U.S. President Donald Trump's Position on Diego Garcia

On February 18, 2026, U.S. President Donald Trump issued a warning to Britain regarding the strategic Indian Ocean base at Diego Garcia. He emphasized its importance for potential U.S. military actions against Iran.

Background

• The British Prime Minister, Keir Starmer, agreed to return the Chagos Islands to Mauritius, with plans for Britain to lease the Diego Garcia base for 100 years.
• Britain retained control over the Chagos Islands post-Mauritius independence in the 1960s, evicting thousands, who have since sought legal compensation.

Trump's Stance

• Trump criticized the proposed lease, suggesting it undermines British control.
• He warned that giving up control of Diego Garcia would harm the UK, labeling the claims of former island residents as "fictitious."
• Concerns were raised about potential instability, emphasizing the base's role in countering threats, specifically from Iran.

Response and Diplomatic Implications

• The British Foreign Office described the deal as essential for the security of the UK and its allies.
• The U.S. Department of State supported the UK-Mauritius agreement on the Chagos archipelago.

Geopolitical Context

• Trump considered military action against Iran, citing recent domestic crackdowns by Iranian authorities.
• The United States, along with Israel, had previously engaged in airstrikes on Iranian nuclear facilities.
• Trump emphasized the need to use strategic bases, like Diego Garcia and Fairford, for potential operations against Iran.

Clarifications and Internal Government Dynamics

• White House Press Secretary Karoline Leavitt confirmed Trump's social media statements as administration policy.
• Trump's previous acceptance of the UK-Mauritius deal, after discussions with PM Starmer, now appears to be reversed.
