British Prime Minister Keir Starmer has stated that the UK does not support joining air operations against Iran, despite joining defensive operations in the region. Starmer stated that his government does not believe in regime change from the skies. He also rejected a request from the U.S. to use British bases to attack Iranian missile launchers. This decision prompted President Trump to publicly oppose a deal between the UK and Mauritius to surrender the sovereignty of British overseas territories. The UK's involvement in the Iran war is influenced by its decision to join the Iraq war during the Bush administration.
