I never said anything about Cuba specifically. I made a general remark that an analysis of whether a country is socialist or not has to concern itself with what is the primary mode of production. I also wanted to bring in historical materialism because you seemed to talk about Marx without (seemingly) understanding this very important part of his contributions.
To be clear, my position was, and still is, that I find your analysis faulty, regardless of what I think would be the right conclusion on Cuba being communist.
