Danish Prime Minister Mette Frederiksen says an American takeover of Greenland would amount to the end of the NATO military alliance. Her comments come in response to U.S. President Donald Trump’s renewed call for the strategic, mineral-rich Arctic island to come under U.S. control in the aftermath of the weekend military operation in Venezuela. The dead-of-night operation by U.S. forces in Caracas to capture leader Nicolás Maduro and his wife early Saturday left the world stunned, and heightened concerns in Denmark and Greenland, which is a semiautonomous territory of the Danish kingdom and thus part of NATO.
