“Never allow the public to cool off; never admit a fault or wrong; never concede that there may be some good in your enemy; never leave room for alternatives; never accept blame; concentrate on one enemy at a time and blame him for everything that goes wrong; people will believe a big lie sooner than a little one; and if you repeat it frequently enough people will sooner or later believe it.”

I know what you’re thinking. You’re thinking, “Oh, it’s another assessment of Donald Tump and what he does to hold onto his power.”

It is totally reasonable that you would think that, but you would be wrong. This quote is from the USOSS (predecessor to the CIA and NSA) assessment of Adolph Hitler during his rise to power.
