>>716962>that significantly delayed (maybe doomed but probably not) the building of world communismAnon, the industrial revolution started just a century before the Soviet Union formed. To transition from primitive communism to slave economies took humanity millenia, to transition from slave economies to feudalism took another couple millenia, to transition from feudalism to capitalism took another millenia. That Marx and Engels dropped their theory at the beginning of capitalism proper and that only half a century afterwards the Soviet Union existed remains one of the biggest outliers in the history of humanity, you wouldn't believe. The Soviet Union is directly responsible for the victories in China, Korea, Vietnam and Cuba, all of which are still ruled by communist parties waiting for their chance to go mask off again.
This also isn't a case like Italian merchant republics trying to survive as islands of capitalism in a world of feudalism, China is the world's biggest economy, and the future climate collapse will be the biggest opportunity at world communism, besides colonizing space and outliving the inefficient capitalist systems.
