The Danish PM's tour of three capitals betrayed the nervousness felt in Denmark over Trump's repeated comments.

Denmark’s prime minister is on a tour of major European capitals as the continent faces what she called “a more uncertain reality” and her country moves to strengthen its military presence around Greenland.

Danish Prime Minister Mette Frederiksen sought to drum up support from European allies to stand up to Donald Trump’s efforts to appropriate Greenland, as she tried to project unity while avoiding antagonizing the US president.

Until recently the most that people tended to know about cold and sparsely populated Greenland is that it is not small and also that it is not Iceland. It’s a frigid autonomous territory of Denmark, but self-governing.

U.S. President Donald Trump has repeatedly said that America needs to take control of Greenland from Denmark for, in his words, “international security.” But as Henry Ridgwell reports, the global attention is driving a desire among many native Greenlanders to determine their own political future.
