The Briefing

Tehran issued evacuation warnings for Jebel Ali, Khalifa, and Fujairah ports — the first time since the war began that Iran has directly threatened a neighbor's civilian infrastructure rather than claiming to target only American military assets. The shift from targeting bases to naming the commercial arteries of global trade marks an escalation in kind, not just degree.

• Iran designated three major UAE ports as 'legitimate targets,' claiming the U.S. launched strikes on Kharg Island from Emirati territory — an allegation the UAE categorically denies.
• Gulf air defences have intercepted over 3,100 Iranian missiles and drones across six nations since February 28, with at least two dozen civilians killed.
• Brent crude has surged past $103 per barrel, a 40 percent increase since fighting began, with the Strait of Hormuz effectively closed to commercial shipping.
• The Gulf states' decades-long model of hosting American military assets while maintaining diplomatic distance from Washington's conflicts is being dismantled by the one country it was designed to manage.

Seven ballistic missile salvos struck Israel overnight, with roughly half of Iran's 300 missiles fired since the war began now carrying cluster warheads that scatter submunitions across a ten-kilometre radius. The tactical shift matters more than the declining salvo count — a single missile dispersing 70 bomblets over Tel Aviv rewrites the definition of 'successful intercept.'

• At least three people were wounded; 3,481 Israelis are now staying in hotels after their homes were declared uninhabitable.
• Iran's daily missile rate has fallen from roughly 90 on the first day to approximately five, after the IDF reported destroying 60% of Iran's launcher stockpile.
• Competing reports emerged over Israel's interceptor reserves, with Semafor reporting critical shortages and the IDF issuing flat denials.
• The shift to cluster munitions means the residual Iranian arsenal is performing differently than the full one did — a form of tactical adaptation that volume metrics do not capture.

IDF spokesman Brig. Gen. Effie Defrin told CNN the military has plans extending through Passover and three weeks beyond — the most explicit timeline Israel has offered. The statement sits uneasily alongside Trump's 'short-term excursion' framing and Energy Secretary Wright's repeated prediction that fighting will end 'in the next few weeks.'

• Over 15,000 targets have been struck across Iran, with more than 10,000 munitions deployed by the IDF alone in sixteen days.
• U.S. spending has reached $16.5 billion in twelve days; the IEA has released a record 411.9 million barrels from emergency reserves.
• The total death toll across twelve affected countries now stands at approximately 2,497, with more than 24,000 wounded.
• A campaign that has already exceeded the scale of any Western military operation since Iraq 2003 is being described by its political sponsors as a temporary disruption.

Tehran moved from rejecting ceasefire talks outright to publishing three formal preconditions — recognition of Iran's rights, war reparations, and guarantees against future aggression. The shift from refusal to conditional engagement is the substantive development, even though analysts describe all three demands as functionally unworkable.

• Foreign Minister Araghchi had rejected ceasefire talks as recently as March 5; the new conditions came twelve days into the campaign that killed Supreme Leader Khamenei.
• Trump demanded 'unconditional surrender,' defined as Iran being unable to fight any longer — a position as maximalist as Tehran's.
• New Supreme Leader Mojtaba Khamenei, an IRGC-affiliated hardliner, controls institutions that outrank the presidency on military matters.
• Both leaders are now constrained by the rhetoric they chose in the war's first week — the conditions are less a negotiating position than the architecture of a future climbdown.

Anti-government demonstrations have spread to at least six provinces, with protesters chanting 'Down with the dictatorship' rather than demanding electricity. The decoupling of political demands from the material grievance is a historically recognisable phase shift — and the regime's emergence of Raúl Castro's grandson as an unofficial interlocutor with Washington signals awareness of it.

• No petroleum shipments have reached Cuba in three months; the island has lost an estimated 90 percent of its fuel supply after Venezuela's government fell and U.S. sanctions blocked alternatives.
• Protesters stormed a Communist Party headquarters in Morón; video captured apparent gunfire and a young man collapsing.
• President Díaz-Canel confirmed talks with the Trump administration and released 51 prisoners, while at least 760 political prisoners remain jailed.
• Twenty-hour blackouts do not produce distributed frustration — they produce synchronised desperation across entire provinces, which is a different problem for a security apparatus that depends on isolating dissent geographically.

