Trump, Greenland, Denmark sign deal in bid to end Arctic standoff

The pact expands U.S. military access, bars non-NATO bases and sensitive foreign investments, and ties Greenland’s future NATO role to the agreement.

  • On Tuesday, September 22, 2026, President Donald Trump signed a new Arctic security pact with Danish Prime Minister Mette Frederiksen and Greenland Prime Minister Jens-Frederik Nielsen at the 81st United Nations General Assembly in New York.
  • The agreement follows months of diplomatic tension after Trump previously threatened to "take over" the autonomous territory via military force, citing national security concerns about Russian or Chinese influence.
  • Under the pact, the United States can "modernize and expand its activities" at Pituffik Space Base and establish new facilities in Narsarsuaq and Mestersvig to strengthen "common deterrence" against Arctic adversaries.
  • NATO Secretary General Mark Rutte hailed the pact as enhancing "our collective security," while Frederiksen praised the deal as "bigger and better" than the 1951 defense treaty between the Kingdom of Denmark and the US.
  • If disagreements arise, the deal requires parties to "immediately convene" for review within 90 days; it also reaffirms Danish sovereignty and bars non-NATO countries from controlling "Particularly Sensitive Sectors" like critical infrastructure.
