President Donald Trump unloaded on the United Kingdom Tuesday morning via Truth Social, calling its Chagos Islands deal with Mauritius an "act of GREAT STUPIDITY." The post targeted PM Keir Starmer's government for agreeing last May to cede sovereignty while leasing back Diego Garcia—home to a crucial joint US-UK military base in the Indian Ocean. "Shockingly, our 'brilliant' NATO Ally, the United Kingdom, is currently planning to give away the Island of Diego Garcia... FOR NO REASON WHATSOEVER," Trump wrote.
