Russia has spent the last 500 years bouncing around between malevolent autocrats. Hell, Kruschev was one of the more “sane” heads of state for which he was rewarded by being forced into “retirement.”
The only way there will be a regime change is if the current regime is burned to the ground and then there’s no guarantee that what comes next will be better. I’m not even sure what will happen when Putin finally kicks the bucket which will likely open a massive power vacuum.
There’s a need for change but it would be naive to think that the path to it would be painless. It won’t.
Hey now. Every village has its idiots. We just happen to have a lot of them.
