President Donald Trump told America's allies to fend for themselves as the Strait of Hormuz continues to constrain the world's oil supply. Trump called on countries like the United Kingdom to either buy American oil or to "build up some delayed courage" and go into the strait themselves. Trump also said that he had already done all the dirty work, telling other countries they need to start relying on themselves rather than the United States. 'The upcoming days will be decisive.'"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," Trump said in the Truth Social post Tuesday. "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.""You'll have to start learning how to fight for yourself, the U.S.A. won't be there to help you anymore, just like you weren't there for us," Trump said. "Iran has been, essentially, decimated. The hard part is done. Go get your own oil!"
