Communism is alive and well

I have friends who think communism died when the Soviet empire collapsed and Eastern Europe freed itself. China's move away from its failed version of communism was followed by other dictatorships, like Vietnam. Now Cuba wants to adopt capitalism to protect the ill gotten perks of the party oligarchs. 

But communists seem to insist on rebuilding the past, and will continue wrecking nations like they are doing to Venezuela at this time. This is why I tell my friends communism will always attract followers, and will always remain a threat.