Pyongyang launched its largest single salvo of the year — ten nuclear-capable KN-25 missiles — during U.S.–South Korea exercises, at the precise moment the Pentagon is relocating THAAD interceptors from the Korean Peninsula to the Gulf. The timing tests whether the American security guarantee can survive being stretched across two active theatres.

• The missiles flew roughly 350 km from Sunan toward the East Sea; fifty new five-tube KN-25 launchers were formally transferred to the North Korean military in February.
• The Pentagon has been moving THAAD launcher vehicles and up to 48 interceptors from South Korea's Seongju base to the Middle East.
• South Korean President Lee acknowledged Seoul 'cannot fully impose our position' on American force deployments while insisting deterrence is unaffected.
• The same saturation arithmetic Iran has used to overwhelm missile defences in the Gulf is being rehearsed on the Peninsula, at the moment the interceptors designed to answer it are being shipped out.

After the Supreme Court struck down IEEPA tariffs, the administration reached for a 1974 trade provision never used by any president — designed for balance-of-payments crises under fixed exchange rates that ceased to exist in 1973. Twenty-four states argue the triggering conditions cannot be met, and the pattern reveals a search algorithm iterating through the U.S. Code rather than a policy.

• The states contend the 2024 balance-of-payments figure was approximately 0.2 percent of GDP, not the 'large and serious' deficit the statute requires.
• The federal government collected $264–287 billion in customs duties in 2025, a 192 percent increase from the prior year.
• The Court of International Trade has ordered refunds of an estimated $175 billion in illegally collected IEEPA duties to more than 330,000 importers.
• The tariffs expire in 131 days unless Congress extends them — and Section 301 investigations are already queued as the next instrument if this one falls.

Europe's largest-ever seed round values a twelve-person, no-product startup at $3.5 billion on the thesis that autoregressive language models are a developmental cul-de-sac. The investor list — Nvidia, Bezos, Schmidt — overlaps substantially with the backers of the LLM paradigm, making this hedge capital rather than contrarian conviction.

• AMI Labs will develop world models based on LeCun's Joint Embedding Predictive Architecture, which predicts high-level representations rather than next tokens.
• Five of six founders came from Meta-FAIR, the research lab LeCun built before Meta restructured it toward commercial deployment under Scale AI's Alexandr Wang.
• CEO Alexandre LeBrun predicted 'world models' would become the next fundraising buzzword within six months — an unusually honest description of the cycle that will dilute the term.
• The round is less a bet on AMI than a priced acknowledgement by the industry's largest players that whether token prediction leads to genuine machine understanding remains genuinely open.

Houston Methodist researchers found that TDP-43 — dysfunctional in over 95% of ALS and frontotemporal dementia cases — acts as a master regulator of DNA mismatch repair. The discovery mechanistically explains the decades-old epidemiological puzzle of why neurodegenerative patients rarely develop cancer, and vice versa.

• TDP-43 controls five key mismatch repair genes; deviation in either direction — depletion or overexpression — destabilises the genome through different pathways.
• In cancer databases, elevated TDP-43 correlated with increased mutation loads; in neuronal models, hyperactive repair machinery damaged the cells it was meant to protect.
• A metabolic product called fructose-2,6-bisphosphate partially restored a DNA repair pathway impaired by TDP-43 dysfunction in patient-derived neurons.
• The first molecular mechanism connecting two of medicine's largest unsolved disease categories was hiding inside a protein that 95% of ALS researchers were already studying — for a different reason.

Hungary and Slovakia are blocking a €90 billion EU loan and weapons deliveries to Ukraine until Russian crude flows resume through the Druzhba pipeline — which was damaged by a Russian drone strike in January. The two governments most dependent on Russian oil are blaming the country it was bombed in, not the country that bombed it.

• Budapest has blocked the EU loan, halted fuel exports to Ukraine, and vetoed new Russia sanctions; Slovakia declared an oil emergency and cut emergency electricity to Kyiv.
• Hungary's dependence on Russian crude has increased from 61 to 86 percent since 2021 — the inverse of the EU trend, which fell from 26 to approximately 3 percent.
• Brussels developed a contingency plan involving €30 billion in bilateral loans from Baltic and Northern European states, signalling it expects the veto to hold.
• The EU's unanimity mechanism, designed to protect member sovereignty, is functioning with some precision as a tool for two governments to protect their energy relationship with the country the rest of the bloc is sanctioning.
