As I said, you equate Putin with Hitler.
I engaged in no such generalities. I observed a similar negotiating tactic; the use of a known psychological weakness on the part of an opponent to gain a negotiating advantage. Hitler did that, Putin appears to have done the same. And this is a way you play the game of international diplomacy, which a serious game played by adults for very high stakes. You use every advantage you can.
If you want to see more to it than that, you go right ahead.
