Day THIRTY-SEVEN of the US-Israeli war on Iran... and this morning the conflict entered a new and dangerous register. President Trump issued a forty-eight-hour ultimatum demanding Iran open the Strait of Hormuz or face further military consequences. Iran's military command publicly rejected the demand, characterising it as, in their words, 'helpless and nervous.' Overnight, US CENTCOM confirmed it rescued BOTH crew members of an F-15 downed over Iran — one recovered near Yasuj in central Iran, the second in what President Trump called, quote, 'one of the most DARING search and rescue operations' ever conducted. Iran's Revolutionary Guards claimed they destroyed several US aircraft during those same rescue operations. Trump separately claimed Iranian leaders were killed in a massive strike on Tehran — a claim that could not be independently verified at broadcast time. Iran, meanwhile, pressed its own offensive across the Gulf: Iranian drones struck Kuwait's power and water infrastructure, a fire broke out at Bahrain's Gulf Petrochemical Industries facility following a drone attack, and fires were reported at Abu Dhabi's Borouge petrochemical plant. In Baghdad, THOUSANDS rallied against what protesters described as a 'senseless' war. The forty-eight-hour clock is now running. Watch whether Washington escalates toward Gulf energy infrastructure — or whether back-channel contact through Pakistan produces any movement before the deadline expires.

That campaign against Gulf energy infrastructure carries a direct cost felt in economies far from the theatre of war. Australia this morning sought fuel supply assurances from Singapore, South Korea, Malaysia, and Japan — a signal of how profoundly the closure of the Strait of Hormuz is straining Indo-Pacific energy security. Thailand's seven-billion-dollar fishing industry is now in acute distress as fuel costs driven by the Iran conflict make commercial fishing economically unviable. And Hong Kong's finance chief acknowledged that Middle East conflict is weighing on investor sentiment — even as the territory implements its first mainland-style five-year plan. Three Indonesian UN peacekeepers killed in southern Lebanon last week were laid to rest today, with President Prabowo condemning the attacks. The Houthis claimed a cluster missile strike on Israel's Ben Gurion Airport. The energy shock is no longer a regional phenomenon — it is restructuring government finances, trade routes, and security alignments from the Gulf to the Pacific.

That same contest between military momentum and supply-chain fragility is visible in Ukraine, where Russia launched NINETY-THREE Shahed-type kamikaze drones overnight. Ukrainian air defences downed seventy-six, but seventeen struck ten locations across multiple oblasts — Dnipropetrovsk, Sumy, Kharkiv, Chernihiv, Odesa, and Poltava among them. In Sumy region alone, twenty-nine people were wounded, including NINETEEN children. A separate Russian drone strike on a market killed several civilians. Russian shelling in Kharkiv left one dead and eleven injured over the past day, including one child. Ukraine struck back: drones damaged an oil pipeline near Russia's port of Primorsk in Leningrad Oblast and ignited a fire at a refinery, while Ukrainian partisans disabled railway infrastructure on the Bryansk-to-Sumy supply line. On the diplomatic track, Kyiv says US envoys Witkoff and Kushner may visit Ukraine in April — though with Washington's strategic attention consumed by Iran, the timeline and substance of any peace framework remain deeply uncertain. The sovereign debt burden of sustaining this war — across Ukraine AND Europe — is a pressure that accumulates silently beneath the daily casualty counts.

And a brief but consequential development in AI governance: Britain is actively courting Anthropic to expand operations in the UK, following reported tensions between the company and US defence interests — a move that illustrates how frontier AI development is becoming inseparable from geopolitical alignment. New York's RAISE Act, enacted earlier this year, now stands as the most significant state-level AI safety regulation in the United States — even as Washington has moved in the opposite direction, seeking to pre-empt state regulation at the federal level. The gap between those two trajectories is widening. As military AI accelerates across every active conflict zone, the question of who governs these systems — and on whose behalf — is no longer abstract.
