February 19, 2026 — In a dramatic intervention into British politics, US President Donald Trump has called on UK Prime Minister Keir Starmer to abandon a controversial agreement concerning the sovereignty of Diego Garcia, a strategically crucial military base in the Indian Ocean. The demand follows an incident where four men landed on the territory, asserting their right to settle there.
Trump’s comments, posted on Truth Social, highlight the significance of the base for potential military actions, particularly against Iran. “Our relationship with the United Kingdom is a strong and powerful one, and it has been for many years, but Prime Minister Starmer is losing control of this important island by claims of entities never known of before,” Trump stated.
Strategic Importance of Diego Garcia
The Diego Garcia base is vital for US military operations, including potential strikes on Iran. Trump emphasized, “Should Iran decide not to make a Deal, it may be necessary for the United States to use Diego Garcia, and the Airfield located in Fairford [in England], in order to eradicate a potential attack by a highly unstable and dangerous Regime.”
Diego Garcia, one of the world’s most secretive military facilities, serves as a launch point for B-52 bombers and other aircraft destined for the Middle East. The base has hosted joint operations with Australian forces, reinforcing its strategic significance.
Contentious Sovereignty Deal
The controversy centers on a British agreement to pay £30 billion ($57 billion) to Mauritius over 99 years, acknowledging its sovereignty over the islands while leasing them back for continued military use. The recent landing by four men on Peros Banhos atoll, near Diego Garcia, has intensified the debate.
The UK government has condemned the landing as “illegal,” as the men claim ancestral rights to the islands. Their leader, Misley Mandarin, has refused to leave, stating, “They can make a threat however they want, I am not moving.”
Historical Context and Chagossian Rights
The Chagos Archipelago, including Diego Garcia, has a complex history. In the 1960s, the UK forcibly removed the Chagossians to establish the military base. Despite practical challenges, some descendants, supported by political figures like Nigel Farage, are campaigning for the right to return.
“Keir Starmer is now trying to evict the Chagossians who have resettled on their homeland,” Farage tweeted. “The Chagossian people deserve their right to self-determination.”
Political Ramifications and Forward Outlook
The dispute over Diego Garcia could have far-reaching political implications. Reform UK leader Nigel Farage is leveraging the issue to challenge Starmer, potentially influencing the next UK election in 2029.
The UK Foreign Office has labeled the landing as an “illegal, unsafe stunt,” asserting that it will not aid the Chagossian community. However, the government is working with Mauritius to facilitate visits to the islands, aiming to address historical grievances.
As tensions escalate, the future of Diego Garcia remains uncertain. The base’s strategic importance to the US and its allies underscores the complexity of the sovereignty debate. With Trump’s intervention, the issue has gained international attention, setting the stage for further diplomatic negotiations.
