The United States military’s most strategically vital Indian Ocean installation—launching point for every major Middle East operation since the Gulf War—now depends on a nation with free trade agreements with Beijing, currency swaps with the People’s Bank of China, and no contractual obligation to Washington.
When Britain signed away sovereignty of the Chagos Islands to Mauritius in May 2025, Secretary of State Marco Rubio called it a “monumental achievement.” Eight months later, President Trump called it “GREAT STUPIDITY.” Neither explained why Washington accepted an arrangement where its strategic linchpin operates at the pleasure of a third party it has no deal with.
The US leases Diego Garcia from Britain under an agreement expiring in 2036. Britain now leases from Mauritius under a 99-year treaty costing £101 million annually. Mauritius holds sovereignty. If Mauritius terminates Britain’s lease—for non-payment, political pressure, or Chinese leverage—Washington has no recourse. The “Footprint of Freedom” rests on a handshake America wasn’t party to.
The International Court of Justice opinion that supposedly compelled this surrender was advisory, not binding. The ICJ has no enforcement mechanism. When the same court ruled against the United States in 1986 over Nicaragua, Washington withdrew from compulsory jurisdiction and refused to comply. Britain could have done the same. Instead, the UK capitulated to a 13-1 opinion—the sole dissent from the American judge—and volunteered to create this vulnerability.
Mauritius signed a free trade agreement with China in 2021, maintains currency swap agreements with Beijing, and imports $993 million from China annually while exporting $26 million. Senator John Kennedy warned that “China is circling Mauritius.” The treaty includes no prohibition on Chinese presence beyond a 24-mile buffer around Diego Garcia. Mauritius can license facilities on surrounding islands. The precedent is Hong Kong, where China broke a 50-year pledge the moment it became inconvenient.
The payment structure compounds the risk. Miss a payment, Mauritius gains termination leverage. That’s not security; that’s a subscription service for an installation the US built and operated for half a century.
The Chagossians—approximately 2,000 forcibly removed between 1968 and 1973, now 10,000 descendants scattered across three countries—got no vote. When the House of Lords passed an amendment requiring a Chagossian referendum, the Starmer government responded that Chagossians have “no right to self-determination therefore no legal entitlement to referendum.” The UN Committee on the Elimination of Racial Discrimination urged suspension, warning the deal “will perpetuate longstanding violations.” Chagossians say they “want to remain British” and distrust Mauritius due to “historical marginalisation, neglect, racism and human rights abuses.”
The hypocrisy cuts deep. When Trump pushed to acquire Greenland, Starmer insisted the territory’s future must be decided by Greenlanders—who have a parliament, a prime minister, and an explicit legal pathway to independence referendum. Chagossians get a £40 million trust fund, roughly one percent of what Mauritius receives, and a permanent ban from Diego Garcia.
Mauritius’s claim rests on colonial paperwork. Britain administered Chagos from Mauritius between 1814 and 1965 as administrative convenience—no cultural or historical connection existed. The islands sit 1,400 miles from Port Louis but 450 miles from the Maldives. The ICJ treated Mauritius as the wronged party. It said nothing about handing the Chagossians from one distant government to another without consent.
Diego Garcia hosts B-2 stealth bombers—six deployed in March 2025, 30 percent of the operational fleet. Its lagoon anchors pre-positioned ships with supplies for an entire Marine brigade. Nuclear submarines make port calls. The US Navy calls it “an all but indispensable platform” for the Middle East, South Asia, and East Africa. The nearest US territory, Guam, sits 5,535 miles away. Losing Diego Garcia means losing power projection across an entire hemisphere.
Trump blessed this arrangement in February 2025, gave final approval in April, and watched Rubio celebrate it in May. By January 2026, after Britain backed Denmark on Greenland, he reversed course. The vulnerability existed the entire time. The administration chose not to see it until the politics shifted.
The US now operates its most important Indian Ocean base at the sufferance of a nation it has no agreement with, economically dependent on America’s chief strategic rival, with termination leverage built into every annual payment. The 99-year timeline assumes Mauritius will remain a reliable Western partner through nearly a century of Chinese economic pressure.
If this is what “securing the base for generations” looks like, someone should ask who’s securing whom.
