Donald Trump erupted at the United Kingdom Tuesday morning over its refusal to join the United States in its war against Iran, issuing the European nation a notice that the United States would no longer be offering it “help.”

“All of those countries that can’t get jet fuel because of the Strait of Hormuz, like the United Kingdom, which refused to get involved in the decapitation of Iran, I have a suggestion for you: Number 1, buy from the U.S., we have plenty, and Number 2, build up some delayed courage, go to the Strait, and just TAKE IT,” Trump wrote on his social media platform Truth Social.
