Yes but Putin will have to conscript boys from the Elite in Moscow and St. Petersburg to get more fresh troops in Ukraine. So far, he hasn't done that. Right now, Ukraine is a special military operation. So the Russians think that the war is not really impacting them. But if Putin decides to mobilizes, then that will raise the stakes for everyone. The motivation is there in Ukraine. Russia? Not so sure about that.
They are only postponing the inevitable. There is no way Ukraine can win. Someone should initiate peace talks.
I have read that the Russian people overwhelmingly support Putin and the war in the Ukraine. Recall that this war started because of Ukraine's brutality to Russian speakers in eastern Ukraine.
