Basically the waiting game;
Scenario A:
Russia topples itself, eurosceptic via old government to europhile via new government.
-- Not sure how long this can be kept before old government stooges take the government again.
Scenario B:
Russia bunkers down, Cold War 2.0, basically uninvadable as Russia government got its act together. With Russian population support for Supreme Soviet State 2.0 by any means necessary.
-- Most Russians want the USSR back do to propaganda forced fed to them. This would last a long time.
However, a swift invasion into Russia with a swift exit would send the message: "You are the baddies"
I don't think it's most, but there sure are a lot of them. Problem is, most of these generally much older Russians don't know anything else. And it goes back generations, through the Czarist period. Russian people have really only known subjugation and autocracy. It's probably the longest-running despotic country in the world.
There are, of course, a very significant number of pro-democracy, young, progressive people that want to see Putin and his mafia cretins gone, and Russia joining a free and prosperous world. A lot of them consider themselves part of Europe, and they should be. It's hard to see this because their primary platforms of information get arrested and silenced, or simply murdered.
They can't speak or gather freely, which is the primary reason you wrongfully think that they aren't a significant, future version of Russia.
