UK PM Starmer Declares Iran Conflict Not Britain's War, Announces Hormuz Summit

British Prime Minister Starmer publicly broke with the US by declaring "this is not our war" regarding Iran. He announced plans for a summit to reopen the Strait of Hormuz through diplomatic means rather than military action. Trump responded by criticizing the UK and questioning Royal Navy capability. France separately joined Japan in agreeing to step up coordination on the Hormuz crisis, signaling a European preference for multilateral approaches.

Analysis
Starmer's public break with Washington, hosting a 35-nation Hormuz summit without US involvement, represents the most significant UK-US foreign policy divergence since Iraq 2003. The UK is positioning itself as a diplomatic alternative to US military unilateralism, which could either complement or undermine American objectives depending on whether diplomatic and military tracks remain coordinated.
