US, Denmark Reach Deal on Greenland Military Presence

The United States, Denmark and Greenland announced late Friday that they have reached a landmark agreement allowing Washington to develop a significant, permanent military presence on the strategically vital Arctic island, while barring US adversaries from establishing their own bases there.

President Donald Trump, Danish Prime Minister Mette Frederiksen and Greenland Prime Minister Jens-Frederik Nielsen confirmed the deal, which is expected to be signed next week during the United Nations General Assembly but still requires parliamentary approval in both Denmark and Greenland before it takes effect, according to NPR and The Associated Press.

A Shift From Threats to a Deal

Trump announced the agreement in a social media post, saying it gives the United States “permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many U.S. concerns.” He added that his administration would “immediately” begin developing a larger military presence on the mineral-rich Danish territory.

The deal caps months of tension triggered after Trump, upon returning to the White House in January 2025, renewed calls for Denmark to sell the island and refused to rule out taking it by military force — even though Denmark is a NATO ally. Denmark and Greenland repeatedly stated the island was not for sale.

Officials from all three governments quietly negotiated for months, with a high-level working group established in January 2026 following a meeting in Washington, D.C.

What the Agreement Covers

According to a State Department official who was not authorized to comment publicly and spoke on the condition of anonymity, the agreement bans any non-NATO base in Greenland, limits adversaries from making investments in Greenland, and guarantees that China and Russia cannot have a base on the island.

As Fox News reported, the deal grants the US permanent access, basing and overflight rights, along with the ability to establish additional military installations as needed. Under the new terms, Denmark and Greenland would not hold approval authority over additional US installations; the US would consult with them but retain the right to build when it deems necessary.

The agreement has no expiration date and is designed to remain in effect even if Greenland eventually becomes independent. Crucially, it does not transfer sovereignty over Greenland to the United States.

“This historic deal is a huge win for the United States and the American people,” Secretary of State Marco Rubio said. “Greenland will forever be part of the strategic defense area of North America and exclude any adversary from it and the surrounding area. This deal permanently and completely addresses our national security concerns in Greenland.”

Sovereignty Preserved, Officials Say

Danish and Greenlandic leaders emphasized that the deal upholds their sovereignty and territorial integrity — a central sensitivity given that Copenhagen has governed Greenland for roughly 1,000 years.

Frederiksen said the agreement “recognizes the sovereignty and territorial integrity” of Greenland and Denmark and upholds both peoples’ right “to self-determination.” In a joint press release, she added that the deal “strengthens our common security in the Arctic and the North Atlantic area and is therefore also good for NATO and Europe.”

Nielsen said the agreement benefits all three governments and “recognizes Greenland’s interests,” writing that it affirms the right of the Greenlandic people to self-determination.

Danish Foreign Minister Lars Løkke Rasmussen struck an optimistic tone, saying in a statement that “next week could be a good week – for Greenland, Denmark and the United States,” and expressing hope that “a time of uncertainty will hopefully give way to a binding agreement.”

An Existing Presence, Expanded

Despite the shift in scale, the United States is not newly entering Greenland. It has operated there since World War II, when it occupied the island to prevent it from falling to Nazi Germany and to protect North Atlantic shipping lanes.

The two countries signed the Defense of Greenland Treaty in 1951, granting the US broad freedom to operate military installations. The US still operates the remote Pituffik Space Base in northwestern Greenland, which supports missile warning, missile defense and space surveillance operations for the US and NATO.

Greenland sits off the northeastern coast of Canada, with more than two-thirds of its territory lying within the Arctic Circle — a location that has made it crucial to North American defense. The island is home to roughly 56,000 residents and holds significant mineral and rare-earth resources.

In January 2026, European NATO member nations sent military personnel to Greenland to demonstrate military readiness, and eight European allies issued a joint statement confirming their commitment to Arctic security.

Strains and Questions Ahead

NATO welcomed the agreement, with a CNBC report quoting spokesperson Allison Hart saying it would “help advance security, stability and cooperation in this vital region.”

But analysts caution that the deal does not erase the damage done to US relations with Europe during months of threats. “I think Americans really underestimate how damaging it was for the image of the United States in Europe,” said Imran Bayoumi, an associate director at the Atlantic Council’s Scowcroft Center for Strategy and Security. “I think Greenlanders, Danes, Europeans saw this as a real attack on their sovereignty, and it’s going to take a lot of work to repair.”

As The Guardian reported, Mikkel Vedby Rasmussen, a political science professor at the University of Copenhagen, said the deal “is probably not the end of President Trump’s ambitions for Greenland and certainly not the end of US strategic interest in the territory and its resources.” He added that if Copenhagen cedes any formal power to Washington over Greenland, it would raise questions for Greenlanders of whether “this is the beginning of replacing the colonial relationship with Denmark with a colonial relationship to the United States.”

Key details remain undisclosed, including the precise scale of the expanded US military presence and whether any formal authority over foreign policy and resources will be ceded to Washington.

What’s Next

The agreement is expected to be signed next week at the UN General Assembly, but it is not yet binding. Parliamentary action is still required in both the Danish and Greenlandic governments before it can be enforced.

For Trump, the announcement offers a foreign policy achievement ahead of the midterm elections, even as his administration manages an ongoing conflict with Iran and a military operation in Venezuela. Danish political analyst Jens Ringberg, speaking to DR, called it “certainly historic” that an agreement could be reached while pressure remained on both Denmark and Greenland.

For Denmark and Greenland, the coming parliamentary debates will determine whether the deal delivers the security guarantees and sovereignty protections their leaders have promised — or whether the underlying tension resurfaces. Analysts on both sides of the Atlantic will be watching closely to see how the agreement is implemented, and what it means for the future of Arctic security.
