A rather parochial assessment of things, since you are defining what is Communism, and not the regimes implied.
The USSR stood for Union of Soviet Socialist Republics.....
Poland was the People's Socialist Republic, was a true democratic republic [with one party like the US in 1776] but you would be "disappeared" for hanging with the wrong crowd or imprisoned for trading in American blue jeans. Over 20,000 political prisoners...that sir, is socialism.
Socialism sooner of later must become all encompassing, totalitarian as each new measure requires deeper and deeper involvement in people's everyday lives. The left in America glorifies socialism while waging war with it 90 miles off its coast; Cuba is no more Communist than Belgium.
The myths and memes live on through ignorance. The US populace spews goo fed to them by propagandists but have never cracked a book on political science, never been to any of the countries on which they pass judgement and sure as hell aren't ever going to listen to a different message. Without ever having set foot in Cuba or any other Socialist country you buy into the lie: Socialism = good. Communism = bad, when they are one in the same.
What you might call socialism are governments like Canada who have a capitalist friendly government which has adopted some socialist practices in an efficient way.
