Trump Signs Trilateral Deal Expanding U.S. Military Presence in Greenland
Donald Trump signed a security agreement with Denmark and Greenland to establish new military bases and block Russian and Chinese influence in the Arctic.
On September 22, 2026, Donald Trump signed a trilateral security agreement with Danish Prime Minister Mette Frederiksen and Greenlandic Prime Minister Jens-Frederik Nielsen during the UN General Assembly in New York. The pact ends a diplomatic crisis sparked by Trump's repeated attempts to acquire the mineral-rich territory, which included threats of military force and import tariffs against European allies.
The agreement authorizes the United States to modernize the Pituffik Space Base and establish two new military installations at Narsarsuaq in the south and Mestersvig on the east coast. These sites will support the proposed Golden Dome missile defense system and monitor the GIUK gap to contain the Russian Northern Fleet. The deal grants the U.S. permanent control over security needs and unrestricted military mobility, including undersea access, while explicitly barring non-NATO adversaries—specifically Russia and China—from establishing bases or making sensitive infrastructure investments.
While Trump characterized the accord as providing "permanent control over security," the document reaffirms Danish sovereignty and Greenland's right to self-determination. Notably, the agreement remains binding even if Greenland achieves independence, provided the new state remains a member of NATO. Greenlandic leaders viewed their role as direct signatories for the first time as a victory for autonomy. Following the signing, Denmark expressed hope that the Arctic Sentry mission's heightened patrols would become a permanent NATO fixture to counter geopolitical competition in the region.
