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.

Donald Trump has lashed out at the Danish Prime Minister during a "horrendous" 45-minute phone call as the duo discussed Greenland's future. The heated discussion has been described as "explosive" and was driven by Trump's demand that securing Greenland was required for national security purposes.

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.
