Seriously, the situation in Ukraine can't really be salvaged, keep dumping mobilised troop in place won't change anything, tey need time to rearm, regroup and retrain their troop before they make another big push.
They may as well, just withdraw everywhere and then regroup and come back after winter...
Honestly, even after regrouping, training, and arming, it’s no good for the Russians. Ukraine is armed to the teeth, and the worst enemy you can fight is the one that is fully alert and analyzing all threat parameters.
The Russians are emperors without clothes.
This war is lost, and Russia is relegated to local power, not even a regional one.
The US also played a risky game cornering Russian and calling its bluff, and succeeded and effectively showed the Europeans had no clothes. Had it not been for US arms, Intel, etc., and NATO cover, they would've been spanked around.
