I think the Russian populaiton is still largely supporting Putin and eating his propaganda on bread every morning and evening from state media channels.
Some of them who are fed up cannot do anything about it as they can face extremely harsh punishments.
The elites may be sick of it, they lost a lot of ‘business’ since the start of the military operation, and from time to time another one bites the dust from an open window high up on a building.
And there are factions within Russia that fight one another and yet they are somehow all in support of Putin.
