Greenland must make its own decisions about independence from Denmark, Prime Minister Mette Frederiksen told President-elect Trump in a Wednesday phone call. The big picture: Trump, since his first term, has repeatedly floated the idea of the U.S. buying Greenland even though the island's leaders have said it is not for sale.

Copenhagen has been deliberating over how to respond to statements by US President-elect Donald Trump about his desire to annex Greenland, amid indications that these remarks are not merely jokes. Danish officials have reportedly received signals from Trump's advisors and allies suggesting that he is serious about his plans.
