Andrius Kubilius, a Defence Commissioner from the European Union, stated that a U.S. military takeover of Greenland would signify the end of NATO, aligning with Danish Prime Minister Mette Frederiksen's perspective. Kubilius expressed this view during a security conference in Sweden, emphasizing the negative implications for both NATO and public sentiment.

Greenland, an autonomous territory of Denmark, has been a point of interest for U.S. President Donald Trump, who has suggested that U.S. ownership of the island is crucial for national security, particularly to counter potential threats from Russia and China. Trump has indicated that a mere military presence in Greenland would not suffice to deter these nations.

Frederiksen has articulated that any military aggression by the U.S. against another NATO member would effectively dismantle the alliance and jeopardize the security framework established post-World War II. This statement marks a significant moment as it is the first public endorsement from a high-ranking EU official of Frederiksen's stance, although there is a consensus among EU diplomats that the U.S. is unlikely to resort to military force to acquire Greenland. Instead, they anticipate that the pressure exerted by the U.S. may lead to an enhanced military presence in Europe.

In a recent interview, Trump was posed a question regarding the prioritization of acquiring Greenland over maintaining NATO. While he did not provide a direct answer, he acknowledged the possibility that his administration might face a choice between the two.
