"His primary rules were: 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." -- Psycholological profile of Adolph Hitler, prepared by the US Office of Strategic Services (OSS). Wikipedia entry on the Big Lie.
Michael C. Moynihan asserted in a Tablet Magazine article, "Hitler on the Campaign Trail: Republican and Democratic Politicians Are Reviving A Favorite Nazi Debating Point This Campaign Season" that a common technique in contemporary US politics is to criticize an opponent for [allegedly] using the Big Lie. But it is misleading and incorrect to imply that any such opponent is somehow "similar to" or "analogous to" either Hitler or Goebbels. ("See also" Association fallacy.)
The “big lie” wasn’t a Nazi propaganda “technique,” Moynihan points out. "A little detective work reveals the Big Lie to be a rather big lie. In fact, there is only a single reference to the “big lie” in Hitler’s collected writings and speeches," he writes. "The Big Lie" wasn’t “invented” or “pioneered” by either Hitler or Goebbels. Nor was it the backbone of an anti-Semitic media strategy that precipitated the Holocaust. "If the ubiquitous and industrious fact-checkers bothered to check the claim, they would have gotten a two-for-one: the irony of supposedly truth-seeking politicians perpetuating a historical myth, and the satisfaction in helping rid the Internet of junk history. And perhaps most important, preventing a uniquely evil regime from being banalized by wildly inaccurate historical analogy," he concludes.
