President Trump has backed down from his efforts to stop the United Kingdom from surrendering the key Chagos Islands in the Indian Ocean to Mauritius. Only weeks ago, Trump rightly opposed the United Kingdom’s planned surrender of the island of Diego Garcia, a move that would benefit the top threat to the American way of life: the Chinese Communist Party. Since then, Trump has announced that he had productive negotiations with the British government and the transfer to Mauritius will go forward, the British will lease Diego Garcia for the next century at least, and the United States reserves the right to use force to defend it.
There’s no doubt that smoothing relations with the United Kingdom is good as the United States and European Allies go through a turbulent time, but we should hope that President Trump privately continues to encourage the U.K. government to keep these islands.
The second Trump administration’s 2025 National Security Strategy and 2026 National Defense Strategy documents do not describe the threats China poses to the United States and the American way of life the way they did in the first Trump administration. Still, the cold war between the United States and China has intensified. The Trump administration, albeit muting its criticism of China, is not backing away from its claims to vital interests that span the globe, including a free and open Indo-Pacific and unobstructed sea lanes in the Middle East. Keeping the CCP from absorbing Diego Garcia is important for both of those vital interests; getting the United Kingdom to walk this back may have come just in time.
Diego Garcia is the largest island within the Chagos Archipelago, a chain of over 60 small coral islands that are British Indian Ocean Territory. And while there has been a highly contentious political fight and pressure campaign for the United Kingdom to relinquish control over these islands to Mauritius, the reality is that geography matters today just like it did in 1965 when the United Kingdom retained its claim to the islands before recognizing the independence of Mauritius. The islands were used as a U.S.-U.K. joint military base, and its military utility is as relevant now as it was then in countering the Soviet Union. The base became known as “Camp Justice” and supported U.S. bomber aircraft among other naval assets and intelligence operations.
The Trump administration may be underemphasizing the nature of the threats posed by China, though it does emphasize its vital interests in keeping sea lanes open, and especially vital shipping chokepoints. The 2025 National Security Strategy makes this explicit: “We want to halt and reverse the ongoing damage that foreign actors inflict on the American economy while keeping the Indo-Pacific free and open, preserving freedom of navigation in all crucial sea lanes, and maintaining secure and reliable supply chains and access to critical minerals.”
