Former U.K. Prime Minister Tony Blair criticized current Prime Minister Keir Starmer for what he described as damaging the United Kingdom’s relationship with the United States during the recent conflict involving Iran.

Speaking at an event hosted by Jewish News, Blair said it was a mistake for the British government to initially refuse a request from President Donald Trump to allow U.S. forces to use British bases during the early stages of the military operation.

Although the British government later reversed course and permitted the use of U.K. facilities for what it described as defensive purposes, Blair argued that the initial refusal created unnecessary tension between the two allies.

Blair said the alliance with the United States remains central to Britain’s national security and that the country should demonstrate clear support for its partner during moments of crisis.

He added that alliances are tested during difficult circumstances rather than easy ones, and that the American request was relatively limited in scope.

Blair also dismissed the idea that domestic political pressure should have influenced the decision. He argued that leaders sometimes must take firm positions even when they face opposition within their own parties.

The dispute comes amid heightened tensions following the launch of Operation Epic Fury, the joint military campaign involving the United States and Israel targeting Iranian military infrastructure.

President Trump previously expressed frustration with Starmer over the initial decision, saying he was disappointed by the refusal. He also compared the situation unfavorably to the historic wartime partnership between the United States and Britain under leaders such as Winston Churchill.

Blair, who strongly supported the United States during the Iraq War while working with President George W. Bush, said the transatlantic alliance remains essential for Britain’s security and global influence.
