Greenland, which US President-elect wants to annex, is a self-governing Danish territory covered in ice, with untapped mineral resources -- and geostrategic importance. In December, Trump said control of the Arctic island was "an absolute necessity" for "purposes of National Security and Freedom throughout the World".

U.S. President-elect Donald Trump says he wants to make Greenland a part of the United States and does not rule out using military or economic power to get Denmark to hand over the mineral-rich and strategically important island.
