So as we move forward from this, I have very real concern as to whether Putin will do something drastic, and incredibly stupid, like drop a nuke on Kyiv. Not sure if that still sounds crazy (I had been brainstorming that a few days ago when it sounded crazier) but I really don't see Putin just say 'aw, gosh, sorry guys, guess we lost' and tucking tail. I also don't see a way he can spin this to make it look like a Russian victory. He doesn't serve a purpose of it isn't bringing benefit or glory to Russia, so I'm very concerned about him using the one card he'll have left at the end of everything.
And before everyone says 'Whhaaaattt? nooooo he'd never be that stupid!', a lot of people were saying the same goddamned thing before he walked troops in, defying the absolutely legendary level of economic (and military) destruction that we knew would fall on Russia if he did. And remember, at this time he has little to lose except his life, which might be forfeit anyhow.
