I don't pretend to be an expert on Russia, far from it. The more I learn the more I realize how little I know. I do know this, we have never understood the Russian mindset and most of us never will. This video from Vertigo Politix, The Soviet Genocide of Russia's Old Believer Christians, explores some of the worldview of the Russian people and why they don't trust the West, especially a certain ethnic group.
You will probably have to watch this on Youtube as it is age-restricted, which is fair because it has some disturbing imagery.
The Russian view of Russia and of the West is diametrically opposed to how we see it and in our Western chauvinism we of course assume they are completely wrong. There is a reason Russians celebrate the achievements of the Soviet Union in World War II even though their "victory" secured the tyranny of Communism for half a century over Russia and Eastern Europe. Our failure to understand them means we also underestimate them and that can be a fatal error on our part. Russia will do more and go father to preserve Russia than the West will. I don't think there is a limit to that willingness. They have survived unimaginable suffering before and they can do so again. Can we?
