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.
