state rights

    Next came the desegregation of interstate transportation.

    In spring 1961, the Congress of Racial Equality, a civil rights advocacy group, sent buses of integrated passengers through the Deep South. White terrorists attacked Freedom Riders, as these activists became known, three times in Alabama.

    But state authorities had learned from the Little Rock experience. Southern governors in Alabama and Mississippi deployed the National Guard themselves. This time they intended to only minimally protect Freedom Riders to block federal law enforcement. In Mississippi, police arrested and prison guards tortured Freedom Riders in the state penitentiary. Mob violence killed no one.

    The same was not true during the desegregation of public universities.

    When U.S. marshals arrived to enforce the court order enrolling James Meredith at the University of Mississippi in September 1962, a white riot erupted. State law enforcement withdrew from the scene. Two men died, and many more were injured.

    President John F. Kennedy federalized the Mississippi National Guard and sent them in to restore order. The next summer, he did the same in Tuscaloosa, Alabama, to preemptively halt a riot at the University of Alabama.

    The occasion became a publicity stunt for Alabama Gov. George C. Wallace. He temporarily blocked the entrance to Foster Auditorium, intent on stopping the court-ordered registration of three Black students.

    “I stand before you here today in place of thousands of other Alabamians whose presence would have confronted you,” Wallace said to federal authorities. A National Guard general said, “Sir, it is my sad duty to ask you to step aside under the orders of the President of the United States.”

    Wallace also triggered the last federal use – until now – of the National Guard. Alabama’s Selma-to-Montgomery march began as a memorial to Jimmie Lee Jackson, a young Black civil rights activist who was killed by police on Feb. 26, 1965. The march became primarily a symbol for the year’s Voting Rights Act.

    In an important change, President Lyndon B. Johnson federalized the National Guard to protect marchers. State troopers and sheriff’s deputies had terrorized marchers, including John Lewis, who was almost beaten to death on Bloody Sunday, March 7, 1965.

    Democracy is in the streets

    The history of the National Guard in the South is an important part of what’s unfolding in Los Angeles and across the nation.

    For most of the National Guard’s history in the South, political leaders used domestic military power to preserve the interests of racial authoritarians, not racial egalitarians. Little Rock, Tuscaloosa, Selma: Those moments when troops protected racial justice protesters at home stand out as some of America’s most hopeful moments.

    Recent statements by Trump administration officials help illustrate how it envisions using military power in domestic law enforcement. On June 8, 2025, Homeland Security Secretary Kristi Noem asked Defense Secretary Pete Hegseth “to arrest rioters” – a request beyond the original order to protect ICE agents.

    And on June 12, Noem said that “the military people that are working on this operation … are staying here to liberate the city from the socialist and burdensome leadership that this governor and that this mayor have placed on this country.”

    The National Guard and Marines are reportedly protecting immigration enforcement. But what might happen if they directly interact with protests?

    With diverse tactics, protesters are halting business as usual because they see a mass-deportation regime terrorizing and disappearing people in their communities. U.S. courts tend to agree with their analysis but seem powerless to enforce even basic due process rights for those detained by ICE.

    These activists show the messy work of American social change. Their work may look like “anarchy” to even some Democrats. It may be maligned as “invasion” and “rebellion” by the Trump administration.

    But the calls to constrain ICE follow an American tradition of fighting authoritarianism.

  • MIL-OSI Analysis: AI ‘reanimations’: Making facsimiles of the dead raises ethical quandaries

    Source: The Conversation – USA – By Nir Eisikovits, Professor of Philosophy and Director, Applied Ethics Center, UMass Boston

    This screenshot of an AI-generated video depicts Christopher Pelkey, who was killed in 2021. Screenshot: Stacey Wales/YouTube

    Christopher Pelkey was shot and killed in a road range incident in 2021. On May 8, 2025, at the sentencing hearing for his killer, an AI video reconstruction of Pelkey delivered a victim impact statement. The trial judge reported being deeply moved by this performance and issued the maximum sentence for manslaughter.

    As part of the ceremonies to mark Israel’s 77th year of independence on April 30, 2025, officials had planned to host a concert featuring four iconic Israeli singers. All four had died years earlier. The plan was to conjure them using AI-generated sound and video. The dead performers were supposed to sing alongside Yardena Arazi, a famous and still very much alive artist. In the end Arazi pulled out, citing the political atmosphere, and the event didn’t happen.

    In April, the BBC created a deep-fake version of the famous mystery writer Agatha Christie to teach a “maestro course on writing.” Fake Agatha would instruct aspiring murder mystery authors and “inspire” their “writing journey.”

    The use of artificial intelligence to “reanimate” the dead for a variety of purposes is quickly gaining traction. Over the past few years, we’ve been studying the moral implications of AI at the Center for Applied Ethics at the University of Massachusetts, Boston, and we find these AI reanimations to be morally problematic.

