Trump has shown interest in making Greenland part of the US and has not dismissed the use of military or economic power.

President Trump told Denmark’s leader he wanted to take over Greenland, European officials say. Denmark has asked its E.U. allies not to inflame the situation until Mr. Trump’s intentions are clearer.

Trump made it clear that he was "serious" about acquiring Greenland, but Danish PM Mette Frederiksen rejected the idea outright, stating Denmark was not interested in "selling" the mineral-rich island.
