At an Arctic security panel, Mette Frederiksen and Jens-Frederik Nielsen pushed back against renewed talk of Donald Trump seeking control of Greenland. Frederiksen called the pressure “unacceptable” and said red lines would not be crossed, while Nielsen warned that an ally attempting to acquire territory would undermine NATO unity and global order. He said Greenlanders felt unsafe for the first time due to such proposals, despite concerns about Russia and China in the Arctic. The exchange highlights rising geopolitical tensions in the region and growing focus on sovereignty, alliances and strategic competition.
