In brief
In a landmark signing at the UN General Assembly, the United States, Denmark and Greenland agreed to allow Washington to establish two additional military bases in the Arctic territory. The deal, built on a 1951 agreement, designates Narsarsuaq in the south and Mestersvig in the east as potential sites and confirms that Greenland will remain a NATO-eligible territory. While the US gains a larger strategic footprint, the agreement preserves Denmark’s sovereignty and Greenland’s right to self‑determination. The pact marks a cooling of the tense Trump‑era standoff and an extension of NATO’s North Atlantic presence.
In a historic signing ceremony in New York, President Donald Trump, Danish Prime Minister Mette Frederiksen and Greenland’s head Jens‑Frederik Nielsen sealed a defence deal that lets the United States construct two new military bases on the Greenlandic island, while affirming Denmark’s sovereignty and Greenland’s right to self‑determination.
Under the pact, Washington may build a Defence Area at Narsarsuaq in the south and at Mestersvig in the east. The former was a WWII airfield and a former civilian airport used for deep‑water logistics; the latter, a remote outpost currently staffed by a Danish naval dog‑sled unit.
The agreement updates a 1951 defence treaty between Denmark and the US, giving reciprocal licence for the U.S. to station soldiers and modernise its existing pituffik Space Base in Greenland’s northwest. No territory is ceded; all bases must receive mutual approval from Denmark and Greenland.
Earlier this year, Trump had threatened to annex Greenland over security concerns, prompting protests across the Arctic. The new deal, which blocks non‑NATO forces from establishing a persistent presence, is seen by many as a diplomatic reset that preserves trans‑Atlantic alliances while expanding U.S. security infrastructure.
The signing was described by Danish officials as a “milestone” and “win‑win‑win” for the three parties, while NATO welcomed the pact as a boost to regional stability. Greenland’s leaders celebrated, relieved that months of uncertainty have ended and the island’s future is secure under the new pact.
