On top of all the non-sense the system of the Soviets had. Which is why China is, well they state authoritarian but it's more totalitarian.
China is semi-marxist with a capitalist system of course it's not the same as America rather it maintains itself and advances. I guess the jews learned the Soviet Union was incapable of sustaining itself. Even with all the companies being bought out and brought to the Soviet Union.
You can make the argument that Hitler destroyed the USSR in the 40s. Despite losing the War, he dealt such a huge blow to the Soviets they to this day suffer from it.
There is a book whereby paraphrasing it in one sentence. "The second the Russian problem came to the attention of the Germans in 1940 due to issues in Romania. The second operation Barbarossa started, the Soviet Union was defeated 50 years later."
Although of course just because the Soviets advanced and went on and on doesn't mean this to be taken 100% outright rather passively the system was just decked from so many angles eventually without proper fixing it broke down. The Soviets were so obsessed with their plan to exterminate Amalek in Europe and have a "Red Alert scenario" like in Command and Conquer Red Alert, Hell march unto Europe. That they lost site of the bigger picture. Sure Soviet Union is responsible for all the things occurring due to the Comiturn(Communist International) but the Soviets themselves were long defeated.
As much as the Capitalist system of America is terrible unlike the C.C.(Controlled Capitalism) or R.C.(Regulated Capitalism) as I prefer calling it. By the Germans with a combination of German Socialism and Nationalism and needing half the World's nations to beat it down into a rothschild central bank. The funny part is Capitalism even the American kosher Joseph Smith kiked up non-sense has been molded by American thinkers and organizations that have laws and regulations which makes it kinda just barely fight off Sovietized nations.
So just because America barely scraped by it isn't that good just good enough not to collapse to the Soviets. Plus the Gods helped America cause they realized the next nation on the chopping block is America. In other words the battle went from Germany being the main striking force to America.
