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.

The story goes that Trump and Frederiksen spoke on the phone last week for about 45 minutes in what was expected to be a bit of a feeling-out between the two parties, given Trump’s very public declaration that he would like to take Greenland off Denmark’s hands.

Despite Trump’s fervent claims that Greenland’s 55,000 residents desire to join the US, both Denmark and Greenland’s local leaders have firmly rejected the idea of a sale.
