“Dangerous? Like what is Greenland going to do about it??”
No reason for ruff stuff.
Just send 50,000 Americans there uninvited, have them register to vote, and take over at the ballot box.
That is the way Mexico took back control of California.
Just deport all our illegal aliens to Greenland until they beg us to join the US so we can deport them out of Greenland.
Just drop them off and sail away.
