For context: I'm Estonian. Our nation has a great deal of history with Russian imperialism, under both tsarist and soviet rules. Even Putin has threatened us before. So clearly I'm not a supporter of the Russian regime or their imperialistic ambitions. However, I'm going to present an unpopular opinion.
The balkanization of Russia, if it were to happen, would not be beneficial in the long run. At least not for the people at large.
Yes, the big western cities would be a lot more liberal and open to democracy than the vast countryside. However, we need to consider the fact that different Russian oblasts have VAST differences in economic power. The big cities will thrive on their own, sure, but their tax money would then no longer be used to help people in the more remote regions. Not that these regions are getting a lot of attention now, but at least under a different regime for the current Russian nation as it is, it'd be possible to improve infrastructure, education, industry, etc. for towns in remote oblasts.
And leaving those people farther and farther behind, will cause new unrests. And definitely there would be military dictatorships who promise better lives, etc.
Therefore, a division of Russia into small states might actually cause more issues in the long run. Not that I'm a fan of it staying intact either.
It's a choice between two evils of unknown magnitude, the only good thing is that none of us are the ones making that choice so we don't have to live with it on our consciences.
