Thing is, I don't think the people who run the country believe in all this crap.
Obviously not. But the fact that this is being peddled is a clear indication that the momentum is still building up for the war. They are dreaming though if they think that the resentment will pass. If, by some miracle (Putin resigning in disgrace, for example), a war doesn't happen, you are looking at 15-20 years of future resentment. If Russia actually goes through with the lunacy of invasion, no amount of purges will help. Ukraine will treat Russia in very much the same way that Poland treats Russia. Someone else said it in the thread, and I would tend to agree. The fact that the hostilities are happening is a clear indication that Putin has already lost much of his power.
Russia is a villain. The U.S. is a villain.
Absolutely not. Russia is the villain. US is an impartial observer not participating (yet) in the events, but US is being a prudent observer in stating that it would not do business with a bully (at best) or a madman (at worst). That doesn't make US a villain. It makes US sane.
The current fascist-riddled Ukraine government is a villain.
That's an outrageous lie. The only reason that Russia continue to promote this lie for its internal propaganda is in order to practice the psychological device of "deflection." Russia is a fascist state through and through. It follows all the state doctrines of fascism almost to the letter. And in attempt to avoid such labeling, it accuses another state of fascism. Which is precisely how the deflection pattern works.
