Diego Garcia Dispute: Trump Criticizes UK Plan, Links to Greenland Acquisition
WASHINGTON – On Tuesday, January 20, 2026, former U.S. President Donald Trump publicly criticized the United Kingdom’s plan to transfer sovereignty of the Chagos Archipelago, including the island of Diego Garcia, to Mauritius. Trump characterized the move as ”a massive act of stupidity” and suggested it further justifies the United States acquiring Greenland. He voiced these concerns via his social media platform,Truth Social.
Background of the Dispute
Diego Garcia is a strategically vital island in the Indian Ocean,currently hosting a joint U.S.-UK military base. The island’s history is complex, marked by the forced displacement of its original inhabitants, the Chagossians, in the 1960s and 70s to make way for the base (Wikipedia). For decades, the UK maintained control of the Chagos Archipelago, while the U.S. utilized Diego Garcia for military operations, notably during the Cold war and the “War on Terror.”
UK-Mauritius Agreement
In october 2024, the United Kingdom announced an agreement to transfer sovereignty over the Chagos Archipelago to Mauritius (Reuters). This agreement was formally signed in May 2025.The transfer acknowledges Mauritius’s long-standing claim to the islands and aims to address the grievances of the chagossian people, who have been seeking the right to return to their homeland. However,the future of the U.S. military base remains a key point of contention.
Trump’s Reaction and Concerns
Trump strongly opposed the UK’s decision, stating that relinquishing control of Diego Garcia is a “total act of weakness” that Russia and China will exploit. He argued that the move undermines U.S. national security interests and provides further justification for the U.S. to acquire Greenland, a territory he previously expressed interest in purchasing (BBC News
