Trump Criticizes UK's Chagos Islands Transfer Amid Greenland Pursuit

Trump slams UK's Chagos Islands move, linking it to Greenland acquisition.

U.S. President Donald Trump has criticized the United Kingdom's decision to transfer sovereignty of the Chagos Islands to Mauritius, despite prior U.S. support for the move. Trump described the decision as an act of "stupidity," linking it to his desire to acquire Greenland. The UK and Mauritius signed a deal in May 2025 to grant Mauritius sovereignty over the Chagos Islands, while the UK would lease back Diego Garcia, home to a vital U.S. military base, for 99 years. The U.S. government had previously welcomed the agreement. The UN and its top court have urged Britain to return the islands to Mauritius. The UK evicted thousands of Chagos islanders in the 1960s, who have since sought compensation in British courts.

Background

The Chagos Archipelago's history is deeply rooted in colonialism and strategic geopolitical interests. Uninhabited until the late 18th century, the islands were settled by enslaved Africans and laborers brought by the French. In 1814, the islands were ceded to Britain following the Napoleonic Wars and administered as a dependency of Mauritius.

The pivotal moment came in the 1960s, as Mauritius moved towards independence. The UK, seeking to retain control of Diego Garcia for military purposes, detached the Chagos Archipelago from Mauritius in 1965, creating the British Indian Ocean Territory (BIOT). This separation occurred despite objections from Mauritian leaders and laid the foundation for the subsequent displacement of the Chagossians.

Latest Developments

Recent developments concerning the Chagos Islands extend beyond the UK-Mauritius agreement. International pressure on the UK to relinquish control has intensified, with the UN General Assembly repeatedly calling for the islands' return to Mauritius. The International Court of Justice (ICJ) issued an advisory opinion in 2019, stating that the UK's administration of the Chagos Archipelago was unlawful and that it should be ended as rapidly as possible.

Chagossian advocacy groups continue to fight for the right of return and reparations. The UK government has faced increasing scrutiny over its handling of the situation, with calls for a formal apology and compensation for the displaced islanders. The long-term future of the U.S.

military base on Diego Garcia remains a key factor in the ongoing negotiations.
