UK and France convene 40-nation Hormuz summit, pledge defensive maritime mission without US

Macron and Starmer hosted roughly 30-40 nations at the Elysee for the Strait of Hormuz Maritime Freedom of Navigation Initiative, with the UK and France committing to lead a multinational mine-clearance and reassurance force once Iranian and US guarantees against firing or blockade are secured. Berlin and Rome attended in person; Washington was excluded by design. Starmer called the strait's reopening a global responsibility and said more than a dozen nations have pledged assets, with a follow-on military planning summit set for Northwood next week.

Analysis
The deliberate exclusion of Washington makes this a hedge against US unilateralism rather than a complement to it; US planners may instead have steered the initiative offstage to preserve allied minesweeping capacity while giving Trump deniability on a surge Washington itself cannot currently provide. Deployment is unlikely before the Lebanon ceasefire window closes in mid-April and remains contingent on Iranian commitments against firing on flagged vessels; with reporting converging, there is moderate confidence the mission stands in some form within 60 days. The load-bearing question is whether Berlin and Rome pledge combat-capable assets or symbolic flagship presence; that answer distinguishes a functional mine-clearance and reassurance force from a diplomatic placeholder.
