Trump’s U-turn and the Future of the Chagos Islands

Editorial

The Indian Ocean is a key area for global power plays, but the Chagos Islands have caused more diplomatic trouble than almost anywhere else. For decades, the fight over these islands has been a leftover problem from the colonial era — viewed as illegal by international courts and shameful by human rights groups due to the forced removal of the Chagossians. However, a long-delayed plan to fix the crisis got a surprise boost yesterday: an endorsement from Donald Trump.

The US President’s signal of approval for the UK-Mauritius deal yesterday marks a striking reversal. Only weeks ago, Donald Trump had branded the agreement an “act of great stupidity,” linking it to his idiosyncratic pursuit of Greenland and fuelling fears in Whitehall that the “special relationship” might buckle under the weight of his “America First” scepticism. Now, following direct talks with Prime Minister Sir Keir Starmer, the rhetoric has shifted from “total weakness” to the “best deal he could make.” This change does more than just calm things down in Downing Street. It highlights the cold, hard realism (pragmatism) that is now driving the future of the Chagos Islands.

A Deal Born of Necessity

The agreement, finalized in May 2025 and currently moving through the UK Parliament, is a complex piece of geopolitical engineering. It provides for the transfer of sovereignty over the entire archipelago to Mauritius, finally addressing the 2019 International Court of Justice (ICJ) ruling that the UK’s continued administration was illegal. In exchange, the UK secures a 99-year lease for the joint UK-US military base on Diego Garcia — the largest and most strategically vital island in the chain.

For Sir Keir Starmer, the deal was never about idealistic decolonisation alone. It was a race against legal obsolescence. Had the UK continued to ignore international rulings, it faced the prospect of “provisional measures” from international courts that could have challenged the base’s operations. In short, to save the base, the UK had to surrender the islands.

The Trumpian Calculus

Trump’s initial outburst in January 2026, where he labelled the move a “surrender,” resonated with critics in the Conservative and Reform UK parties. Shadow Foreign Secretary Dame Priti Patel and others have long argued that Mauritius’s increasing economic ties with China make it a “Trojan horse” for Beijing’s influence in the Indian Ocean. Trump’s scepticism seemed to validate this “national security” critique.

However, the President’s recent “productive” dialogue with Keir Starmer suggests a shift toward a more transactional realism. Trump’s support comes with strings attached. By saying he will use the military to protect the base if the deal fails, he is making a one-sided promise to put U.S. interests first. This essentially ignores the details of Mauritius’s power over the islands and shows that, for Trump, American military control matters more than who officially owns the land.

This is the “Trumpian Pivot”: accepting the diplomatic framework of the deal while asserting a “might is right” fallback. It satisfies the immediate need for stability at Diego Garcia — a base essential for operations in the Middle East and the Indo-Pacific — while keeping a heavy hand on the scales of sovereignty.

The Cost of Sovereignty

For Mauritius, the deal represents the culmination of a half-century struggle for national dignity. By securing sovereignty over the Chagos, Mauritius completes its decolonisation process, an achievement Prime Minister Navin Ramgoolam has hailed as a historic victory.

Yet, the victory comes with significant caveats. The 99-year lease effectively ensures that the most important part of the territory remains a restricted military zone, beyond the reach of Mauritian civilian law for a century. Furthermore, the financial terms are substantial. The UK is set to pay an average of £101 million per year (in 2025/26 prices) for the lease, alongside capitalising a trust fund for the benefit of the displaced Chagossian people.

Critics in Mauritius and the displaced Chagos people argue that the new “ownership” is meaningless because even though Mauritius officially owns the islands, the people who were kicked out are still banned from their main home on Diego Garcia and are only allowed to move back to the smaller outer islands. Furthermore, politicians in the UK, like Kemi Badenoch, have labelled the deal a “surrender tax,” arguing that it is a poor decision for the UK to pay billions of pounds to rent land that it previously controlled for free.

Still in Exile

While the treaty includes provisions for a trust fund and the right to resettle the outer islands, many islanders feel the deal is a “betrayal.” For them, sovereignty is hollow if it does not include the right to return to Diego Garcia — the home they were promised would be theirs once it was “no longer needed for defence purposes.” The 99-year lease suggests that “defence purposes” are now defined in several decades, not years.

The Chagos deal is a classic exercise in the “art of the possible.” It removes a significant legal and diplomatic thorn from the UK’s side, provides the US with a century of relative certainty for its most important Indian Ocean asset, and grants Mauritius the title deeds to its stolen land.

Trump’s backing — grudging and conditional as it may be — removes the final major obstacle to ratification. It signals that even the most “disruptive” forces in global politics recognize that in an era of rising competition with China and Russia, a secure base is better than a legally contested one.

However, pragmatism should not be mistaken for a moral victory. The deal is a patchwork compromise that leaves Chagossians largely marginalized and Mauritian sovereignty subject to the military priorities of two global powers. It reflects the reality that global politics is often driven by strategic necessity rather than fairness or justice — the final decision was made because it was expedient, not because it was right.
