US Amends Defense Treaty with Denmark and Greenland Regarding Military Presence

Idaho Falls Pocatello, ID, September 23, 2026 —

The Trump administration has executed a supplementary defense agreement with Denmark and Greenland. This agreement amends the existing 1951 treaty that governs the United States military’s presence in Greenland.

Key provisions within the new accord include a prohibition on non-North Atlantic Treaty Organization (NATO) countries from establishing military bases in Greenland. The agreement also reportedly permits the construction of two additional US military bases on the island. Furthermore, it establishes provisions to ensure continued US military access to Greenland in the event of Greenland’s independence.

According to the summary provided, experts have indicated that the supplementary defense agreement is expected to result in only minor modifications to the current US military posture in Greenland. Specific details regarding the timeline for the construction of new bases or any potential changes to existing infrastructure were not provided. The exact nature and scale of the US military footprint governed by the 1951 treaty and its amendments remain central to the understanding of this defense pact.

The 1951 treaty originally established the framework for US military facilities in Greenland, most notably the Thule Air Base. This new supplementary agreement updates the terms of that long-standing defense relationship between the United States, Denmark, and Greenland, a self-governing territory within the Kingdom of Denmark. The full implications and operational changes stemming from the agreement are subject to ongoing assessment.
