HA HA i'd never heard of that term before, i can remember being put in a Zugzwang on more than a few occasions by NGB at Chess.
I think the Nato Countries have a get out clause though Gringo, they can always put the Zugzwang in Ukraine's hands and pretend they haven't a say? I notice it is of German Origin, the fact that Germany is out of step with the US on Ukraine/Russia says alot
What you say is correct HB, the consequences of this abandonment though are what constitutes the Zugzwang that NATO are in. In a scenario where NATO do abandon Ukraine, obviously the Ukraine stage of this civilisational war ends almost immediately. There is no Ukraine without NATO/US money. But then what?
NATO having put everything they had into defeating Russia via Ukraine and being defeated will have huge ramifications. Who would want defending by NATO in light of this. The complete destruction of a country and its manpower to just walk away. Defeat in Ukraine would be the first significant step in ending the NATO alliance. Exposed as weak and merely the muscle for corporate and financial interests. NATO can't walk away from Ukraine without being shown as weak, powerless and humiliated by those actions. Also NATO cannot continue supporting Ukraine without being shown as weak, powerless and humiliated by those actions. They have no good move to make but must make a move.
That is the NATO zugzwang.
Russia have time and resources to spare.
