Donald Trump confirmed his interest in acquiring Greenland for the US, Denmark’s Prime Minister Mette Frederiksen said following a 45-minute phone call with the incoming US president on Wednesday.

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.

Denmark sent private messages to U.S. President-elect Donald Trump's team expressing willingness to discuss boosting security in Greenland or increasing the U.S. military presence there without claiming the island,

Donald Trump’s suggestion that he’d use force to acquire Greenland may just be bargaining. But for Denmark and Europe, it’s a possibility too serious to ignore.

The U.S. ally is signaling its willingness to negotiate military and economic matters related to the island but not to sell it.
