Trump Slams UK’s Chagos Handover as “Act of Great Stupidity,” Cites Greenland Ambitions

January 20, 2026 — In a move that has sent shockwaves through the halls of Westminster and the Pentagon, President Donald Trump has launched a blistering attack on the United Kingdom’s decision to cede sovereignty of the Chagos Islands to Mauritius.

Taking to Truth Social on Tuesday morning, the U.S. President labeled the deal an “act of GREAT STUPIDITY,” marking a dramatic U-turn from his administration’s previous support for the agreement. Even more strikingly, Trump linked the “weakness” of the British government to his own intensifying campaign to acquire Greenland from Denmark.

The “Great Stupidity” of the Chagos Deal

The controversy centers on the Chagos Archipelago, a remote chain of islands in the Indian Ocean. While the UK has agreed to transfer sovereignty to Mauritius, the crown jewel of the territory—the Diego Garcia military base—is slated to remain under UK and US control via a 99-year lease costing London approximately £101 million per year.

President Trump, however, appears to have run out of patience with the arrangement. In his post, he wrote:

“Shockingly, our ‘brilliant’ NATO Ally, the United Kingdom, is currently planning to give away the Island of Diego Garcia, the site of a vital U.S. Military Base, to Mauritius, and to do so FOR NO REASON WHATSOEVER. There is no doubt that China and Russia have noticed this act of total weakness.”

Trump’s comments represent a significant headache for Prime Minister Sir Keir Starmer, who has spent months defending the deal as a “legal necessity” to resolve decades of international litigation. The UK government argues that without this treaty, the base’s operations would be vulnerable to international court rulings that could have paralyzed military activity.

The Greenland Connection

Perhaps the most unexpected twist in Trump’s critique was his pivot to the Arctic. The President argued that Britain’s willingness to “give away” land proves why the United States must secure its own strategic interests by any means necessary—specifically by acquiring Greenland.

“The UK giving away extremely important land… is another in a very long line of National Security reasons why Greenland has to be acquired,” Trump stated. “Denmark and its European Allies have to DO THE RIGHT THING.”

This comes as European leaders remain locked in a tense standoff with Washington over Trump’s threat to impose 10% to 25% tariffs on European goods unless a deal is reached for the sale of the semi-autonomous Danish territory.

Political Reaction: “Trump has Vetoed the Surrender”

In the UK, the President’s words were immediately weaponized by political rivals. Nigel Farage, leader of Reform UK and a long-time ally of Trump, took to X (formerly Twitter) to declare victory:

“Thank goodness Trump has vetoed the surrender of the Chagos islands,” Farage wrote, suggesting that the deal is now effectively dead in the water despite the UK’s legislative progress.

Conservative leader Kemi Badenoch mirrored this sentiment, calling the deal “complete self-sabotage” and arguing that the Prime Minister’s plan weakens NATO in the face of global adversaries.

National Security vs. International Law

The Diego Garcia base is often referred to as an “unsinkable aircraft carrier.” It has been a launchpad for major operations in the Middle East and South Asia and currently hosts nuclear-capable B-2 bomber

While the Starmer government insists the 99-year lease provides “ironclad” security, Trump’s intervention suggests he fears a “sovereignty slip” could allow Chinese influence to creep into the archipelago via Mauritius

As of Tuesday afternoon, Downing Street has maintained its position, with spokespeople stating that the UK “will never compromise on national security” and that the deal ensures the base remains operational for generations. However, with Trump now openly mocking his “brilliant” ally, the “Special Relationship” faces its most volatile test of the year.
