During a NATO summit in Ankara, Turkey, former President Donald Trump reiterated his longstanding push for the United States to take control of Greenland, arguing it should not remain under Danish authority. In response, Danish Prime Minister Mette Frederiksen issued a pointed warning, stating that NATO members are prepared to defend all allied territory, including Denmark’s own. Frederiksen reminded alliance members that the organization was founded on mutual defense commitments. The exchange highlights ongoing tensions between the U.S. and a close European ally over sovereignty of the Arctic island, which hosts strategic military assets and significant natural resources. The dispute emerged at a key gathering of NATO leaders, underscoring broader alliance cohesion concerns.
