Trump Floats Military Option as US Pushes to Take Control of Greenland. The White House says President Donald Trump is weighing multiple options to bring Greenland under US control, including the possible use of military force — calling the Arctic island a national security priority. Greenland is a semi-autonomous territory of Denmark, a fellow Nato member, and Trump's comments have sparked sharp backlash across Europe. Leaders from the UK, France, Germany and several other countries issued a joint statement backing Denmark and stressing that Greenland's future can only be decided by its people. Trump argues the US "needs" Greenland for Arctic security, citing growing Russian and Chinese interest. Danish leaders have warned that any US attack would effectively destroy Nato unity. While US officials say talks and economic cooperation remain options, Greenlanders themselves overwhelmingly oppose becoming part of the United States, fearing their sovereignty is being treated as a bargaining chip.
