That doesn't make sense. The West has been ruled by fanatical internationalists since WWII also and that didn't stop them.

West only declared internationalism, never really practicised it. Combination of rotten Western aristocracy with its "burden of white man" with Jewish financial and cultural elite could be for anything, but internationalism.

Soviets was Russians who never had this "burden of white man" with system that didn't depend on bankers.

What percentage of children even go to Church?

If you mean every Sunday services - very few, of course. But religious holidays and overall Orthodox heritage - is very noticeable. Just a day ago - a lot of children with parents in churches and streets, everybody cheer each other and so on. Even not religious families baptize their children and celebrate Orthodox holidays. It is accounted as a matter of course, really. And most people at least trying to follow common Orthodox faith principles. Standard "thank you" in Russian is literally shortcut for "God Save you" - "спасибо" = "Спаси Бог" from Orthodoxy.

However, Orthodox Christianity here is not forced on people, may be this is one of the reasons it is popular here. :)

Well, we also have "Old New Year" holiday.... Don't even ask. :)

I knew the Red Army helped get the narrative going. I remember reading that they came up with the insane initial figures of the victims in Auschwitz but looks like they exported their propaganda to the west.

Red Army didn't care much about specific etnicities. Figures of USSR citizens found in German concentration and labour camps was huge, because the war was huge, with large areas occupied by Germans who need workforce, but that does not mean that jews was the largest group. In reality, Jews was the first who flee en masse to the East of USSR when the war started, so not many left on occupied territories. Most civilian losses was Russians by absolute value and Belorussians by rate. When Germans got that they failed (mid-1942), they began to destroy everything and kill population in areas they couldn't hold. They also tried to move anything of value and those who could be a workforce to the Reich while retreating. But there was no much jews, because most jews flee long before.

Then, I suppose, jewish propagandists used that huge figures of displaced and killed people in their chutzpa.

It wasn't hard for jews to convince West this figures are their only, because West just don't have any clue about the scale of USSR participation in WWII. They don't even know who really won that war and how insignificant was USA/UK/France role in it. :)
