At least twice before that transaction, the U.S. had mulled buying Greenland, first as part of an unsuccessful plan in 1867 proposed by Secretary of State William H. Seward, who is now most remembered for buying Alaska from Russia in the same year.

One Danish Member of the European Parliament warned the United States is on a path to have “very few friends in the world.”

Danish Prime Minister Mette Frederiksen says an American takeover of Greenland would amount to the end of the NATO military alliance.

Sir Keir Starmer has warned Donald Trump that the future of Greenland must be decided by the people of the Arctic island and Denmark and not the US, in his first call to the White House since the US president’s intervention in Venezuela.

Greenlanders tell the BBC they have no interest in becoming American as the White House restates its desire for annexation.

Greenland's strategic location above the Arctic Circle makes it a focal point in global security and trade debates.

Danish soldiers will be required to shoot first and ask questions later if the United States invades Greenland, under the army’s rules of engagement.
