This indicates that Ukrainian efforts at attrition warfare have delivered over the summer, and that they're well positioned to start up manoeuvre warfare again.

It's worth saying that these elite Russian forces are about as well-equipped and trained as Ukraine's offensive brigades. There were some fairly well researched reports from last year by the ISW about how these air assault divisions have been getting badly beaten up since the start of the war, and have taken significant losses on multiple occasions against regular Ukrainian troops. Not to write them off completely, but the Ukrainians are perfectly capable of taking on these guys.

There is tangible evidence Ukraine's push south is working. There is no evidence they're failing on the eastern front. Forbes, please explain to me why forcing Russia's last reserves to reposition is a "screw up."

Maybe this is intentional, and they will hit them there. I cannot imagine Ukraine will tell the Russians their strategy.
