President Trump has made no secret of his designs on Greenland, repeating threats to acquire the territory through a financial transaction or military force.

Trump is also likely interested in the mining potential across Greenland's vast landmass, Mr Jacobsen added, especially the rare earth minerals in the south. During his speech to Congress, Trump said that control of Greenland was essential "for national security and international security."

P resident Donald Trump is ramping up his pressure campaign to make Greenland part of the U.S., even as Greenland's leaders insist that they are not interested and that the Danish territory is not for sale.

Greenland’s prime minister said a planned visit to the island by US officials, including second lady Usha Vance, is “highly aggressive,” plunging relations to a new low after President Donald Trump vowed to annex the autonomous Danish territory.
