Would UK support for further US strikes on Iran risk escalating Middle East conflict?

US strikes targeted Iranian nuclear and military sites in early 2026 following attacks on shipping and escalation with Israel. The UK offered defensive assistance including missile defence and limited base access but refused offensive support, focusing instead on diplomacy, reopening the Strait of Hormuz and a de-escalation memorandum. At the July 2026 NATO summit in Ankara, President Trump expressed disappointment that the UK, France, Germany and Italy declined to back further US action.
