In 2016, before most people imagined that Donald Trump would become a serious contender for the Presidency, the New Yorker staff writer Adam Gopnik wrote about what he later called the “F-word”: fascism.  He saw Trump’s authoritarian rhetoric not as a new force in America but as a throwback to a specific historical precedent in nineteen-thirties Europe.  In the years since, Trump has called for “terminating” articles of the Constitution, has celebrated the January 6th insurrectionists as political martyrs, and has called his enemies animals, vermin, and “not people,” and demonstrated countless other examples of authoritarian behavior.  In a new essay, Gopnik reviews a book by the historian Timothy W. Ryback, and considers Adolf Hitler’s unlikely ascent in the early nineteen-thirties. He finds alarming analogies with this moment in the U.S.  In both Trump and Hitler, “The allegiance to the fascist leader is purely charismatic,” Gopnik says. In both men, he sees “someone whose power lies in his shamelessness,” and whose prime motivation is a sense of humiliation at the hands of those described as élites. “It wasn’t that the great majority of  Germans were suddenly lit aflame by a nihilist appetite for apocalyptic transformation,” Gopnik notes. “They [were] voting to protect what they perceive as their interest from their enemies. Often those enemies are largely imaginary.”
