Washington, Copenhagen and Nuuk have agreed a permanent security arrangement for Greenland, President Donald Trump announced on Friday. The deal, described by Trump as an "Infinite Life" agreement with no expiration date, gives the United States permanent control over security on the Arctic island and blocks any non-NATO country from setting up bases, deploying forces or making sensitive investments there without written US approval.
The announcement caps more than a year and a half of geopolitical drama. Since returning to the White House in January 2025, Trump repeatedly pushed for the US to simply acquire Greenland, at one point refusing to rule out force — a stance that badly strained relations with Denmark, a NATO ally, and was firmly rejected by Greenlanders themselves. The new arrangement instead keeps Danish sovereignty intact while locking in American access.
According to a senior State Department official, the US will retain permanent basing, access and overflight rights — and crucially, those rights would survive even if Greenland, whose 57,000 residents have long pushed for greater autonomy, eventually becomes independent from Denmark. Secretary of State Marco Rubio said the deal "permanently and completely" settles US security concerns, while Denmark's Prime Minister Mette Frederiksen stressed that it preserves the kingdom's sovereignty and Greenland's right to self-determination. Greenland's own premier, Jens-Frederik Nielsen, said the agreement respects the territory's interests.
The formal signing is expected next week on the sidelines of the UN General Assembly in New York. The US already runs Pituffik Space Base in northwest Greenland under a 1951 defense agreement updated in 2004, and reports suggest Washington may want up to three more facilities in the island's south — though neither side confirmed that on Friday.
So why does this matter to travellers? Greenland has been in the headlines for all the wrong reasons lately, and the uncertainty has cast a shadow over its image as a destination. A settled security arrangement removes the most destabilising scenario and signals a measure of stability for an island that's becoming easier to reach, with direct flights from North America and Europe feeding a slowly growing tourism scene built on icefjords, northern lights and Inuit culture. Nuuk and the south, where any new facilities might go, are the areas most likely to see infrastructure upgrades — often a side benefit of a larger military footprint. Whether the deal changes what's actually possible on the ground for visitors remains to be seen, but for anyone eyeing the world's largest island, the political fog has lifted somewhat. Watch the fine print as the terms emerge.
