According to information drawn from classified documents of Denmark’s Ministry of Defence, U.S. military personnel were secretly monitoring Greenland and Danish military facilities on the island as early as 2025. The findings were reported by the Danish newspaper Berlingske.

The publication notes that heavily redacted materials indicate that American servicemen were allegedly collecting data on critical infrastructure directly on Greenland’s territory. The documents suggest that this activity focused on strategically important sites.

The report’s authors point out that the U.S. military sought to obtain information on key facilities-including ports, airfields, and military bases in Greenland-without the consent of Copenhagen. This, they emphasize, marked an attempt to gather sensitive intelligence outside established agreements.

Local command structures reportedly reacted promptly, informing Denmark’s senior military leadership about what was viewed as a spying attempt. Experts cited by Berlingske have voiced concern that such actions could signal further U.S. intelligence operations in the region.

In Copenhagen, the episode is seen as particularly alarming. Danish officials fear the incident may be linked to broader U.S. plans involving political pressure-or even the use of force-against Greenland.

The revelations come amid earlier remarks by former NATO Secretary General Anders Fogh Rasmussen, who sharply criticized U. S. President Donald Trump. Rasmussen argued that the American leader communicates in a confrontational, almost gangster-like manner and described Trump’s focus on Greenland as a tool to distract attention from more serious global threats.
