Donald Trump has said his military action against Iran is "saving" Britain from a nuclear attack, while renewing criticism of the UK for not fully backing the campaign. In a GB News interview, he also implied he might not support Britain if Argentina invaded the Falkland Islands, appearing to link this to the UK's reluctant stance on the Iran conflict, amid an ongoing row over the islands' sovereignty.

Trump argued that an Iran armed with nuclear weapons would pose a greater threat to Europe than to the US, given its missile capability. He referenced the UK's initial refusal, under then-prime minister Sir Keir Starmer, to join US-Israeli strikes on Iran, though Starmer later backed "defensive" action while declining to send the navy to reopen the Strait of Hormuz, prompting Trump to brand him "no Churchill". Trump also repeated warnings that the UK faces "disaster" without stricter immigration controls and energy policy changes, criticising London and its mayor, Sadiq Khan, whose office dismissed the comments and pointed to falling crime rates in the capital.
