Danish Prime Minister Mette Frederiksen called the situation over Greenland a “decisive moment” after President Trump renewed threats to seize the Arctic territory by force.

She emphasized Denmark’s commitment to defending international law and Greenlanders’ right to self-determination, with Germany and Sweden backing Denmark against the U.S. claims.

European leaders warned that a U.S. takeover would violate international law and could set a dangerous precedent, while NATO officials discussed potential Arctic security operations.

The UK and other European countries are exploring plans to deploy troops, ships, and aircraft to protect Greenland from Russian and Chinese influence, Al-Jazeera has reported.

Greenland, which has self-rule and gained home rule in 1979, strongly opposes a U.S. takeover according to polls, and remains strategically important due to its mineral resources and Arctic location.
