On September 23, 2026, US President Donald Trump signed a new security agreement with Denmark and Greenland, allowing for an expanded American military presence on the Arctic island. The agreement was signed on the sidelines of the United Nations General Assembly in New York. Trump described the agreement as beneficial to the United States and Europe, stating it would be a "long-term, fantastic relationship."
The security agreement permits the US to establish new military facilities at Narsarsuaq in southern Greenland and Mestersvig in the east, while expanding and modernizing its existing Pituffik Space Base in the northwest. The pact also allows for expanded US military operations on the island, including broader access for American aircraft and other defense activities.
Despite the expanded US military presence, the agreement reaffirms the sovereignty and territorial integrity of the Kingdom of Denmark and recognizes Greenland's right to self-determination. This development comes after months of tensions over Trump's calls for greater US control of the territory, with Denmark and Greenland opposing the idea of the US acquiring Greenland.
Greenland's location in the Arctic makes it strategically important to the United States and NATO, particularly due to its proximity to North America and the shortest routes between North America and Russia. The territory is also rich in mineral resources and could become increasingly important as melting Arctic ice opens new shipping routes.
Danish Prime Minister Mette Frederiksen welcomed the agreement, stating that Denmark was in a better position following the deal. She expressed hope that the agreement would provide greater reassurance to Greenlanders after months of uncertainty. Greenland's Prime Minister Jens-Frederik Nielsen also supported the agreement, acknowledging that rebuilding trust at home would take time.
The agreement restricts non-NATO and non-EU countries from gaining a military or strategic foothold in Greenland, preventing them from establishing military installations or obtaining significant influence in sensitive sectors without approval. This provision is seen in the context of US concerns about the potential influence of Russia and China in the Arctic.
European officials, including European Council President Antonio Costa and German Chancellor Friedrich Merz, welcomed the deal as a positive step for transatlantic cooperation and Arctic security. The agreement builds on a 1951 US-Danish defense arrangement that was updated in 2004 and gives Washington significant military rights in Greenland.
