Breaking AI & Tech News Analyzed

The Shift in Defense EthicsFormer GCHQ head David Omand has called for the integration of moral guidelines into future AI-powered weapon systems, arguing that autonomous drones are the only way to manage the speed of modern warfare. Omand, who previously chaired a 2014 commission on armed drones expressing doubts about AI's ability to distinguish civilians, now believes technology can "formalize moral authority" to ensure compliance with international humanitarian law.From Skepticism to "Adaptive Moral Control"Omand's intervention marks a significant pivot in the debate over autonomous weapons. He proposes an "adaptive moral control layer" where humans set the parameters of a mission—such as the expected proximity of civilians—before deployment. The AI then operates within these constraints, making split-second targeting decisions that reflect "sound moral reasoning." This approach aims to move away from the "in the loop" model, where a human authorizes every action, to an "on the loop" model where humans supervise the system's parameters.The $54bn AI Arms RaceThe push for ethical AI in warfare is fueled by massive investment and the reality of modern combat. The US is aggressively pursuing this technology, allocating $54bn for autonomous systems in its 2027 budget. This spending is driven by the need to shorten the "kill chain" in conflicts like the Iran war, where AI tools from companies like Palantir and Anthropic are already being deployed to process data faster than human operators can react.Redefining Human Oversight in CombatThe debate is fundamentally changing how military leaders view human involvement. Omand argues that relying on humans to make every decision in the "heat of combat" is operationally impossible and likely to lead to worse collateral damage. Instead, he envisions a future where machines execute attacks under strict human-defined ethical boundaries. However, critics like Chris Cole of Drone Wars UK argue that AI is merely a data processor incapable of the cognitive judgment required to distinguish combatants from civilians or judge proportionality.The Future of Automated WarfareThe consensus among defense analysts is that the shift to "on the loop" systems is inevitable. As warfare accelerates, the ability to program ethical constraints into autonomous systems may become a standard requirement for military capability. The challenge moving forward will be ensuring that these "moral codes" are robust enough to prevent civilian casualties while maintaining the speed advantage that AI provides.

The Lead: Europe's Defense AwakeningIn a small workshop in England's East Midlands, engineers at the British startup Skycutter are designing weapons for Ukraine. The swarms of cheap, deadly and often autonomous drones deployed in that war have already changed combat completely, forcing European militaries to scramble to catch up in a drive to spend billions on weaponry. This push comes with added pressure from Donald Trump's wavering on the Nato alliance and the US president's insistence that members increase defence budgets.The New Arms Race: Survivable vs. Attritable WeaponsMilitaries do not believe they can totally dispense with people or heavier machinery such as tanks, artillery and ships. But a big chunk of the planned spending will go on drones of various sizes, whether for the air, land, sea or below the waves. Gen Sir Roly Walker, the UK's chief of the general staff, last year said he wanted the forces' equipment to be 20% "survivable" (because they have people inside), 40% "attritable" (you aren't too worried if they're destroyed), and 40% "consumable" (single use).The growing feeling across Europe is that "we should be able to stand up on our own two feet," according to one person at a fast-growing weapons startup. "Sovereignty is about control. If you buy things off the shelf from elsewhere you are always ceding some control." That applies to parts and materials as well. The UK is consulting on how much needs to come from Britain for a product to be sovereign. Manufacturers cannot necessarily rely on parts and materials from various countries who could become adversaries – notably China.The Financial Surge: €800 Billion and CountingThe EU has responded by promising to spend €800bn on defence over four years. The UK has also pledged to put aside more, with Keir Starmer likely to come under pressure to show progress after Labour's heavy losses in recent elections. A crop of well-funded startups are gaining momentum and expanding production, making big promises – many still unproven – that they can do a better job than traditional manufacturers and Silicon Valley rivals.European defence tech unicorns include Helsing, a German company backed by the Spotify founder Daniel Ek, and the German drone makers Quantum Systems and Stark Defence. Stark and Helsing recently won orders from Germany's military for attack drones, while all but Quantum are investing in UK factories. The British missile maker Cambridge Aerospace – controversially chaired by the former defence secretary Grant Shapps – is reportedly also close to joining the billion-dollar ranks.Geopolitical Shifts: Redefining European Defence PostureThe unsettling combination of Trump and war on the doorstep has sharpened long-running criticism that the continent has relied too much on US weapons makers. "A lot of supply chain diversification dreams have evaporated," says Kusti Salm, a former Estonian defence mandarin turned chief executive of the anti-drone missile startup Frankenburg. "I think it's natural if Europe wants to sustain its prosperity and freedom."Ricardo Mendes, chief executive of the drone maker Tekever, says the advent of unmanned aerial vehicles has prompted "a radical transformation in how defence technology is built", with companies betting on future demand for kit rather than locking in long-term contracts before starting. Tekever, which Mendes co-founded in Portugal in 2001, reached a billion-dollar "unicorn" valuation last year, and has 1,200 people, including new factories in the UK's drone cluster in Swindon, Wiltshire, and another in Cahors, south-west France.The Future Outlook: European Defence Innovation EcosystemUS rival unicorns include the drone maker Shield AI, the autonomous boat company Saronic Technologies, and the anti-drone weapons company Epirus. But two companies with names taken from JRR Tolkien's Lord of the Rings lead the American pack: the software company Palantir and the autonomous weapons maker Anduril. Both are making significant inroads into Europe, particularly the UK, but that expansion is coming under scrutiny as European politicians balk at their stridently pro-Trump backers.Palantir was backed by the billionaire Trump donor Peter Thiel. Thiel, a vocal critic of liberal democracies, has also backed Stark, which has raised concerns in Germany, though Stark says Thiel has no direct operational or strategic influence. Palantir's chief executive, Alex Karp, has repeatedly extolled American dominance, while Anduril is run by 33-year-old Palmer Luckey, who has personally hosted a Trump fundraiser and has cultivated close ties with the administration.As Europe pours billions into defense technology and sovereignty, the landscape of global defense manufacturing is being reshaped. The coming years will determine whether European startups can deliver on their promises and establish a sustainable defense ecosystem independent of traditional suppliers and geopolitical dependencies.

