E3 (UK, France, Germany) resolve to back 'proportionate military defensive measures' against Iran

·Europe

The E3 (UK, France, Germany) resolved to support proportionate military defensive measures against Iranian drones and ballistic missiles. UK PM Starmer allowed US use of British bases for 'defensive' strikes.

In a significant diplomatic development, the E3 grouping of the UK, France, and Germany resolved to back 'proportionate military defensive measures' against Iranian drones and ballistic missiles. This signals potential for direct European military involvement beyond the French Rafale engagements already underway. British PM Keir Starmer said the US could use British bases for 'defensive' strikes on Iran and disclosed that Ukrainian and other specialists would aid Gulf efforts to counter Iranian drone strikes — leveraging Ukraine's extensive experience with Iranian-made Shahed drones. Germany's Chancellor Merz had earlier met with Trump at the White House, raising 'the day after' Iran as a pressing concern. The E3 position represents the most significant European security commitment since the start of the conflict.

I raised with President Trump the urgent question of 'the day after' in Iran. Germany and Europe must have a voice in shaping what comes next. De-escalation pathways must remain open.

Russia's calculation: High oil prices fund war in Ukraine. Western military assets diverted from Europe. US credibility tested. Iran as potential client state in ruins. Moscow sees opportunity in every direction.

PHAROS NOTEUK 'defensive operations' framing carefully avoids language that would classify as offensive participation. Bases 'available' is passive consent for US strikes.
