When I look at other communist nations, they were invaded, couped, and/or sabotaged at every opportunity, and (forgive me, my history of China is weak) while I’m sure that China faced obstacles from capitalists outside of the country, it somehow rose up to be the power that it is today while the USSR fell, Vietnam and Korea got bombed to hell and back, Cuba was put under crippling sanctions, and surely countless other uprisings got squashed young.
But china didn’t just survive, they thrived. How?
Then China qualified Khruschyov as revisionist and started to degrade relations. How is any of this on Stalin?
Socialism in one country leaves a place for a nation with a socialist developmentalist aim to occupy. China ended up being the one who occupied that space. Socialism in one country is a contribution generally attributed to Stalin, not that I think he had any choice in the matter.
