The Greenland security agreement announced by Denmark, Greenland and USA would expand the American military presence in the Arctic while preserving the Kingdom of Denmark’s sovereignty and Greenlanders’ right to self-determination, according to the public statements released so far. The three governments expect to sign the agreement in New York next week, during the UN General Assembly, after months of negotiations over American security demands in Greenland.
The announcement is the breakthrough that Danish and Greenlandic officials had cautiously signalled in recent days. But the agreement has not yet been signed, its full text has not been published and the descriptions coming from Washington, Copenhagen and Nuuk differ on some of its most important implications. According to the Danish Prime Minister’s Office, it will also have to pass the necessary parliamentary procedures before entering into force.
What the Greenland security agreement says so far
US President Donald Trump was the first to announce the agreement, writing on Truth Social that it would give the United States “permanent control” over security and other American needs in Greenland.
“The United States will FOREVER have the complete ability to do what is necessary in Greenland in order to secure and defend the security of Greenland, and the United States of America.”
Trump also said the agreement would have no expiry date and that the USA would immediately begin developing a “large military presence” in Greenland.
According to his account, no American adversary would be allowed to establish a base or military presence in Greenland, or make sensitive investments there, without written approval from the USA.
These are, however, Trump’s descriptions of the agreement. The Danish and Greenlandic statements released so far do not specify what “permanent control” means, how large the additional American presence could become or what powers Washington would have over future investments.
Denmark and Greenland stress sovereignty and self-determination
The language used in Copenhagen and Nuuk places much greater emphasis on the limits of American authority.
Prime Minister (statsministeren) Mette Frederiksen said the agreement would strengthen security in the Arctic and North Atlantic while respecting the Kingdom of Denmark’s territorial status.
“The agreement strengthens our common security in the Arctic and the North Atlantic area and is therefore also good for NATO and Europe. At the same time, it recognises the Kingdom’s sovereignty and territorial integrity and the Greenlandic people’s right to self-determination.”
Chairman of Naalakkersuisut (Naalakkersuisut siulittaasuat) Jens-Frederik Nielsen said the agreement recognises Greenland’s interests and its place in international cooperation, calling the outcome beneficial for Greenland, Denmark, the USA and the Western alliance.
Greenland’s Minister for Foreign Affairs (Nunanut Allanut Naalakkersuisoq) Múte B. Egede, who participated in the trilateral working group, told DR that the agreement reflects the position Greenland has maintained throughout the negotiations.
“The agreement reflects what we have said from the start: Greenland’s position is recognised. Greenland’s right to self-determination is recognised, and the Greenlandic people are recognised under international law.”
The distinction matters because Trump had previously demanded American control or ownership of Greenland and, earlier in 2026, had not ruled out military pressure. Copenhagen and Nuuk consistently rejected those demands.
The different descriptions leave important questions open
The disagreement is now less about whether an agreement exists than about what the agreement actually allows.
TV 2 noted that the three governments have presented the outcome in notably different terms. Washington emphasises permanent American security powers, while Denmark and Greenland emphasise sovereignty, territorial integrity and self-determination.
The distinction will matter when the text becomes public.
The USA already has broad military access to Greenland under the 1951 defence agreement, later updated in 2004. Peter Viggo Jakobsen, associate professor at the Royal Danish Defence College (Forsvarsakademiet), told TV 2 that a larger American presence would therefore not necessarily mean that Washington has obtained entirely new military rights.
Marc Jacobsen, associate professor at the same institution, pointed instead to Trump’s claim that the new agreement would last indefinitely. If confirmed by the text, he said, that could represent an important change from the existing framework.
There are also unresolved questions about Trump’s statement that American approval would be required before adversaries could establish military facilities or make sensitive investments in Greenland. Neither Copenhagen nor Nuuk has yet explained how such provisions would work in practice.
Greenlandic reactions bring relief, but also caution
The first reactions among Greenlanders show why publication of the agreement will be important.
Julie Rademacher, chair of the National Association for Greenlanders (Landsforeningen for Grønlændere), told TV 2 that preserving Greenlanders’ right to self-determination and the Kingdom’s sovereignty was central to her assessment of the agreement.
Sara Olsvig, former Greenlandic MP and chair of the Inuit Circumpolar Council, said the announcement had reduced some of her concerns because the publicly stated terms appeared to respect those same red lines.
But DR’s interviews with residents in Nuuk recorded a more mixed response. Greenlanders are still reacting to political announcements rather than a published legal text, while the scale and location of any new American military presence remain unknown.
That uncertainty is especially relevant in Greenland, where the negotiations have involved not only defence policy but also control over the country’s future and its right to make its own political choices.
What the agreement could mean for Europe
From a European perspective, the agreement has two different dimensions.
The first is security. Frederiksen explicitly presented the agreement as strengthening NATO and European security in the Arctic and North Atlantic, at a time when governments across the region are paying greater attention to defence in the High North.
The second concerns the future of the transatlantic relationship. Trump’s earlier demands to control Greenland created a serious dispute between the USA and two governments inside the Western security architecture. The new agreement could bring that confrontation to an end without transferring Greenlandic territory or Danish sovereignty, if the final text confirms the assurances given by Copenhagen and Nuuk.
At the same time, the negotiations have highlighted a broader European concern: how to maintain American involvement in European security while preserving the ability of European governments and Greenland itself to make sovereign decisions.
The agreement therefore matters beyond Greenland. Its final wording will show whether a larger USA military role in the Arctic has been reconciled with the political red lines that Denmark and Greenland have defended throughout the crisis.
The final text will determine what has really changed
The announcement represents a significant shift from the confrontation that dominated relations between the USA, Denmark and Greenland earlier this year. It also follows months of negotiations through the trilateral working group established in January.
But several essential details remain unknown.
There is still no public information on the scale or location of the planned USA military expansion, the exact scope of the provisions covering foreign bases and sensitive investments, or how the agreement’s indefinite duration would operate. The date on which it could enter into force is also unclear.
Until the text is published and signed, the most important distinction remains between what Trump says the USA has obtained and what Denmark and Greenland say they have protected.
For Europe and Greenland, that distinction will determine whether the agreement is primarily an expansion of Arctic defence cooperation or a more substantial redistribution of authority in one of the region’s most strategically important areas.
