Nah, I don’t buy into it he so called appeasement lesson from WW2. I think people misread that whole situation.

I think it is pretty naive to think you can threaten Putin with a stick and they makes him back down. People grossly overestimate the effectiveness of threats and violence. In WW2 both Germany and British terror bombed each other thinking it would break moral. It did pretty much the opposite.

What you suggest is a dangerous receipt to escalate a tense situation. We should instead drive-escalate.

There is a real lesson from WW1 and that is that escalation can eventually lead to war.

There is no reason to think Putin wants to occupy all of Ukraine. If he invades it will be to pressure the Ukraine and the West to the negotiation table.

Of course this will be an idiotic move because few people in the West will see it that way. But hey, that is the world we live in. People do stupid things and people misinterpret those stupid things.
