President Donald Trump has criticised two major US allies for not providing enough support in the Iran conflict, accusing Spain of being "unfriendly" and the UK of not participating in the joint U.S.-Israeli strikes that killed Iranian Supreme Leader Ali Khamenei. He also criticized Britain's decision to cede the Chagos Islands, home to the crucial U.K.-U.S. military base, to the Republic of Mauritius. Spain has taken a stronger stance than the UK, denying the US. The president also expressed dissatisfaction with the UK's Prime Minister, Keir Starmer, over his refusal to participate in the strikes and criticized Spain's refusal to commit to NATO's new spending goal of 5% of gross domestic product on defense by 2035.
