Ok, let me spell this out…

1. Marx and Engels created the concept of Communism. They carefully defined it.

2. No nation in the history of the world has come close to meeting the criteria/definition of Communism.

3. You cannot pick a Communist nation because not one has ever existed. Literally. By definition.

A dictator who lies about their dictatorship is still a dictator, just as a wolf in sheep’s clothing is still a wolf.
