Excuse me for a one-off useless comment, but a Communist country never existed. USSR was not communist.

Communism is being described as "A communist society would have no governments, countries, or class divisions."[1] Hence, no rulers. Communism in its essence is a form of Anarchist society.

For most idealistic -isms, I doubt any implementation could exist that would satisfy the -ism's true believers (particularly since those implementations would have flaws that would need to be disclaimed).
