U.S. President Donald Trump criticized U.K. Prime Minister Keir Starmer¡¯s plans to return sovereignty of Diego Garcia ¡ª an island that houses a crucial military base ¡ª to Mauritius, reversing his previous support for the proposal in a further deterioration of transatlantic relations.

Trump cited the decision to justify his ambitions for the U.S. to acquire Greenland, in a post on Truth Social early Tuesday morning.

¡°Shockingly, our ¡®brilliant¡¯ NATO Ally, the United Kingdom, is currently planning to give away the Island of Diego Garcia, the site of a vital U.S. Military Base, to Mauritius, and to do so FOR NO REASON WHATSOEVER,¡± Trump said. ¡°There is no doubt that China and Russia have noticed this act of total weakness.¡±
