A new Greenland security deal between the United States and Denmark has eased a major diplomatic dispute after months of threats from President Donald Trump to take control of the strategically important Arctic territory. The agreement is expected to be signed at the United Nations General Assembly next week, although its full text has not yet been published.
The proposed arrangement involves the United States, Denmark and Greenland, and is intended to strengthen defence cooperation across the Arctic and North Atlantic. Leaders have stressed that the agreement recognises Denmark’s sovereignty and Greenland’s right to self-determination.
Greenland security deal promises stronger Arctic defence
Trump said the agreement would provide the United States with permanent control over Greenland’s security and related needs. He described it as a cost-free arrangement that would allow Washington to take measures it considers necessary to defend the territory.
According to a US State Department official, the framework could give the United States permanent access, basing and overflight rights. The official also said Washington would be able to construct additional military facilities without seeking approval from Greenland or Denmark.
Other reported provisions include:
- A ban on non-Nato countries establishing military bases in Greenland.
- Restrictions on investments by foreign adversaries in sensitive sectors.
- Measures aimed at preventing Russia and China from deploying troops or expanding strategic investments.
- Continuation of the agreement even if Greenland becomes independent in the future.
Because the official agreement has not been released, it remains unclear how these proposals differ from the existing 1951 defence arrangement, which already allows the United States to station forces in Greenland.
Denmark and Greenland welcome agreement while protecting sovereignty
Danish Prime Minister Mette Frederiksen said she was pleased that a constructive agreement appeared possible. In a joint statement with Greenlandic Prime Minister Jens-Frederik Nielsen, she said the deal would strengthen security in the Arctic and North Atlantic while respecting the sovereignty and territorial integrity of the Kingdom of Denmark.
Nielsen said the arrangement recognised Greenland’s interests and its role in international cooperation. Danish Foreign Minister Lars Lokke Rasmussen also welcomed the announcement, while emphasising that any final agreement must respect Denmark’s established red lines.
The deal will need to pass the necessary parliamentary procedures after signing before it can formally enter into force. The lack of a publicly available text is likely to prompt further debate in Denmark and Greenland.
Why Greenland matters to the United States
Greenland occupies a highly strategic position between North America and Europe. Its location makes it important for missile detection, military logistics, air surveillance and monitoring activity across the Arctic.
The United States already maintains Pituffik Space Base in north-west Greenland, where more than 100 American military personnel are permanently stationed. Washington has argued that greater access is necessary to respond to potential threats from Russia and China.
Trump has also linked Greenland to his proposed Golden Dome missile defence system. The island’s extensive, largely untapped reserves of rare earth minerals add another layer of importance, as these materials are used in mobile phones, electric vehicles and other advanced technologies.
Greenland’s political future remains central
Although the agreement is presented as a security framework, Greenland’s political status remains a sensitive issue. The territory is self-governing but part of the Kingdom of Denmark, and its leaders have repeatedly asserted that decisions about Greenland’s future should be made by Greenlanders.
Reports that the proposed deal could remain valid if Greenland eventually becomes independent underline the long-term significance of the arrangement. Any expansion of US military access is likely to be examined closely by Greenlandic politicians, residents and other Nato members.

Nato welcomes Greenland agreement
Nato said the deal could advance security, stability and cooperation in an important region. US Secretary of State Marco Rubio called it a historic agreement and said it addressed Washington’s national security concerns.
However, the dispute has already damaged relations between the United States, Denmark and Greenland. Trump’s earlier calls to purchase or annex the territory triggered protests in Greenland and criticism from Denmark and other Nato allies.
The final impact of the agreement will depend on its published terms, parliamentary approval and how Greenland’s government interprets the balance between security cooperation and political autonomy.
