So, how much of their country is Ukraine supposed to give up so Putin can save face? Putin started it...so him saving face his problem.
He has succeeded in turning parts of Ukraine into rubble. HE has succeeded in forcing millions to flee their homes. He likely will succeed in triggering a food crisis. I have a very hard time giving him some gift so he can save face.
If the Ukrainians are willing to fight for their country and the west is willing to supply the needed munitions, I think Russia is going to have an increasingly difficult time sustaining their munition supplies.
Our biggest mistake with Putin is we let him get away with many bad acts in the past, because we didn't want to provoke something larger.
