Trump Signs Greenland Security Agreement

NEW YORK — President Donald Trump signed a new security agreement with Denmark and Greenland on September 22, establishing long-term arrangements for expanded U.S. military access and operations across Greenland.

The agreement was signed at United Nations headquarters in New York by Trump, Danish Prime Minister Mette Frederiksen and Greenlandic Prime Minister Jens-Frederik Nielsen.

Unlike earlier discussions about U.S. ownership of Greenland, the agreement does not transfer sovereignty to Washington. Denmark and Greenland remain responsible for the territory under the existing constitutional framework.

The document explicitly reaffirms Denmark’s sovereignty and territorial integrity while recognizing Greenlanders’ right to self-determination under international law.

At the same time, the agreement gives the United States substantially broader military access, including rights involving Greenland’s territory, territorial waters, airspace and existing defense areas.

The United States will be permitted to modernize and expand operations at Pituffik Space Base, a strategically important installation located in northwestern Greenland.

The agreement also provides for two additional U.S. defense areas at Narsarsuaq and Mestersvig, subject to technical arrangements between the participating governments.

Washington can also propose additional defense areas in Greenland, although the agreement establishes consultation procedures requiring the parties to negotiate implementation details.

U.S. aircraft will receive broad rights to fly over and land in Greenland, while American public vessels will have specified access to Greenlandic territorial waters.

The agreement also allows the United States to establish or operate unmanned military installations outside designated defense areas through an accelerated approval process.

A major provision concerns the agreement’s duration. The document states that it has no end date and can only be amended through mutual consent under the existing defense framework.

The agreement further addresses a possible future in which Greenland becomes independent. In that scenario, the document says Greenland would assume the rights and obligations currently held by Denmark under the agreement.

It also requires an independent Greenland to remain within NATO, either by continuing membership or applying for membership if necessary, according to the signed text.

Another provision restricts non-NATO states from establishing military installations or maintaining a persistent military presence in Greenland unless the parties agree otherwise.

The agreement also places restrictions on certain foreign investments in sensitive sectors when investors from outside NATO, NATO partners or the European Union could create national-security or public-order concerns.

The White House described the arrangement as giving Washington lasting control over Greenland’s security interests, while Danish and Greenlandic officials emphasized sovereignty, self-determination and NATO cooperation.

The deal follows months of tension after Trump repeatedly argued that Greenland was strategically important to American national security and had discussed acquiring the territory.

The new arrangement instead creates a formal security framework that expands the American military footprint without changing Greenland’s status as part of the Kingdom of Denmark.

Reuters reported that the agreement is intended to strengthen the U.S. position in the Arctic while addressing concerns about growing Russian and Chinese strategic activity in the region.

Greenland’s strategic importance comes from its location between North America and Europe, its proximity to Arctic shipping routes and its potential access to strategically important mineral resources.

The agreement still requires the completion of necessary parliamentary procedures before entering into force, according to the Danish government.

For now, the September 22 signing represents a significant change from the earlier dispute over whether the United States could acquire Greenland, replacing territorial acquisition discussions with a long-term defense and security arrangement.
