The White House has kept all options for acquiring Greenland on the table, refusing to rule out military action.

Allies including France and Germany are working closely on a plan on how to respond should the United States act on its threat to take over Greenland.

Countries in Europe reportedly are working on a plan if the Trump administration makes a move on acquiring Greenland, which is a a Danish territory.
