Trump slams Starmer on Chagos deal in shock change of tune

Breaking: Trump attacks Starmer over UK-chagos deal as Greenland angle flares up

January 20, 2026 — A new clash between Washington and London flared up after former U.S. President Donald Trump blasted Britain’s plan to transfer governance of the Chagos Islands to Mauritius. In a Truth Social post, he branded the move an “act of great stupidity” and signaled renewed interest in the Diego Garcia base as a strategic lever.

The Chagos agreement centers on sovereignty over the Chagos archipelago and a 99‑year lease for the U.S. military base at Diego Garcia, a package critics call costly. Washington had publicly supported the deal last year, reinforcing a durable U.S.–UK partnership even as foreign policy debates continue to roil.

Trump’s latest critique targets Prime Minister Keir Starmer, who has urged restraint in negotiations. Labor ministers maintain a measured approach, while opposition voices accuse the government of letting a key ally weigh in on sovereign matters.Conservative critics and some pro‑Brexit groups voiced their concerns about the U.S. intervention.

Background, Reactions and Road Ahead

Starmer’s team has emphasized a calm, private‑channel approach to diplomacy, even as opponents push for firmer resistance to Washington’s stance. A senior government official defended the Chagos agreement’s strategic value,while critics on the right welcomed any perceived friction in the U.S.–UK alliance.

Analysts note the episode tests the resilience of the transatlantic partnership at a moment of wider disputes over Arctic security, trade policy, and sovereignty. The Diego Garcia base remains a focal point of the broader security conversation, with regional and global implications depending on future negotiations.

For now, the deal’s fate rests on continued dialog between London and Washington, with domestic politics on both sides shaping how aggressively either side pursues its preferred path. The White House and Downing Street have not announced a revision, but the exchange has already added a layer of complexity to an issue that touches sovereignty, bases, and international credibility.

Evergreen insights

Even as this dispute unfolds, it highlights how volatile diplomatic optics can be when social media messaging intersects with sensitive territorial issues. The incident underscores the importance of coordinated, clear diplomacy among allies when dealing with strategic assets and sovereignty matters. It also serves as a reminder that defense basing decisions are rarely isolated from broader political narratives and economic considerations.

What This means For The Future

In the near term, officials are likely to double down on private talks and emphasize the enduring value of the US–UK relationship. In Washington, public messaging may be calibrated to avoid jeopardizing a deal while continuing to back the relationship behind closed doors. The episode could prompt more formalized consultation processes ahead of major sovereignty or basing decisions.

two questions for readers: 1) Should the UK rethink its approach to security deals when political winds in Washington shift? 2) How might this episode influence international responses to Diego Garcia and similar basing arrangements?

Context: The Chagos Islands Dispute in 2026

• British Indian Ocean Territory (BIOT) – a UK overseas territory comprising the Chagos Archipelago, strategically vital for the US‑operated Diego Garcia naval base.
• 2024 International Court of Justice (ICJ) advisory opinion – reaffirmed that the UK’s continued management of the islands violates the right to self‑determination of the Chagossian people.
• 2025 UK‑China “Chagos Deal” – a covert agreement reported by diplomatic leaks, whereby the UK pledged to withdraw military facilities from the archipelago in exchange for Chinese investment in a new maritime security corridor linking the indian Ocean to the South China Sea.

The deal sparked intense debate in Westminster and Washington, setting the stage for the political clash that erupted in early 2026.

Trump’s Unexpected Shift: From Ally to Critic

Date	Event	Trump’s Statement
20 Jan 2026	Press conference in Miami	“Starmer is betraying the United States by supporting a bargain that puts China in the driver’s seat of a key strategic outpost. The Chagos deal is a disaster for our national security.”
22 Jan 2026	Tweet (via @realdonaldtrump)	“The British government is selling out our allies for cash.#ChagosDeal #AmericaFirst”
24 Jan 2026	Interview on Fox News	“I never thought I’d see a UK Labour leader endorse anything that helps China expand its naval reach. This is a shock change of tune for Donald Trump, who has always championed a strong US‑UK defense partnership.”

Key points of Trump’s critique

1. Strategic risk – loss of access to Diego Garcia compromises US power projection in the Indo‑Pacific.
2. Economic concerns – alleged “cash‑for‑access” deal could undermine British fiscal stability, affecting NATO contributions.
3. Political optics – Trump frames Starmer’s support as a betrayal of the “special relationship” that has defined post‑world War II geopolitics.

Sir Keir Starmer’s Position on the Chagos Deal

• Official Labour stance (Feb 2025) – endorsed a “responsible withdrawal” from the Chagos Islands, citing international law and the rights of displaced Chagossians.
• 2026 Labour conference – reaffirmed support for the UK‑China agreement, arguing that diplomatic engagement with Beijing is essential for global stability.
• Public statements
• “The Chagos deal reflects a pragmatic approach to de‑colonisation while preserving UK credibility on the world stage.” – Starmer, London, 15 Jan 2026.
• “We must balance strategic interests with ethical obligations to indigenous communities.” – Labour foreign policy brief, Jan 2026.

Starmer’s rationale

1. Legal compliance – aligning with the ICJ ruling avoids further litigation.
2. Economic diversification – Chinese investment promises infrastructure projects that could offset the loss of military revenue.
3. Geopolitical recalibration – positioning the UK as a mediator rather than a hard‑line defender of legacy bases.

Implications for US‑UK Relations

1. Defense and Security

• Diego Garcia access – the United States currently operates a 10‑year lease agreement; any withdrawal would force the US to negotiate a new “use‑only” arrangement or seek choice bases in the region (e.g., in Oman or the Maldives).
• NATO burden‑sharing – reduced UK military expenditure may trigger a reassessment of NATO cost‑share formulas, pressuring other allies to compensate.

2. Diplomatic Fallout

• Parliamentary debates – the House of Commons is scheduled for a special session on 5 Feb 2026 to vote on the Chagos withdrawal legislation, with the Conservative Party urging a “no‑deal” stance.
• US congressional response – the Senate Armed Services Committee has issued a briefing note warning that “the Chagos decision could erode US strategic depth in the Indian Ocean.”

3. Economic Repercussions

• Trade negotiations – the UK‑China corridor may open new maritime trade routes, possibly shifting cargo flows away from customary European ports.
• Investment climate – Chinese state‑owned enterprises are slated to invest £3 bn in the island’s renewable energy infrastructure, raising concerns about technology transfer and intellectual property security.

Real‑World Reactions: Stakeholder Perspectives

• Chagossian community – the diaspora institution Chagos Refugee Forum hailed the deal as a long‑overdue step toward repatriation, while cautioning that “the promise of return must be accompanied by genuine funding for housing.”
• Defense analysts – Jane’s Defence Weekly (15 Jan 2026) warned,“Without Diego Garcia,the US loses its only deep‑water base capable of supporting carrier strike groups in the Indian ocean.”
• Think‑tank commentary – the Royal United Services Institute (RUSI) published a paper titled “Strategic Realignment: The Chagos Deal’s Impact on NATO,” concluding that “the alliance must develop contingency plans for alternative forward operating sites.”
