President Trump delivered his fiercest rebuke yet to Prime Minister Sir Keir Starmer’s decision: ceding the Chagos Archipelago beneath the joint UK-US military hub is nothing short of a national security crime.

Starmer’s government has agreed to hand over British Indian Ocean Territory—including Diego Garcia, the fulcrum of our power projection in Asia-Pacific—to Mauritius, only to lease it back for a century at multibillion-dollar expense. This reckless deal trades strategic advantage for political theater.

President Trump took to Truth Social in the pre-dawn hours, calling the giveaway “an act of great stupidity” and warning that America’s adversaries are watching. He made clear that no NATO ally should abandon a base that safeguards Western interests from the Persian Gulf to the South China Sea.

China’s influence over Mauritius makes the surrender even more perilous. Under this arrangement, Beijing’s proxies could infiltrate critical communications networks and surveillance systems on Diego Garcia. There can be no softer defense when the Chinese Navy patrols our shipping lanes.

Nigel Farage’s Reform UK has rightly slammed Starmer’s appeasement. “Thank goodness Trump has vetoed the surrender of the Chagos Islands,” Farage declared, after revealing how White House insiders were misled into rubber-stamping the UK’s cover-your-eyes capitulation.

Downing Street clings to the fiction that a UN advisory opinion left them no choice. This is patently false. The United Kingdom has always possessed full sovereign rights over the territory. By bowing to a powerless tribunal, Starmer broadcasts weakness to Beijing and Moscow alike.

Britain’s Attorney General and top advisors—vetted by human-rights zealots—disregarded strategic reality. Now our joint base is imperiled by parliamentary maneuvers and opaque backroom lobbying. The Commons vote scheduled for today risks cementing one of the greatest self-inflicted wounds in modern defense policy.

This fiasco stems from the Biden administration’s last-minute pressure campaign. Reports confirm that Washington quietly urged London to clinch the deal before Trump’s return. Yet publicly, the White House warned of Chinese espionage risks—proof that even the Democrats knew the giveaway was unconscionable.

President Trump has made clear: the United States will not tolerate any dilution of our forward posture on Diego Garcia. Greenland taught us that vital real estate cannot be pawned for political optics. The Chagos Islands stand as red lines.

Republicans in Congress must demand full transparency on any leaseback agreement. Allied leaders in Canberra, Tokyo, New Delhi, and Seoul must echo this resolve. Britain must reverse course or face the strategic fallout of a blunder that will echo for generations.
