No true Scotsman? Really?
There are also never has been a real capitalist country.
There hasn't been a true communist country because it can't be done while keeping people free. What happens to those that don't want to join, I hear you wonder? Maybe ask Russia and China about that. Maybe look up "the chekist"? Or maybe look up "Mass killings under communist regimes" on wikipedia?
All communist countries have been communist countries. They were countries with what communism is in the real world. That theoretic theater play where you call each other comrade is kids playing. Real communism is built with blood.
