US, Denmark and Greenland seal Arctic security pact permitting new US bases
The United States, Denmark and Greenland have signed a security agreement that allows the US to build two new bases and expand an existing one in Greenland, pending parliamentary approval.
On Tuesday, the United States, Denmark and Greenland formalised a security arrangement that builds on a 1951 defence pact. The text permits the United States to set up two additional bases—one in southern Greenland at Narsarsuaq and another on the east coast at Mestersvig—and to enlarge the existing Pituffik Space Base. It also grants US aircraft and ships unrestricted fly-over, landing and under-sea access throughout Greenland’s territory and waters, though it does not detail troop numbers or timelines.
The agreement underscores support for a stronger NATO footprint in the Arctic and commits Denmark to reinforce its regional security posture, while stipulating that any future independent Greenland must remain within NATO. Greenland’s right to self-determination is affirmed, and the pact excludes investors from outside NATO, EU or partner states from controlling sensitive sectors, with Greenland tasked with screening such investments. The accord awaits approval from the Greenlandic and Danish parliaments and contains no expiration date, amendable only by mutual consent.
Why it matters
The pact determines future US military presence in the Arctic and links Greenland's security and investment rules to NATO and Western partners.
