Why the White House Wants to Purchase the Chagos Islands and Bypass the UK

President Donald Trump reversed the US position in January 2026, calling the deal an "act of great stupidity" and linking it to his own territorial ambitions for Greenland . US opposition effectively stalled the legislation needed to finalize the transfer, and by April 2026 the deal was in limbo with no path to ratification before the end of the parliamentary session .

How a Direct Purchase Would Bypass the UK

The reported US proposal would cut the UK out of the equation entirely by negotiating a direct purchase agreement with Mauritius . Because the UK has already agreed to cede sovereignty to Mauritius, a US-Mauritius deal would give the United States full control over the territory—including the Diego Garcia base—without needing to navigate the UK's stalled legislative process .

The plan is one of several options being drafted by the White House as an alternative to British Prime Minister Keir Starmer's stalled cession plan .

Why Diego Garcia Matters

Diego Garcia is arguably one of the most strategically valuable military outposts on the planet. The joint US-UK base on the atoll has been operating since the 1970s and serves as the backbone of American power projection across the Indian Ocean region .

• Geography. Located in the central Indian Ocean, it sits at the crossroads of the Middle East, East Africa, South Asia, and Southeast Asia .
• Airpower. It is one of only two critical US bomber bases in the Indo-Pacific, alongside Andersen Air Force Base in Guam . Long-range bombers such as the B-2 Spirit and B-1 Lancer can reach targets deep inside the Middle East from Diego Garcia without requiring aerial refueling .
• Naval logistics. The island hosts 16 separate US commands and is described by the Navy as the "last link in the long logistics chain" supporting operations in the Indian Ocean and North Arabian Sea .
• Political reliability. Unlike basing options in Bahrain or Qatar, Diego Garcia does not come with host-nation restrictions or domestic political pressures that could limit US operations .
• Iran contingency. The base has moved to the center of planning for any potential strike on Iran's nuclear facilities, putting platforms and munitions beyond Tehran's reach while saving scarce aerial refueling assets .

From Greenland to Chagos: A Pattern of Territorial Ambition

The Chagos purchase proposal fits a broader pattern in the Trump administration's approach to territorial expansion.

President Trump proposed buying Greenland from Denmark in 2019, an offer that was categorically refused . During his second term, that ambition escalated: the administration threatened tariffs and military force to annex the Danish autonomous territory, triggering an international diplomatic crisis . Trump eventually stepped back in January 2026, pledging not to use force or tariffs .

Just six months later, the White House was reportedly drafting a plan to buy the Chagos Islands. Reporters have framed this as a pivot after the Greenland push "ended in failure"—a smaller, more achievable territorial purchase pursued through financial transaction rather than coercion .

Key Differences

• Willingness to sell. Denmark flatly refused to sell Greenland. Mauritius may be open to a transaction, making the Chagos proposal more diplomatically viable.
• Existing footprint. The US already operates the Diego Garcia base under a UK lease. A purchase would convert an existing arrangement into full sovereignty rather than establishing a new presence from scratch.
• Scale and approach. The Greenland effort was larger in geographic scope and involved threats of military force. The Chagos approach is reported as a quieter, purchase-only proposal .

What Happens Next

The proposal has not been confirmed by official US sources, and the White House and UK Foreign Office did not immediately respond to requests for comment . Until an official offer is made—or the White House confirms the plan—the future of the Chagos Islands remains locked in one of the most geopolitically sensitive sovereignty disputes in the Indian Ocean.
