Danish Prime Minister Mette Frederiksen has warned that a potential American takeover of Greenland would signal the end of NATO, following comments from US President Donald Trump advocating for US control over the strategically important Arctic island. Frederiksen emphasized that any military action against a NATO member state would jeopardize the alliance and its long-standing security guarantees. Her remarks were made in light of a US military operation in Venezuela that has heightened tensions in Denmark and Greenland, which is a semi-autonomous territory. Amid rising concerns, both Frederiksen and Greenlandic leader Jens Frederik Nielsen reaffirmed their commitment to cooperation, rejecting any notion of a sudden US takeover. The situation highlights the fragility of international alliances and the evolving geopolitical landscape in the Arctic.