    Before we address the moral challenges the technology raises, it’s important to distinguish AI reanimations, or deepfakes, from so-called griefbots. Griefbots are chatbots trained on large swaths of data the dead leave behind – social media posts, texts, emails, videos. These chatbots mimic how the departed used to communicate and are meant to make life easier for surviving relations. The deepfakes we are discussing here have other aims; they are meant to promote legal, political and educational causes.

    Chris Pelkey was shot and killed in 2021. This AI ‘reanimation’ of him was presented in court as a victim impact statement.

    Moral quandaries

    The first moral quandary the technology raises has to do with consent: Would the deceased have agreed to do what their likeness is doing? Would the dead Israeli singers have wanted to sing at an Independence ceremony organized by the nation’s current government? Would Pelkey, the road-rage victim, be comfortable with the script his family wrote for his avatar to recite? What would Christie think about her AI double teaching that class?

    The answers to these questions can only be deduced circumstantially – from examining the kinds of things the dead did and the views they expressed when alive. And one could ask if the answers even matter. If those in charge of the estates agree to the reanimations, isn’t the question settled? After all, such trustees are the legal representatives of the departed.

    But putting aside the question of consent, a more fundamental question remains.

    What do these reanimations do to the legacy and reputation of the dead? Doesn’t their reputation depend, to some extent, on the scarcity of appearance, on the fact that the dead can’t show up anymore? Dying can have a salutary effect on the reputation of prominent people; it was good for John F. Kennedy, and it was good for Israeli Prime Minister Yitzhak Rabin.

    The fifth-century B.C. Athenian leader Pericles understood this well. In his famous Funeral Oration, delivered at the end of the first year of the Peloponnesian War, he asserts that a noble death can elevate one’s reputation and wash away their petty misdeeds. That is because the dead are beyond reach and their mystique grows postmortem. “Even extreme virtue will scarcely win you a reputation equal to” that of the dead, he insists.

    Do AI reanimations devalue the currency of the dead by forcing them to keep popping up? Do they cheapen and destabilize their reputation by having them comment on events that happened long after their demise?

    In addition, these AI representations can be a powerful tool to influence audiences for political or legal purposes. Bringing back a popular dead singer to legitimize a political event and reanimating a dead victim to offer testimony are acts intended to sway an audience’s judgment.

    It’s one thing to channel a Churchill or a Roosevelt during a political speech by quoting them or even trying to sound like them. It’s another thing to have “them” speak alongside you. The potential of harnessing nostalgia is supercharged by this technology. Imagine, for example, what the Soviets, who literally worshipped Lenin’s dead body, would have done with a deep fake of their old icon.

    Good intentions

    You could argue that because these reanimations are uniquely engaging, they can be used for virtuous purposes. Consider a reanimated Martin Luther King Jr., speaking to our currently polarized and divided nation, urging moderation and unity. Wouldn’t that be grand? Or what about a reanimated Mordechai Anielewicz, the commander of the Warsaw Ghetto uprising, speaking at the trial of a Holocaust denier like David Irving?

    But do we know what MLK would have thought about our current political divisions? Do we know what Anielewicz would have thought about restrictions on pernicious speech? Does bravely campaigning for civil rights mean we should call upon the digital ghost of King to comment on the impact of populism? Does fearlessly fighting the Nazis mean we should dredge up the AI shadow of an old hero to comment on free speech in the digital age?

    No one can know with certainty what Martin Luther King Jr. would say about today’s society.

    Even if the political projects these AI avatars served were consistent with the deceased’s views, the problem of manipulation – of using the psychological power of deepfakes to appeal to emotions – remains.

    But what about enlisting AI Agatha Christie to teach a writing class? Deep fakes may indeed have salutary uses in educational settings. The likeness of Christie could make students more enthusiastic about writing. Fake Aristotle could improve the chances that students engage with his austere Nicomachean Ethics. AI Einstein could help those who want to study physics get their heads around general relativity.

    But producing these fakes comes with a great deal of responsibility. After all, given how engaging they can be, it’s possible that the interactions with these representations will be all that students pay attention to, rather than serving as a gateway to exploring the subject further.

    Living on in the living

    In a poem written in memory of W.B. Yeats, W.H. Auden tells us that, after the poet’s death, Yeats “became his admirers.” His memory was now “scattered among a hundred cities,” and his work subject to endless interpretation: “the words of a dead man are modified in the guts of the living.”

    The dead live on in the many ways we reinterpret their words and works. Auden did that to Yeats, and we’re doing it to Auden right here. That’s how people stay in touch with those who are gone. In the end, we believe that using technological prowess to concretely bring them back disrespects them and, perhaps more importantly, is an act of disrespect to ourselves – to our capacity to abstract, think and imagine.
