G7 Foreign Ministers Split with Washington Over Iran War; Agree to Conditional Hormuz Security Mission

G7 foreign ministers meeting in France agreed to protect the Strait of Hormuz but made the security mission conditional on cessation of hostilities, rejecting US pressure for immediate action. Over 30 countries signed a statement expressing readiness to contribute to a post-war escort mission in a strictly defensive posture. Nearly all G7 nations have declined to participate in the US-Israeli military operation against Iran. The European Commission warned a prolonged conflict could trigger stagflation, reducing growth by 0.4 percentage points. Brent crude reached $110/bbl and European gas hovered around 54 EUR/MWh.

Analysis
The conditional nature of the Hormuz security agreement, active only after hostilities end, effectively gives Iran veto power over when the strait reopens to commercial traffic. No G7 nation will escort tankers through an active combat zone. The 30-nation statement is diplomatic cover, not an operational commitment.
