Greenland is 836,000 square miles of largely frozen ground northeast of Canada. So why does the White House say it "should be part of the United States"?

U.S. President Donald Trump has repeatedly threatened Greenland and says Washington must take control of the strategically located island

President Donald Trump has for years had his eyes set on the island, which he has repeatedly threatened to annex. Why?

The Danish territory is largely uninhabited, but the president wants to make it part of the U.S. because of its strategic location and rich natural resources.

Countries worldwide have eyes on Greenland for its natural resources, but the island only has one fully operational mine. We visited to find out why.

Political figures in Greenland have categorically dismissed President Donald Trump's continued efforts for the U.S. to take control of the island, maintaining that Greenland's future must be determined by its own citizens.

REEs such as niobium, tantalum and ytterbium have been discovered in igneous rock layers – similar to the discovery (and subsequent mining) of silver and zinc reserves in south-west England, which were deposited by warm hydrothermal waters circulating at the tip of large volcanic intrusions.
