The Story

Denmark and Greenland state any agreement with the United States will not compromise Greenland's sovereignty.

This statement follows President Donald Trump's assertion that a deal gives Washington permanent control over the Arctic island's security. The United States, Denmark, and Greenland announced late Friday they entered an agreement for the US to develop a military presence on Greenland. The agreement also prohibits US adversaries from building bases or having a military presence in Greenland, or making sensitive investments without Washington's express written approval.

Key details of the agreement remain undisclosed, including the extent of the US military presence and whether formal power over foreign policy and resources would be ceded. Denmark and Greenland express hope the deal, expected to be signed during the UN General Assembly next week, will end months of uncertainty. This uncertainty was triggered by Trump's earlier threats to seize control of Greenland.

Danish Foreign Minister Lars Lokke Rasmussen said on Saturday that next week could be a good week and that a time of uncertainty will hopefully give way to a binding agreement. Rasmussen added the agreement strengthens security in the Arctic and North Atlantic, and thereby shared security within NATO and Europe, while respecting the Danish Kingdom's red lines.

Danish Prime Minister Mette Frederiksen described the deal as recognizing the sovereignty and territorial integrity of the Kingdom and the Greenlandic people's right to self-determination. Trump, on Truth Social late Friday, said the United States will "FOREVER have the complete ability to do what is necessary in Greenland" to secure its security and that of the United States.

He also called it an "'Infinite Life' Agreement" with no end and said Washington would immediately start building a large military presence. Since returning to the White House in January 2025, Trump has repeatedly insisted Washington needed to control Greenland for strategic reasons, alarming NATO ally Denmark and sparking pushback from the alliance. Denmark and Greenland have repeatedly insisted Washington respect the sovereignty of the Danish kingdom and accept that Greenland is not for sale.
