The communists supposedly killed thousands if not millions of nobles, well off people, and militant anticommunist. Here is my question. Why didnt they just admit their side was whooped, accept the general amnesty granted after the revolution or civil war, and work to help make the new system work instead of still trying to bring it down?
Why is China forcibly trying to force Hong King conform to communist ideology?
Why did communist Russia try to militarily suppress the Polish freedom movement?
As to Russia, when Stalin took power it was all about dictatorship and personal power. Machiavelli, when in power the first order of business is to keep power.
And popular hatred. I read a book Diary Of A Revolutionist by a Russian Kropotkin. He was a noble who made a name for himself as a scientist. He turned radical. He described the life at the bottom. It was what Marx was taking about, abused proletariat.
People did not have names, they had functions. Fisherman, farmer, wagon driver. A noble had a right of first night. When a peasant got married he could have sex with the woman first.
Kill a peasant and you could buy an indulgence from the church. Not hard to see why the communists hated religion, it was a tool of state to control the lower class.
It wasn't until the late 19th century with the rise of Italy as a nation that the Vatican lost its direct political enforcement power.
Overall there was plenty of cause for the revolution. It was the post revolution that became another tyranny. Orwell's Animal Farm..
THe Stalin NKVD was no different than the Nazi Gestapo and SS. There were Russian atrocities in Poland.
Stalin made a non aggression pact with Hitler in exchange for part of Poland and Finland I recall. You can say Stalin enabled Hitler to invade Poland and start WWII,.
Hiter could nit have invaded Poland if there was a chance of Russia resoinding.
Stalin wanted part of Poland which he claimed was historically Russian. Same old emperislidm under the name of communism. Eastern Europe. East Germany and West Berlin.
You are hard pressed to argue Stalin and Russian communism was not just more traditional imperialism.
