Summary

Trump Reverses Chagos Support

U.S. President Donald Trump has reversed support for the United Kingdom's Chagos Islands deal, calling it "an act of great stupidity."
The reversal complicates Prime Minister Keir Starmer's effort to win Trump's favor amid tensions over Greenland.
The fate of the deal depends on U.S. adherence to the 1966 treaty asserting British sovereignty, a concern echoed by Kemi Badenoch.

History

Historical Context

The Chagos Islands, forcibly depopulated between 1967 and 1973 to establish a US military base on Diego Garcia, were separated from Mauritius by the UK in 1965. In 2019, the International Court of Justice ruled that the UK's administration was unlawful. Following negotiations, the UK agreed in October 2024 to transfer sovereignty to Mauritius while retaining control over Diego Garcia for 99 years, impacting regional geopolitics.
