It seems so, Putin's rescheduling his speech to the nation for tomorrow, its a clear sign to me, of he can't give orders as he was used to and he is probably dealing with all the people who doesn't want to continue with the war and wanting bring him down.Putin has no choice but to continue the war, anything less and his career is done. But the Russians have two choices, either leave and save further suffering or be removed by force.
Russia is done in Ukraine. Too many retreats, too many battlefield defeats. Right now Russia is fighting to save Putins career and thats all.
One point to consider here is oligarchs base their richness on enterprises which need specialized workforce, those same workers who are searching right now on Google how to leave the country safely without getting in a plane with no maintenance.
