Russia is in a tough spot. They need to hold the lower Dnieper to assure fresh water for the Crimea. The also want to keep their wide bridgehead on the western Dnieper.
I’d guess they’d rather lose additional territory in Luhansk then Kherson.
Another strategic alternative for the Russians would be for someone with a brain to throw Putin out of an upper story window.
Relax, they are evacuating citizens who are tired of being shelled constantly by Nazi’s. Why Americans are supporting Nazi’s is baffling to me, outside of the fact that the US media hides it completely.
