In some countries the dictator is seen as a living god, and the people feel it is their god given duty to just obey the leader since he always knows best. This seems to describe Stalinist Russia, Maoist China, Japan under the Emperor, North Korea under Kim Il Sung and probably Germany under Hitler to name a few.
However after the dictator falls, how do you go about bringing the end to the cult of personality? The Kim dynasty in Korea will eventually end, so what is going to happen to de-Kim the country since 1/3 of education is designed to preach loyalty to Kim, and statues and pictures of Kim are everywhere? After Stalin died I think Kruschev waited a year, then gave a report on all the atrocities Stalin committed while tearing down the statutes and monuments to Stalin. Wouldn’t tearing down the statues and monuments to the leader willy nilly cause massive revolt and mass suicide in a cult of personality dictatorship? If flushing the Koran down the toilet can lead to violent revolts then how do you end a cult of personality dictatorship?
