BW got it right. There are no and have been no truly communist countries. They always exist as a dictatorship or an oligarchy. The leader/leaders maintain their grip on power by incarcerating or killing any opposition. (Che's Job, kill the opposition for Fidel) ?Both Che' and Mengele were MDs. Both worked for the tyrant in control of their respective countries, and both were essentially assassins on a major scale.
The only form of civil relationship that approached the Communist Ideal was practiced by some of our Native American tribes. We fixed that in a hurry didn't we?
Btw Lupo. The labels don't mean much, Facist, Communist, Imperialist, Colonialist. All just labels useful for the name callers that like to label everything to fit their convoluted view of the world.