The US-Iran Conflict Escalation Two months since the US and Israel launched a joint surprise attack on Iran, negotiations appear deadlocked, as competing blockades of the Strait of Hormuz continue to disrupt global energy supplies, and the future of Iran's nuclear programme remains unresolved. The Frozen Conflict Scenario All military options remain on the table, despite a ceasefire in force since April 8 having paused the conflict. Qatar's Ministry of Foreign Affairs on Tuesday cautioned against the possibility of a 'frozen conflict', where the critical waterway is used as a pressure card amid the possibility of violent flare-ups. The Cost of a 'Frozen' War The war between the US and Iran can already be described as 'frozen', but this no-war-no-deal scenario comes at too high a cost for both parties, Mehran Kamrava, an expert on Iran at Georgetown University in Qatar, told Al Jazeera. The American foreign policy think tank Quincy Institute estimated that Washington's costs incurred over the first month of the war were between $20bn and $25bn. A large-scale ground operation in Iran similar to that of Iraq in 2003 would require at least 500,000 personnel and some $55bn a month, or more than $650bn a year. Prolonged versus Protracted Conflict In Trump's initial projection, the war in Iran was intended to last 'four to five weeks'. Two months into the conflict, Chandler Williams, researcher at the Peace Research Institute Oslo (PRIO), says the prolonged conflict has lasted longer than forecast. The Impact of a Protracted Conflict Washington is betting on sustained economic and diplomatic pressure backed by Trump's constant threat to renew strikes to see if it can 'finish what air strikes alone cannot achieve', Williams said. For its part, Iran is aware of the US's military superiority and has opted for leveraging the Strait of Hormuz until the US decides that a negotiated settlement is preferable. 'Mowing the Grass' in Iran On Tuesday, the US Department of Defense requested $53.6bn for autonomous drones for the 2027 fiscal year, a roughly 24,000 percent increase from last year. If the tactics of the conflict shift towards drone warfare and towards a low-intensity conflict, this has lower costs for the attacker but a higher impact for the recipient as we've seen in the conflict between Ukraine and Russia, Michael Kerr, a historian and political scientist at King's College London, told Al Jazeera.
