If it's not on the list, it either wasn't a communist country, or didn't experience a revolution. Thank you for reading.

you missed a bunch but also I would question the "success" in places like Somalia or Angola which never really began the process of building socialism

Afghanistan was not really a revolution

excluding the dprk but including kampuchea is a choice

sure it was. women and minorities were in fact liberated by 1979. the problem was of course revisionism and the nature of the protracted struggle against counterrevolutionaries.

where is all of Eastern Europe? czechslovakia and albania are here and I dont appreciate the insinuation, all of the post-wwii communist governments waged cultural revolution against backwards cultural forces and placed the proletariat in control of the productive forces. of course their were limits and uneven development and eventually a turn toward revisionism but these were genuine grassroots socialist movements that irrevocably changed these nations.

this is a far cry from somalia where nationalists looked toward the imperialist powers for support in their irridentist dreams and then dropped any pretense of socialism once isolated from the OAU.

Maybe on paper and in Kabul but the lack of a mass line or mass interest (the change of government was orchestrated through a coup by the army and intelligentsia and not a vanguard party with worker participation) removes the concept of it being a social revolution with true political consequence

again this is simply a problem of correct politics. I support practically the actions of the PDPA even if I don't support the line of the party that won out in the end. it is possible to separate the two.
