My partner family lived in communist Romania. They almost starved when the communists stole their fields to collectivize them and then they misused them. Not only that but the "securitate" (Romanian KGB) created real fear between everyone. This was the real problem of communist Romania, not the foreign intervention. Eventually people got tired of leaving in a state of terror and they overthrew the government.

There's a Spanish book about Communism and the Spanish civil war. In Spanish is "Dime quien soy" something like "Tell me who I am". It talks a lot about people that really believed in the communist idea but that got killed because of Stalin being a dictator.

Edit: To all of you downvoting me. None of you have addressed the trust issues that the "securitate" created in the Romanian society. Many pro-comunists were killed by Stalin's delusion. I'm not saying that communism is completely evil but Romania was far from a paradise.
