How so?
Communism, as a state, requires rules. By that virtue, it’s not anarchy.
Communism as the utopian ideal I suppose could be considered anarchy, but in reality that would never happen, so IMO not really worth discussing.
The two are often conflated, but this fact is fundamental to communist philosophy, economics, and literature.
The USSR was the Union of Soviet Socialist Republics, not "Communist Republics"
As a term, communist state is used by Western historians, political scientists, and media to refer to these countries. However, these states do not describe themselves as communist nor do they claim to have achieved communism — they refer to themselves as socialist states that are in the process of constructing socialism and progressing toward a communist society.[1]
