General Discussion

It's an attempt at division of the world for the next hundred plus years.
Europe goes to Russia, and Greenland down to S.A. goes to the US. China gets Asia.
They don't care if it's unpopular. Trump wants the US unpopular so Europe doesn't want to ask for help with Russia anymore.
Europe will be allowed to bulk up a bit and to feel it doesn't "need" US support, and that's when Putin will move.
Trump will invade Greenland as a "buffer" against the new war engulfing Europe (as the prudent thing to do without, Congress).
China gets Taiwan after that, because we're busy in Greenland. Trump never played well in Asia so "Eff 'Em".
If China gets jumpy, we have new resource reserves to throw into a war in the Pacific, and a dedicated gas station (Venezuela) protected by the Panama canal.
Hawaii is probably "tainted" by Obama, and is golf resort competition, so I bet China gets it without much effort.

Check back in 2036 to see how much I got wrong...
