Leaving aside the faults of the current regime and concetrating on South Africa's apartheid era: 
 *Totalitarianism: No black votes. Liberal party disbanded when inter-racial parties banned. Communist party banned. ANC, PAC and other parties banned. End Conscription Campaign and many other bodies banned. Newspapers banned, other newspapers closely monitored with news censored. "Immoral" and many political books banned. Many people "banned" from publication or from association (house arrest).  BOSS and "security police".  Detention without trial as long as 180 days renewable by a magistrate.  Other than that(!) opposition by moderate White parties tolerated. 
 *Corporatistic economics: Telecom, railways, steel, electricity: All state owned and either de facto or legal monopolies. Other examples existed.  Operated effectively as arms of the state. 
 *Anti-communism.  Fanatical!  The minister of Justice could just name someone a communist and they were effectively banned.  Communist party banned for decades. 
 *Militarism:  Two years national service by White males followed by 2 month tours for 10 years.  Repeated military excursions into neighbouring countries.  Long protracted and "secret" (not reported in SA) invasion of Angola.  Military budget higher proportion of GNP than most other countries.  Security Council - essentially a committee of the State President, Law & Justice, Police and Defence ministers together with military leaders - ran the country for years. 
 *Radicalism.  Wasn't tolerated!  Which is pretty radical, if you ask me.  Strict conformity to party line.  "If you not with us you're against us" logic.  
 *The 20% or less Whites had all effective power.  Afrikaners, 60% of 20%, dominated those.  So, a racial and language elite. 
 Doesn't any of that count?
