U.S., Denmark, Greenland to sign Arctic security pact
Trump is due to meet Danish PM Mette Frederiksen and Greenland PM Jens-Frederik Nielsen at the UN Tuesday to sign a deal expanding the U.S. military footprint beyond Pituffik, including sites at Narsarsuaq and Mestersvig. The full text remains unpublished ahead of signing.
President Trump, Danish Prime Minister Mette Frederiksen, and Greenland Prime Minister Jens-Frederik Nielsen signed an Arctic security agreement at the United Nations on Tuesday that expands the U.S. military footprint on Greenland while stopping short of Trump’s earlier demands for U.S. territorial control.
The text, released after signing, amends the 1951 defense treaty underpinning the U.S. presence at Pituffik Space Base. It opens two additional sites: Narsarsuaq, a former Cold War airbase, and Mestersvig, used by Denmark’s Sirius Dog Sled Patrol. Trump told the General Assembly the United States would begin developing “two very major military bases” and claimed “permanent control over security and all other needs” on the territory, barring adversaries from military presence or sensitive investments without U.S. written approval. The deal also contemplates a “Golden Dome” missile-defense role for Greenland and grants U.S. aircraft and vessels broad access across Greenland and its waters.
Frederiksen called it a deal that can “last forever,” stressing NATO and Greenlandic self-determination. Nielsen emphasized keeping NATO strong in the Arctic. A State Department official told ABC the pact “explicitly guarantees” U.S. ability to do what it deems necessary to secure the American continent and would remain in effect even if Greenland became independent; only the U.S. and allies could make sensitive investments. Rubio called it a historic win “at zero cost to the U.S. taxpayer.” Danish and Greenlandic officials said parliamentary approval is still required.
The agreement follows months of crisis after Trump refused to rule out force to acquire the island—rhetoric that rattled NATO allies. Coverage agrees the signing expands U.S. bases beyond Pituffik and preserves Danish sovereignty on paper. Conflict remains in framing: Trump describes permanent U.S. security control; Copenhagen and Nuuk present a NATO-aligned partnership that respects territorial integrity. The full operational details of “Golden Dome” deployment and future base requests will be tested in domestic ratification and Arctic politics.
Where outlets agree Parties confirm a Tuesday UN signing expanding U.S. access while Denmark and Greenland say sovereignty is respected.
Where they differ Trump says the deal gives the U.S. 'permanent control' over Greenland security; Danish officials emphasize NATO-shared Arctic responsibility and Kingdom sovereignty.
