US, Denmark, Greenland Sign Defense Pact to Build Two New Military Bases
In a ceremony at the United Nations General Assembly in New York, the United States, Denmark and Greenland inked a defence agreement that permits Washington to construct two new military sites in Greenland, while reaffirming Copenhagen’s sovereignty and Greenland’s self‑determination. The treaty expands the long‑standing 1951 agreement, creating a Defence Area at Narsarsuaq in the south and the remote Mestersvig outpost in east Greenland.
President Donald Trump announced, “we will immediately begin the process of developing a large military presence in the appropriate locations,” signalling an accelerated build‑up that he says will counter threats from “adversaries, including Russia and China.” He had earlier hinted that the United States could take control of Greenland in light of its strategic geographical position and natural resources.
Prime Minister Mette Frederiksen called the deal “good for the US, Denmark and Greenland,” and for Europe and NATO. Greenland’s premier Jens‑Frederik Nielsen described it as a “win‑win‑win,” noting that it takes into account the livelihoods and development of the island’s 56,000 residents.
The new pact explicitly states that no state outside of NATO may establish “manned or unmanned military installations” in Greenland, and that Greenland could remain a NATO member if it ever becomes fully independent. The agreement also reaffirms the Danish Crown’s sovereignty and territorial integrity while recognising Greenland’s right to self‑determination.
Details of the bases’ construction, facilities and operational modalities remain to be agreed by all parties. The U.S. currently operates the Pituffik Space Base in Greenland’s northwest; the treaty will allow the nation to modernise and expand that installation. Meanwhile, the secrecy and scale of the new bases at Narsarsuaq—a former civilian airport with a long runway—and Mestersvig—a remote dog‑sled unit—have drawn attention.
Historians note that the deal ends more than a year of diplomatic tension following Trump’s attempts to annex the island. The U.S. sees the expanded presence as a strategic win, but the text remains cautious about ceding any territory, and the final approval will rest with Danish and Greenlandic parliaments.
The signing was celebrated worldwide, with NATO welcoming the agreement and referring to it as a means to “advance security, stability and cooperation in this vital region.” The treaty marks a significant shift in Arctic geopolitics, positioning Greenland as a critical hub for trans‑Atlantic defense while preserving its autonomy and sovereignty.
