“The real reason the Soviet Union failed was atheism, not socialism.”
Wow... just wow.
If your theory were correct, then simply changing the economic system would result in a revitalized Soviet Union. Instead you have a nation with rampant alcholism and out of wedlock childbirths, massive poverty, and a few corrupt mega-wealthy people.
It’s been more than 15 years since the end of the Soviet Union, yet Russia is going nowhere, unlike Eastern European countries with stronger Christian roots.
