President Donald Trump is reportedly considering a U.S. purchase of the Chagos Islands as part of an effort to secure long-term American control of the strategically vital Diego Garcia military base, according to a report published Sunday by the Telegraph, the latest twist in a years-long dispute involving Britain, Mauritius, and one of Washington’s most important overseas installations.

Citing U.S. officials familiar with the discussions, the Telegraph reported that Trump administration officials have explored whether the United States could acquire the archipelago as an alternative to a plan by British Prime Minister Keir Starmer’s to transfer sovereignty to Mauritius.
