Trump Drops Greenland Annexation Demand as US and Denmark Reach Security Deal

US President Donald Trump announced on Friday that the United States has reached a security agreement with Denmark and Greenland, abandoning his earlier threats to seize the Arctic territory by force. The deal grants the US what Trump described as permanent control over Greenland’s security needs but leaves the island under Danish sovereignty.

Trump announced the agreement in a post on his Truth Social platform. He said the deal gives the United States ‘permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many US concerns.’

He also stated that the US would ‘immediately begin the process of developing a large military presence in the appropriate part of Greenland.’ The agreement bans US adversaries from establishing military bases or making sensitive investments in Greenland without American written approval.

Details Remain Limited

Danish Prime Minister Mette Frederiksen confirmed the agreement will be signed by the three governments next week during the United Nations General Assembly. She emphasized that the deal ‘recognizes the sovereignty and territorial integrity’ of Denmark and Greenland and upholds the right of the Greenlandic people to self-determination.

Frederiksen said the agreement ‘strengthens our common security in the Arctic and the North Atlantic area and is therefore also good for NATO and Europe.’ She added that the deal still requires parliamentary approval from both the Danish and Greenlandic governments before it can enter into force.

Greenland Prime Minister Jens-Frederik Nielsen said the agreement ‘recognises Greenland’s interests and our place in international co-operation. It is for the benefit of us all.’

Danish Foreign Minister Lars Lokke Rasmussen called the agreement ‘binding’ and said it ‘strengthens security’ in the Arctic. He wrote on Facebook that ‘next week could be a good week — for Greenland, Denmark and the United States.’

A NATO spokesperson said the alliance welcomed the agreement, which would ‘help advance security, stability and cooperation in this vital region.’

A Modest Outcome After Months of Tension

The agreement falls far short of Trump’s earlier demands. Since returning to office in January 2025, Trump repeatedly called on Denmark to sell Greenland to the United States and refused to rule out military force to take the island from the NATO ally.

Denmark and Greenland consistently rejected the idea, stating the island was not for sale and that sovereignty was non-negotiable. In January 2026, Trump backed down from threats to impose tariffs and use force, announcing a ‘framework’ agreement with NATO Secretary General Mark Rutte.

Negotiators from the US, Greenland and Denmark then spent months in closed-door talks. The resulting agreement appears to largely formalize and expand military cooperation that the US already enjoyed under a 1951 defense treaty.

Mikkel Runge Olesen, a researcher at the Danish Institute for International Studies, noted that under the existing agreement, the US military already had sweeping access to Greenland. He questioned whether the new deal achieved anything that could not have been reached without the crisis, asking, ‘Is there anything here that one could not have achieved without this crisis?’

Greenlanders Express Relief and Concern

In Greenland, reactions were mixed. Some residents expressed relief that the threat of annexation had receded. Others voiced confusion and skepticism about what the deal actually entails.

‘My immediate reaction is that it makes me nervous and skeptical,’ said Ellen Frederiksen, a retired teacher in Narsaq, southern Greenland. ‘The way Trump presents it, it sounds as if he is being given a monopoly over Greenland. I sincerely hope that isn’t the case.’

Aka Hansen, a filmmaker in Nuuk, said she had stored five days’ worth of water earlier this year in case of an American invasion. ‘Now, suddenly, everything is fine,’ she said. ‘What happened in between?’

Damage to Allies Persists

Analysts and commentators noted that while the agreement resolves the immediate crisis, the damage to trust within NATO and between the US and Denmark may be lasting. The Economist wrote on September 19 that the revised defense pact ‘is a modest improvement, but annexation threats were a costly blunder.’

Ed Arnold, a senior associate fellow and Arctic expert at the defense think tank RUSI, said the deal had achieved ‘very little – at great cost.’ He noted that the damage to NATO is already done and the agreement will do little to rectify it.

The six-month-old Iran conflict and domestic political pressures ahead of the US midterm elections in November have also reshaped the political context. Trump is seeking to present the deal as a foreign policy achievement, even as critics describe it as a climbdown from his earlier threats.

The agreement is expected to be signed next week at the UN General Assembly. The full text has not been released. Parliamentary approval in Denmark and Greenland remains pending.
