Trump Revives Greenland Bid, Citing Diego Garcia Precedent

On the first anniversary of his inauguration as President of the United States, Donald Trump reiterated America’s interest in taking control of Greenland, invoking the recent agreement over Diego Garcia as a strategic precedent.

Trump pointed to the October 2024 decision by the United Kingdom to cede sovereignty of the Chagos Islands to Mauritius, while retaining long-term military access to Diego Garcia, as an example of how strategic interests can be preserved even amid changes in sovereignty.

The Chagos–Diego Garcia Agreement

In October 2024, the UK government announced what it termed a “historic political agreement” with Mauritius. Under the deal:

• Mauritius gains sovereignty over the Chagos Islands.
• The UK retains an initial 99-year lease over Diego Garcia, with an option to extend it.
• Britain will pay Mauritius for the lease.

The Diego Garcia military base will continue to be jointly operated by the United Kingdom and the United States.

Strategic Importance of Diego Garcia

The Chagos archipelago, consisting of 58 islands, lies around 500 km south of the Maldives in the Indian Ocean. Diego Garcia, the largest island, hosts one of the most significant US military bases outside the American mainland.

For Washington, the base is crucial due to:

• Its proximity to the Middle East, enabling rapid military deployment.
• Its role in monitoring the Indian Ocean and the Malacca Strait, a key chokepoint for global trade and a vital route for China’s energy and commerce.

Diego Garcia became fully operational as a military base in 1986.

Colonial Legacy and Displacement

The islands were uninhabited until the late 18th century, when the French brought enslaved labourers from Africa and India to work on coconut plantations.

• In 1814, France ceded the islands to Britain.
• In 1965, the UK created the British Indian Ocean Territory (BIOT), including Chagos.
• Although Chagos was administratively linked to Mauritius, it remained under British control when Mauritius gained independence in 1968.

To make way for the military base, Chagossian residents were displaced and resettled in Mauritius and Seychelles, with some later relocated to the UK in 2002.

Mauritius’ Long-Standing Claim

Mauritius has consistently argued that the UK’s control over Chagos was illegal and has raised the issue in international forums, including the United Nations. The 2024 agreement represents a major diplomatic victory for Port Louis, while allowing London and Washington to maintain their strategic footprint.
