The White House Plan to Buy Diego Garcia

The strike in March, where two Iranian missiles targeted the remote base, shattered the illusion that geographic isolation provides security. While neither missile hit the facility, the event revealed that Iran possesses intermediate-range capabilities previously underestimated by Western intelligence. For the U.S. military, the atoll remains an indispensable asset, functioning as an unsinkable aircraft carrier capable of projecting power from East Africa to the Indo-Pacific.

Washington’s primary concern is not just Tehran, but the growing influence of Beijing in Mauritius. U.S. officials fear that Chinese investment could eventually grant Beijing leverage over the base's operations and intelligence infrastructure. By purchasing the islands, the U.S. hopes to eliminate the legal uncertainty created by the 2019 International Court of Justice ruling and the subsequent 2025 sovereignty deal between London and Port Louis.

This strategy, however, threatens to alienate the United Kingdom, which has spent years navigating the complex legal and diplomatic fallout of the colonial-era removal of the Chagossian population. For Britain, a U.S. purchase would undermine its own sovereignty agreements and strain the 'special relationship.' Meanwhile, Mauritius faces a difficult choice between its decades-long pursuit of decolonization and the prospect of a massive sovereign wealth payout. Whether the U.S. can successfully execute this plan depends on whether Mauritius is willing to sell and if Congress is prepared to fund a move that challenges international legal norms to secure a vital military outpost.
