US retains right to military secure, reinforce American presence in Diego Garcia: Trump on UK's Chagos Islands deal

Former President Trump asserts the US right to defend its Diego Garcia military base, criticizing the UK's sovereignty deal with Mauritius over the Chagos Islands.

"I retain the right to Militarily secure and reinforce the American presence in Diego Garcia. - Donald Trump"

Washington DC, February 6

US President Donald Trump on Thursday said he has held "very productive discussions" with British Prime Minister Keir Starmer regarding the strategically located island of Diego Garcia, which hosts a major UK-US joint military base in the Indian Ocean.

Trump said that, though he understood the British Prime Minister had negotiated "the best he could make" under the circumstances, he would never allow the US presence at the military base to be "undermined" or "threatened".

In a post on Truth Social, Trump described Diego Garcia as being of "great importance" to US national security due to its central location in the Indian Ocean and its role in supporting American military operations.

"It is the site of a major U.S. Military Base, strategically situated in the middle of the Indian Ocean and therefore, of great importance to the National Security of the United States," Trump said.

Trump credited recent US military successes to the strength of American warfighters, modern military equipment and the strategic positioning of US bases worldwide, including Diego Garcia.

He referred to the lease arrangement of the UK-Mauritius Treaty, signed in 2025, which provides that Mauritius will exercise full sovereignty over the Chagos Archipelago, with the UK retaining rights on Diego Garcia for an initial 99-year period.

Trump said he understood that the British Prime Minister Starmer had negotiated "the best he could make" under the circumstances.

However, Trump warned that the United States would take decisive action if its military presence on the island were ever threatened.

"If the lease deal, sometime in the future, ever falls apart, or anyone threatens or endangers U.S. operations and forces at our Base, I retain the right to Militarily secure and reinforce the American presence in Diego Garcia, " he said.

Trump also rejected what he described as "fake claims or environmental nonsense" being used to undermine the US presence at the base.

"Let it be known that I will never allow our presence on a Base as important as this to ever be undermined or threatened," he added.

Earlier, US President Donald Trump criticised the United Kingdom over its plans to give away the Diego Garcia island and called it an act of "great stupidity". He said that London's action is one of several reasons Greenland must be "acquired".He made the remarks on January 20 in a Truth Social post.

The US President said, "Shockingly, our "brilliant" NATO Ally, the United Kingdom, is currently planning to give away the Island of Diego Garcia, the site of a vital U.S. Military Base, to Mauritius, and to do so FOR NO REASON WHATSOEVER. There is no doubt that China and Russia have noticed this act of total weakness. These are International Powers who only recognize STRENGTH, which is why the United States of America, under my leadership, is now, after only one year, respected like never before. The UK giving away extremely important land is an act of GREAT STUPIDITY, and is another in a very long line of National Security reasons why Greenland has to be acquired. Denmark and its European Allies have to DO THE RIGHT THING. Thank you for your attention to this matter."

Trump's remarks came shortly after the third reading of the Diego Garcia Military Base and British Indian Ocean Territory Bill on January 13 in the UK Parliament.

The UK-Mauritius Treaty, signed in 2025, provides that Mauritius will exercise full sovereignty over the Chagos Archipelago, with the UK retaining rights on Diego Garcia for an initial 99-year period.

Over the 99-year period, the UK will pay Mauritius around £3.4 billion at 2025/26 prices. The UK Government says this resolves the long-standing BIOT sovereignty dispute and secures the military base for continued operations in the long term, according to the UK House of Commons Library.

Trump's sharp tone stood in stark contrast to the Biden administration's stance on the treaty, which hailed the historic Chagos archipelago agreement between the United Kingdom and Mauritius and highlighted how diplomacy can overcome long-standing challenges to reach peaceful, mutually beneficial outcomes.

Former President Biden said the agreement affirms Mauritian sovereignty over the Chagos Archipelago while granting the United Kingdom authority to exercise Mauritius's sovereign rights over Diego Garcia.

From an international law perspective, Mauritius finally getting sovereignty is the right outcome. The Chagossians deserve justice. But Trump's rhetoric completely undermines the diplomatic process. Calling it "great stupidity" is disrespectful to all parties involved in the negotiation.

Honestly, as an Indian, I'm more worried about China's reaction to this than the US-UK deal. If they see Western powers squabbling, they might try to increase their own presence in the region. Our navy needs to be vigilant. The Indian Ocean is our backyard.

Trump casually connecting this to acquiring Greenland shows how transactional his foreign policy is. Everything is a real estate deal. It's worrying when global security is treated this way. The Biden approach of supporting diplomacy was far better for regional stability.

£3.4 billion for 99 years? That's a lot of money for Mauritius. Economically, it could be a big boost for them. But at what cost? Sovereignty is not just about money. Trump's threat to "militarily secure" the base if the deal falls apart is pure bullying.

The base has been there for decades. The practical reality is that the US isn't going anywhere from Diego Garcia, treaty or no treaty. Starmer probably got the best deal he could. Trump's bluster is just for his domestic audience. Still, India must ensure its strategic interests are protected in any new arrangement.
