Puting aside Russia as the stiking point for a moment...
"The following are inarguable, Marxist-Leninist Communist Totalitarian states:
And in the category of Communist states who allow a bit of "capitalism" ala the NEP:
* The PRC (Red China)
In the category of "New Age" crypto-Marxist states:
* Venezuela (rapidly heading toward full-fledged Comm. Rev.)
* South Africa
* And as of their most recent election, Spain
Oh, and then there are all the still active "old hippie radical" type Communists who make up certain Western factions.
Communism is still very much alive."
Belarus? They have a petty dictator but they have free enterprise.
Latvia? Best not tell the Latvians, they'd be in a real surprise.
Burma (Mymar) is a militacracy, just like Pakistan. Sorry, not communist. They overthrew the socialists.
The only true communist states are: N.Korea, Vietnam, Laos, Zimbabwe (more or less), Cuba. Venezula might become one but I doubt it. It will go into civil war.
