Denmark, Greenland, and the United States are scheduled to sign a security agreement at the United Nations General Assembly in New York, shifting oversight of the Arctic island’s defense responsibilities largely to NATO.
Shifting Arctic Security to NATO
Danish Foreign Minister Lars Lokke Rasmussen told national broadcaster TV2 that security responsibility in the region will no longer rest solely on Denmark and the United States. Instead, Rasmussen noted that NATO will take on a major role in looking after the Arctic.
A NATO spokesperson stated that the alliance welcomes the agreement, highlighting that it will help advance security, stability, and cooperation in the vital region. While key operational details of the draft have not been made public, Rasmussen confirmed to the Danish news agency Ritzau that Copenhagen entered the talks open to accommodating legitimate U.S. security interests.
Defusing Months of Diplomatic Pressure
The agreement follows a period of heightened tensions sparked by pressure from Washington. President Donald Trump previously asserted that the United States should control Greenland, at times declining to rule out using military or economic force to acquire the semi-autonomous territory. Those demands triggered a diplomatic crisis within NATO and pushed Danish and Greenlandic leaders into direct negotiations with U.S. officials.
Trump claimed in a post on Truth Social that the agreement grants the United States permanent control over security and other needs in Greenland, adding that no adversary could establish a military presence on the island without Washington’s written approval. Neither Denmark nor Greenland has formally commented on Trump’s specific claims of permanent control, though Copenhagen has previously acknowledged decades of underinvestment in the island’s defense and pledged to expand its military footprint alongside NATO troops.
Local Reassurance and Regional Oversight
Government officials in Greenland have moved to reassure residents regarding the terms of the pact. Erik Jensen, an opposition lawmaker in Greenland, stated on Facebook that he had read the draft agreement and felt reassured rather than worried, praising the territory’s foreign minister for handling the negotiations effectively.

The agreement remains centered on updating defense arrangements for the strategic island, though officials have not clarified whether it formally amends the foundational 1951 defense agreement that currently governs the U.S. military presence in Greenland.
