President Donald Trump said the United States should control Greenland rather than Denmark during a meeting on the sidelines of the NATO summit [1, 3].

The proposal creates a significant diplomatic rift between two key allies and raises questions about the stability of the North Atlantic Treaty Organization. Because the U.S. and Denmark are both members of the alliance, the suggestion of a territorial transfer, or the threat of force, challenges the core principle of mutual defense.

Trump cited the increasing activity of Russia and China in the Arctic as a strategic reason for the U.S. to take control of the island [1, 3]. Jeff Landry, the Louisiana governor and U.S. special envoy to Greenland, said Trump told him the U.S. needs to get Greenland [3].

Denmark responded to the proposal. Prime Minister Mette Frederiksen said that if the United States attacks Greenland, it would mean the end of NATO [2]. This response highlights the severity of the tension, as the Danish leader linked the preservation of the alliance directly to the sovereignty of the territory.

Reports on the potential for military action are contradictory. Some sources indicate that Trump said he would not use force to acquire the island [4]. However, other reports state that Trump threatened to remove U.S. soldiers from Europe if his demand for Greenland was not met [1].

Greenland's own leadership has also weighed in on the matter. The island's foreign minister said that the future of Greenland would be decided by its own people [1]. This emphasizes the local desire for self-determination regardless of the geopolitical interests of Washington or Copenhagen.

The discussions took place on July 7, 2026, in Washington, D.C., where the NATO summit was hosted [1, 3].

“Greenland should be controlled by the United States, not Denmark.”

This confrontation underscores a shift toward transactional diplomacy in U.S. foreign policy, where strategic Arctic assets are prioritized over traditional diplomatic norms. By linking the presence of U.S. troops in Europe to territorial gains in the Arctic, the administration is testing the resilience of NATO's collective security framework against the interests of individual member states.
