I disagree. Ukraine is holding back. If Prigozhin wins, he has already called the Ukraine "special military operation" a mistake. Easy for him to negotiate a peace. Easier for the Russian military commanders on the front to side with Prigozhin if they are not fighting the Ukrainians.
Either Prigozhin wins, or things get really messy. Time enough for the offensive if things get really messy.
If I were the Ukrainians I would regroup and see how this plays out because the biggest threat to Putin has always been his “inner circle”.
If the Chef has convinced his military that Putin and the Russian General Staff intends to kill them or incarcerate them again they will be quite motivated and if that was NOT the perception before it is now because they killed a bunch of them with an artillery strike.
If we believe the media coverage.....
