US, Denmark and Greenland sign defence pact allowing Washington to build two new military bases while affirming Danish sovereignty.

In a groundbreaking meeting at the UN General Assembly, the United States, Denmark and Greenland reached a defence agreement that lets the US construct new bases in Narsarsuaq and Mestersvig. The pact reaffirms Denmark’s sovereignty and Greenland’s right to self‑determination, while explicitly barring non‑NATO forces from the archipelago. Trump’s earlier threats to acquire Greenland have been superseded by a diplomatic victory that strengthens NATO and US strategic presence in the Arctic.

In a historic ceremony at the United Nations General Assembly in New York, United States President Donald Trump, Danish Prime Minister Mette Frederiksen and Greenlandic Premier Jens‑Frederik Nielsen concluded a defence pact that permits Washington to construct military installations in two separate Greenlandic locations.

The agreement revises a 1951 accord and authorises US forces to set up Defence Areas in Narsarsuaq in the south‑east and Mestersvig in the east, while reaffirming Denmark’s sovereignty and Greenland’s autonomy. A key feature of the treaty is a clause that bars any non‑NATO country from establishing permanent military forces on the island.

Greenland, home to 56,000 residents, celebrated the deal as a victory for local economic and security interests. Trump’s earlier campaign claims to “take” the territory have been superseded by a collaborative understanding that respects both political authority and strategic military needs.

The US already operates the Pituffik Space Base in northwest Greenland and the new bases will allow “modernise and expand its activities” according to the US North Command, signalling an increase in American presence in the Arctic.
