How does Putin get out of this?
1. He turns away removing his troops, with nothing to show for it.
2. Nato blinks, and gives Putin assurance that Ukraine will not be in Nato. Putin leaves troops in the area.
3. He invades parts of Ukraine where Russians currently live.
4. He initiates a coup in Ukraine putting in his own guy
I see a fifth option for Putin. It isn’t pretty for anyone “involved”.
