How do Totalitarian regimens use propaganda?

The comprehensive and detailed control of all ideas, beliefs, and statements is one of the most problematic features of totalitarian regimes. Several theories of totalitarian "ideology" have been presented to explain why political, philosophical, artistic, scientific, and historical ideas must conform to what the leadership considers "correct.". totalitarian leadership approaches ideas with the purpose of creating the maximum insecurity among the people it controls. The only exceptions to this generalization occur when the leadership wishes to realize certain short-term goals, like increasing production or stimulating patriotism.
