We must have different definitions of “wrong”. The Nazis exploited the feeling within Germany of betrayal, pushing the notion that Germans were exceptional and not to blame for their troubles. Like Hitler, Trump never accepted responsibility for any failures; it was always somebody else’s fault. The lies and propaganda are of the same kind. Attacking and subverting democratic processes; exactly the same.
Far right nationalism underlies both regimes. I can’t think of any American President coming as close to Trump in the similarities of doctrine and method to those employed by the Nazis.
The big difference is that the Nazis were more competent in administration.
