US and Denmark Sign Deal to Build Two Military Bases in Greenland
On Tuesday, President Donald Trump and Danish Prime Minister Mette Frederiksen signed a renewed defence agreement at the United Nations General Assembly that authorises the United States to construct new military installations in Greenland’s southern town of Narsarsuaq and the eastern outpost of Mestersvig.
The pact updates the original 1951 agreement, confirms that no territory is ceded to Washington, and explicitly bars any non‑NATO state from establishing a military presence on the island. Denmark’s sovereignty and Greenland’s right to self‑determination are reaffirmed as part of the deal, which Parliament will still need to approve.
Washington already maintains a base at Pituffik in Greenland’s northwest; the new agreement allows it to modernise and expand that site and to establish forward bases that could be critical for surveillance and early warning in the Arctic. Deterrence experts say the move strengthens NATO’s posture against emerging regional threats.
The signing was conducted by high‑profile statesmen amid a period of political tension; Trump had previously threatened to acquire Greenland for security reasons, prompting widespread criticism. The new treaty provides a diplomatic resolution while keeping the Arctic “in a friendly relationship.”
