It was a contentious, aggressive telephone call, five days before the inauguration of President Donald Trump on Jan. 20.

Trump has said Denmark would be committing a 'very unfriendly act' if it did not allow the US to take over Greenland. What's behind the US President's increasingly aggressive bid for a snow-covered island?

Trump has a price, and the billionaires filling Trump’s cabinet and his pockets are willing to pay it for a chance to line their own.

There was even a 'horrendous' phone call between Trump and Danish prime minister Mette Frederiksen that left officials in Denmark who'd been wondering how seriously to take Trump's rhetoric 'utterly freaked out' as they realised the US has a 'serious, and potentially very dangerous' interest in acquiring Greenland.

Speaking aboard Air Force One, Donald Trump declared “I think we’re going to have it" when asked about his plans of purchasing Greenland.

How earnest is Donald Trump? Does the president dream of stealing new territory for America? How maniacally imperialist will this administration be? As with anything Trump says, it’s difficult to know.

Anders Vistisen, a Danish member of the European Parliament, has told U.S. President Donald Trump to "f*** off" after Trump again expressed interest in purchasing the island of Greenland. Newsweek has contacted the White House for comment via email.

Denmark would need to offer Greenland to the UK first before the island could be sold to Donald Trump, it has emerged. An agreement dating back to 1917 means Britain has first refusal on the Arctic island if current owners Denmark decide to sell it, according to Tom Høyem, Copenhagen’s representative in Greenland from 1982 to 1987.

President Donald Trump has said he believes the US will gain control of Greenland, after showing renewed interest in acquiring the autonomous Danish territory in recent weeks. "I think we're going to have it," he told reporters on Air Force One on Saturday, adding that the island's 56,000 residents "want to be with us".

President Donald Trump had European officials scrambling after he reportedly told Denmark he was dead serious about taking over Greenland

Danish officials, who wished to stay anonymous, spoke to the Financial Times after Trump had a call with Danish Prime Minister Mette Frederiksen. They claimed the president was fiery, aggressive, and confrontational, despite the offer to increase Greenland-US cooperation on military bases and natural resources.
