Stalin didn’t like idealist portrayals of himself; yet I see the term CoP associated with him. (In Wikipedia and HoI4 (Soviet Union focus tree) for example.)
I don’t see that term around Mao Zedong, Fidel Castro, and ironically around the DPRK; but they also are demonized as evil dictators that force the people to worship them.
Krushchev was so salty that Stalin was so popular that the only way he could cancel him was by claiming he forced people to like him and by gaslighting the world into believing he was an egoistical despot; all after he was dead, of course.
