UK Prime Minister Keir Starmer has firmly refused pressure from Donald Trump to join the escalating Iran conflict, stating the UK will not be “dragged into this war.” Tensions have intensified after Trump criticised Britain’s absence in US-led efforts and suggested trade agreements could be reconsidered. Starmer reiterated that joining the war is not in the UK’s national interest, despite growing external pressure. The dispute highlights increasing strain in US-UK relations amid the wider US–Israel–Iran conflict and rising global uncertainty.
