Britain’s attorney general, Richard Hermer, has expressed concerns about the legality of the UK participating in a bombing campaign against Iran, advising that the UK should only provide defensive support to allies. This advice may impact the level of UK support for potential US military action in Iran. The Prime Minister chaired an emergency Cobra meeting to discuss diplomatic efforts amidst escalating tensions between Israel and Iran. President Trump is deliberating launching strikes against Iran, contingent on the effectiveness of a bunker buster bomb in destroying Iran’s critical uranium enrichment facility at Fordow. Iran and Israel have engaged in hostilities, with Israel targeting Iran to thwart its nuclear ambitions, while Iran asserts its nuclear program is peaceful. Disabling Fordow is crucial in preventing Iran from obtaining nuclear weapons. Keir Starmer, considering international law, is tasked with decision-making in this crisis. The UK’s use of military bases, such as Diego Garcia and RAF Akrotiri, for potential airstrikes on Iran is under scrutiny. The UK’s recent lease agreement with Mauritius for Diego Garcia complicates matters, as approval from Starmer would be required. The US may seek RAF Akrotiri for air tanker refueling in a military operation. Amidst these deliberations, the priority remains finding a diplomatic resolution to prevent a destabilizing regional conflict. The shadow foreign secretary, Priti Patel, has cautioned against using legal advice as a shield in the face of national security imperatives.
