Trump Plans Golden Dome Missile Defense System for Greenland

U.S. President Donald Trump said his administration is discussing the deployment of a “Golden Dome” missile defense system in Greenland as part of what he described as a developing framework with NATO covering Greenland and the wider Arctic.

In a Truth Social post, Trump said the framework followed a meeting with NATO Secretary General Mark Rutte and claimed it would benefit the U.S. and NATO allies. He said discussions were ongoing on the Golden Dome missile defense system “as it pertains to Greenland” and announced the suspension of U.S. tariffs of 10% to 25% on European allies, including Denmark, that were due to take effect on February 1.

Further, Trump said Vice President JD Vance, Secretary of State Marco Rubio, and Special Envoy Steve Witkoff would lead negotiations and report directly to him.

The NATO military talks reportedly explored hypothetical arrangements allowing the U.S. to establish sovereign military base areas inside Greenland, potentially modeled on the U.K.’s sovereign bases in Cyprus. Under such a model, the U.S. would exercise sovereignty over limited military zones rather than the entire island. It remains unclear whether Trump’s claimed framework formally includes such provisions.

NATO Secretary General Mark Rutte’s office rejected any suggestion that NATO had discussed sovereignty concessions. Greenlandic lawmaker Aaja Chemnitz said NATO has “absolutely no mandate to negotiate anything whatsoever without us in Greenland,” adding, “There is total confusion being created.” Denmark has so far not issued a formal response.

Trump has framed Greenland as central to U.S. national security, linking it directly to the Golden Dome initiative, a multi-layered missile defense system intended to counter ballistic, cruise, and hypersonic threats. Greenland’s location is viewed by U.S. planners as critical for Arctic surveillance and early warning.

According to The New York Times, the framework includes a U.S. pledge not to use military force to assert control, in exchange for expanded military access and economic concessions. Trump has insisted that ownership, even if limited to base areas, is required, saying, “You need the ownership to defend it. Who the hell wants to defend a license agreement or a lease?”

The proposal would require renegotiating the 1951 U.S.–Denmark defense agreement, which allows U.S. bases in Greenland while sovereignty remains with Greenland. A revised deal could give Washington greater autonomy to build systems such as the Golden Dome and impose legal restrictions blocking Chinese and Russian investment in Greenland’s ports, land, and mining sector.

Trump’s announcement followed remarks in Davos, Switzerland, where he said the United States would accept nothing short of U.S. “ownership of Greenland,” warning of economic and security consequences if negotiations fail and threatening further tariffs against Denmark and other European states.

Beyond security, Greenland holds large untapped reserves of rare-earth minerals, including lithium, neodymium, and graphite, critical for defense systems, electric vehicles, and advanced technologies such as artificial intelligence. The framework could likely include cooperation on mineral access, adding to concerns in Copenhagen and Nuuk over long-term sovereignty.

NATO said any negotiations would involve Denmark and Greenland directly and would aim to ensure that Russia and China “never gain a foothold — economically or militarily — in Greenland.”
