Donald Trump is considering options for acquiring Greenland, including military action, which could have severe implications for NATO. While some analysts suggest a military operation could be feasible, many believe it would violate international law and face significant resistance. The U.S. has expressed interest in purchasing Greenland, but this would require Congressional approval and Greenland's participation. Public opinion in Greenland leans towards independence from Denmark, and any U.S. influence campaign may be more viable than military action.
