Plenty of people are rightfully mad about how the withdrawal went. I'd still have done that with improvements in method and process. They had to reorient resources to China and Russia.
They lack the ability to do dynamic targeting. That's due to deficiencies in training, systems and leadership. They never had low level leadership and the one organization that had any was Wagner and they just ripped the heart out of that outfit.
Sadly, this is jive. The objective was to get to the Black Sea coast and liberate Crimea. The problem was that Ukraine lacked Air Superiority and Russia was able to build defenses in depth enough to prevent this before the end of Summer. This offensive is a harbinger of Russia hitting a breaking point due to superior precision weapons destroying all their weapons systems but Ukraine needs to win decisively before changes in governments in the West eliminate their funding. I don't think the publics in the West are thinking along those lines but that is Ukraine's center of gravity as much as its population.
Ukraine appears to be on the right track but a lot of people will die before they get their victory.
Dabo is the hominid who saw the jawbone of the ass and told his players not to pick that evil thing up and had his clan of proto-humans wiped out by the clan that did pick up jawbones of asses.
Russia is sending these mobilized troops in with limited weapons and almost no training. That is not how you win. That's how you delay defeat. OTOH, Ukraine's best units and most motivated troops are getting over the 200 days of combat that combat mental health experts say is the "breaking point".

I hope Ukraine has been able to provide the same sort of rotation system.
There was a very interesting tweet the other day showing the home provinces of all the casualties suffered by the Russians. Not surprising was that Moscow and St. Petersburg were the lowest and the lower-status Tuva province was at the highest end by a lot. Putin's center of gravity are the elites and he doesn't want to send their kids or them (the conscription age is quite high) to war.
