Greenland Prime Minister Jens-Frederik Nielsen said the island and its people should be prepared for “everything,” not ruling out a U.S. military action as President Donald Trump doubles down on taking control of the semi-autonomous Arctic island, part of Denmark, writes CNBC.

Speaking at a news conference, Nielsen said that while the scenario was unlikely, Greenland has to be prepared as “the other side” has not ruled out the use of military force, in an apparent reference to the US: “It is not likely that there will be a use of military force, but it has not been ruled out yet. This leader from the other side has made it very clear that it is not ruled out. And therefore we must of course be prepared for everything”.

Nielsen said that Greenland’s government was preparing an information campaign for its people, including guidelines on what individuals can do, including recommendation to have at least 5 days of food in their homes. Greenland will also be forming an emergency response team consisting of departments from municipal authorities, the police and Denmark’s Joint Arctic Command. “We must emphasize that we are in a difficult, a difficult time, a stressful time, and we cannot rule out that it can escalate even [to something] worse”, - Nielsen said.
