Trump Criticises UK-Mauritius Chagos Islands Deal Amid Strategic Security Debate

US President Donald Trump sharply criticised the UK’s plan to transfer sovereignty of the Chagos Archipelago, including the Diego Garcia military base, to Mauritius, calling it an "act of great stupidity" and "total weakness." This marks a reversal from his earlier support, when the US government endorsed the deal as securing strategic interests. The UK and Mauritius signed the agreement in 2025, with Britain retaining operational control of Diego Garcia under a long-term lease. Mauritius and the UK defend the deal as lawful and vital for regional security, while Trump links his criticism to his broader national security agenda, including his interest in acquiring Greenland.
