Five observations:
1. All of this was talked over back on Monday (Rubio comment). It was clear then....you arrive....friendly chat....sign the rare minerals understanding...no US participation in the ground situation or peace force....no entry into NATO.
Zelensky flies in....has breakfast with some Senators, and seems pepped-up to get a alternate deal at the White House. Takes about 15 minutes for Rubio to realize the guy has a totally different plan.
2. I don't think Trump will meet face-to-face with the guy again.
3. Lot of chatter in Ukraine....impeachment chatter. I kinda doubt that Zelensky is President by the end of March.
4. Europe worried? Well....they have no cards to play anymore.
5. The war is over....it may require a month to clear out the fronts....but it's got no more possible thrills.
