They own and rule the dictatorship. It's a dictatorship of the proletariat, wherein anyone can become a party member and participate. The US has a dictatorship of capital. How's that working out again having a dozen billionaires writing your laws and controlling the entire executive branch?
No it's a dictatorship by a small group that the rest of them are not in. It's a dictatorship that demands the common people surrender all beliefs not sanctioned by the state, that demolishes holy sites, a dictatorship that forces minorities into labor camps. It's a dictatorship that commits hostile takeovers of neighboring nations and allies itself with multiple other dictatorships.
