Former NATO Secretary General and former Danish Prime Minister Anders Fogh Rasmussen warned Donald Trump that an attempt to conquer the Danish territory of Greenland would be the end of the Western alliance,

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

It is the strongest statement by a leader of the Danish territory since US President Donald Trump renewed plans to annex it.

Mette Frederiksen said she would “strongly urge that the United States stop the threats against a historically close ally.”

Canada "stands firmly" with Greenland and Denmark, Prime Minister Mark Carney said Tuesday, after US President Donald Trump vowed his plan to take control of the autonomous Danish territory was irreversible.

President Trump said on Jan. 21 that he would not use military force to take control of Greenland, offering some relief to residents who had feared such a move.
