US and Denmark reach deal over Greenland’s security

Washington and Copenhagen Set New Security Framework for Greenland

Poinews.com – The United States, Denmark and Greenland are preparing to formalise a security agreement that places Arctic defence at the centre of their relationship, following months of tension over the strategically important island. The deal is expected to be signed during next week’s UN General Assembly gathering in New York.

US President Donald Trump said the arrangement would give Washington lasting authority over security matters involving Greenland. In a Truth Social post on Friday, he described the agreement as a major safeguard against foreign military and economic influence in the Arctic.

“I am pleased to announce that the United States of America has entered into an Agreement with The Kingdom of Denmark, and Greenland, that gives the United States permanent control over security.”

Trump said the agreement would prevent US rivals from establishing military installations, maintaining forces or making sensitive investments on the island without written permission from Washington.

“From now on, no U.S. adversary can EVER have a base in Greenland, have a military presence in Greenland, or make sensitive investments in Greenland, without our express written approval.”

Denmark stresses sovereignty and self-determination

Danish Prime Minister Mette Frederiksen welcomed the outcome while emphasising that Denmark’s sovereignty and Greenland’s political rights remain protected. Greenland is an autonomous territory within the Kingdom of Denmark, and its right to decide its own future has been a central issue throughout the debate over Arctic security.

“A great agreement for Greenland, the Kingdom of Denmark, and the United States.”

Frederiksen said the deal recognises “the sovereignty and territorial integrity of the Kingdom and the Greenlandic people’s right to self-determination.” She also presented it as an important contribution to collective security beyond the three parties involved.

“An agreement which strengthens our common security in the Arctic and the North Atlantic Area and therefore is great for NATO and Europe as well.”

Greenlandic Prime Minister Jens-Frederik Nielsen also gave his backing to the agreement, saying it would serve the interests of all sides and reinforce protection for the island.

“To the benefit of us all” and it would “ensure and strengthen the security of the island.”

Arctic security moves higher on the international agenda

The agreement follows repeated statements by Trump since returning to the White House in January 2025 that Greenland represents an essential US national-security interest. He has argued that Washington must ensure the island does not become vulnerable to Chinese or Russian influence, and previously threatened to take control of the Danish autonomous territory.

Those remarks prompted resistance across Europe and brought new attention to the Arctic’s role in defence planning. Greenland’s location between North America and Europe makes it significant for monitoring activity in the northern Atlantic and for early-warning systems. The region has also become more prominent in political discussions about military access, surveillance, infrastructure and investment.

For Denmark and Greenland, the new arrangement seeks to combine stronger cooperation with the United States and continued recognition of Greenlandic self-government. The public statements from Copenhagen and Nuuk point to an effort to frame security cooperation as a shared NATO and European priority, rather than a transfer of political control over the territory.

European Union investment plans

The European Union has also increased its engagement with Greenland as security and geopolitical concerns grow. European Commission President Ursula von der Leyen travelled to the island earlier this month and announced a €200 million partnership that is due to be invested this year and next year.

During the World Economic Forum’s annual meeting in Davos this year, von der Leyen said the EU was preparing a “massive European investment surge” for Greenland as part of its broader push to improve Arctic security. The European Commission has proposed €530 million for Greenland in its 2028–2034 budget, citing the territory’s expanding geostrategic importance in the Arctic.

These commitments underline that Greenland’s significance extends beyond defence sites alone. Decisions involving investment and major infrastructure can carry strategic implications in a remote region where access, communications and logistics are especially important. The proposed US-Danish-Greenlandic framework specifically addresses concerns over potentially sensitive foreign investments as well as military activity.

A long-standing US military presence

The United States has maintained a military role in Greenland for decades. At the height of the Cold War, it had 17 military facilities on the island and more than 10,000 troops stationed there. That presence has since been substantially reduced.

Today, the US operates one installation: Pituffik Space Base, the Department of Defense’s northernmost site. The base supports missile-warning, missile-defence and space-surveillance missions for the US Space Force. Its location gives it a key role in monitoring approaches across the Arctic and North Atlantic.

The forthcoming signing will provide the first detailed indication of how the new agreement translates the leaders’ broad declarations into practical security arrangements. Its political importance is already clear: it aims to reinforce Arctic cooperation among the United States, Denmark and Greenland while affirming Danish territorial integrity and Greenlandic self-determination.
