It’s much worse than that for Putin. There is video of Ukrainian civilians being issued rifles in Kharkiv today. That’s on the border practically IN Russia. Those type of places were a mess of Ukrainian corrupt in 2014. Now Putin is powerless to take them. He has lost.
Time for him to announce that he has reached his objectives and that he'll withdraw. Or he'll has to escalate. There's a risk of he ends up doing that.
