Brief du soir, mercredi 9 septembre

US Central Command disabled five Iranian-linked tankers after Iranian missile fire targeted a US Navy warship, while Tehran said it captured an American underwater drone and launched missiles at US-linked positions in Jordan. Jordan reported intercepting 18 of 20 missiles aimed at Al-Azraq airbase, and Iran warned tanker crews in Kuwait and Bahrain to leave port as it widened its threats to Gulf shipping. Brent briefly crossed $100 a barrel, and vessel traffic through Hormuz thinned as traders priced in the risk that a regional fight could become a global energy bill.

Washington framed the strikes as retaliation against ships it says help finance the Islamic Revolutionary Guard Corps, and US Secretary of State Marco Rubio described the approach in blunt commercial arithmetic.

Tehran cast its missile fire as retaliation for attacks on Iranian oil vessels, and Iranian Chief of Staff Ali Abdollahi promised further strikes if the tanker campaign continues.

The military contest now runs through insurance desks, fuel pumps and central-bank models, not just naval charts. Oil shocks rarely stay where the missiles land.

Jacob Coxon resigned from Anthropic and accused leading labs of racing toward systems they cannot control, turning an internal fear into a public spectacle after his thread drew almost 76 million views. He worked on pretraining at OpenAI and Anthropic, and warned that autonomous systems could move beyond human control by the end of 2027 under aggressive development paths.

OpenAI, meanwhile, published a 166-page paper and a Lean formalization claiming a solution to the Navier-Stokes Millennium problem. The company said an unreleased model used roughly 10,000 autonomous agents over 88 hours, producing more than 130 billion tokens and 3 million internal messages, but mathematicians immediately questioned attribution after parallel work by Tristan Buckmaster and Levent Alpöge surfaced. Francien Dechesne captured the unease over machine-generated mathematics.

Security officials added a geopolitical layer by accusing six Chinese AI companies of industrial-scale distillation from American frontier models, naming DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI. The advisory alleged billions of extracted tokens, fraudulent accounts and proxy routes, just as Washington and Beijing prepared AI-security talks.

The industry has produced miracles, alarms and lawsuits at once ; that is less a sign of maturity than of speed outrunning governance.

Donald Trump praised Alternative for Germany after the party won 43.8% in Saxony-Anhalt, where its state branch is classified by regional intelligence authorities as proven right-wing extremist. He framed the result as a revolt against immigration policy and revived his campaign grammar for German politics.

Berlin rejected the intervention. Metin Hakverdi, the federal government's transatlantic coordinator, said Germans would decide their own migration policy and elections without White House advice, while Chancellor Friedrich Merz used a Bundestag budget debate to confront Alice Weidel over the AfD's programme. The AfD more than doubled its 2021 result in Saxony-Anhalt, while the CDU fell to 17.2%, leaving traditional parties scrambling to block the far right from power in Magdeburg.

Merz sharpened the argument by attacking the AfD's remigration policy, saying mass removal plans would damage hospitals, care homes, restaurants and skilled trades as well as constitutional norms.

The Saxony-Anhalt result has become a transatlantic argument about who gets to bless Europe's insurgent right. Germany's firewall now faces pressure from voters on one side and applause from Washington on the other.

A technical failure at National Air Traffic Services cancelled more than 2,000 flights across Britain and Europe over two days, hitting Heathrow hardest and spreading delays to Gatwick, Manchester, Birmingham, Edinburgh, Jersey and continental hubs. Cirium counted 1,746 cancellations on Tuesday, equal to about 30% of scheduled UK flights, and 327 more by midday on Wednesday. NATS said it fixed the core fault by Tuesday evening, but airlines still had aircraft and crews in the wrong places the next day.

Transport Secretary Heidi Alexander summoned NATS chief executive Martin Rolfe and gave the company one week to explain the breakdown. She also instructed the Civil Aviation Authority to conduct an independent review, a signal that ministers no longer want to treat air-traffic failures as bad luck wrapped in technical language. Ryanair said about 150,000 of its passengers were affected after more than 200 cancellations, while British Airways cancelled or diverted 100 flights on Tuesday and at least 190 on Wednesday.

The breakdown marks the third NATS technical problem in three years, after a 2023 failure affected more than 700,000 travellers and cost airlines £100m. Carriers must now absorb rebooking, hotels, meal vouchers and lost capacity, while passengers learn again that resilience is something airports advertise best when they do not need it. A national air-traffic monopoly can turn a software fault into a border-wide tax on time.

Spain published 40 declassified intelligence documents to defend its handling of the mass Ceuta border crossing, while the European Union approved €114.7m in emergency aid for the enclave. The money will fund thermal cameras, extra police and civil-guard deployments, return procedures and more accommodation for unaccompanied minors. Madrid says about 5,000 migrants remain in Ceuta, while local authorities put the figure at at least 10,000, a gap that captures both the accounting problem and the political one.

The crisis began after more than 70,000 people entered Ceuta from Morocco over 48 hours at the end of July, by land and by swimming around sea barriers. Many returned quickly, but the city still reports overwhelmed services, outdoor encampments and pressure on schools, health care and policing. Ceuta President Juan Jesús Vivas pressed Brussels for help and described the enclave in language no finance ministry likes to hear.

Medical groups warned that respiratory infections were spreading among people sleeping outside, and local officials have already committed more than €6.1m to temporary shelters and supplies for minors. Spanish security forces have recorded thousands of images and videos from the Tarajal crossing, but software limits and inter-agency delays have slowed identification work. Europe often speaks about border control in abstractions ; in Ceuta it now has a crowded city, a legal backlog and children needing beds.
