That led to massive backlash from Heritage’s allies in the conservative movement, from Republican officials, and even within Heritage itself — with one staffer telling The Hill that Fuentes “is not someone with ideas worthy of debate.”

Hitler was no less of an antisemite, of course, and his identification of Jews as the chief culprit for everything wrong with Germany led almost inexorably to the conclusion that exterminating them was justified and necessary. But Hitler was politically savvy and capable of adjusting his pitch to fit particular moments. Mainstream publications sometimes foolishly assumed that his antisemitism was a bit of empty rhetoric designed to get votes, or saw him as a clown and failed to perceive the nature of the danger he presented. The lesson I take from this is that we must be more careful in our own time. When we see a neo-Nazi gathering steam, we must expose them and prevent them from taking power. We must be constantly vigilant, because the original Nazis were clever. They fashioned themselves into a mainstream political party, and they bided their time. They waited for just the right moment, a time of national despair and chaos, and then took advantage of it to unleash their diabolical program. Never again—one hopes.

The “Jewish Power” quote is one of Fuentes’ milder remarks. Fuentes is open about his love of Hitler. He has called Hitler “cool” and “awesome,” describing himself as “just like Hitler.” He gives the Sieg Heil salute. He has commented “They compare Putin to Hitler like it’s a bad thing.” Polish people have “the bad habit of hating Hitler all the time,” he says. Asked directly whether Hitler was bad, Fuentes refused to respond directly, saying that if Hitler was “bad,” Churchill and Roosevelt are also “bad.” (Some of the most popular YouTube comments: “I love Nick’s response. Not letting others manipulate his thoughts and words.” “Dude has guts.” “People act like Hitler opposed that group for no reason whatsoever.” “Nick makes such a good point. There's no other historical world leader they would ask this question about.”)
