While it is true that Trump, in his campaign, relied heavily upon American nationalism and you DO make some interesting points in your comparison of Trump to Hitler, you fail utterly to make the comparison historically of pre-WWII Germany and the American landscape today. Germany was decimated financially and in terms of morale after WWI. The people were downtrodden in the extreme. America on the other hand, is one of the most successful economic countries on the planet. Admittedly, WE don't necessarily see it that way, but in truth, Americans are far and away among the wealthiest and best cared for people in the world.
Hitler's rise to power was aided greatly by a German people in dire need of a leader who could give them back some self worth and dignity. Who could help them understand how they'd been so thoroughly trounced in WWI. You have to remember, not only did they lose, but they were widely regarded as the villains. This was a powerful blow on the collective psyche of the country and many of the people had a difficult time facing defeat. They wanted to believe that they'd been betrayed from within by the economic and manufacturing arms of the country who gave out before the fighting men and women. Thus when Hitler came along and turned Germany into the well-oiled manufacturing war machine that it became and further gave the people a likely scapegoat for their earlier failures, the jewish business class and bankers who had ultimately betrayed them in their earlier time of need and truly just before their greatest victory, well it was easy enough to turn ordinary people into head-turning ignorants who could look the other way at the very least.
Now Trump is in a different position. America is less financially down-trodden, less militarily beaten than it is corrupt, scandalized and bloated on it's own corporate scheming. Trump simply took advantage of the common man's growing disgust with how our political system has begun to fail us more and more. By pointing out the "swamp" as he so elegantly called it, he spoke to the masses who are tired of the glad-handing and me-first attitude of our senators and congress leaders. Can he accomplish anything? Perhaps, perhaps not. But the fact that a complete non-politician was elected to our highest office, unseating a career stooge with a gigantic lead in the polls speaks volumes.
True, confounded liberals everywhere are shocked, dismayed and up in arms about Trumps election. But a quiet and overwhelming group of voters is still completely sick of the charade of American politics. And the continuing theatrics performed nightly by our "news professionals" does nothing to help us develop a respect or appreciation for their reporting OR our leadership. There is very little hope at this time for American leadership going forward. I seriously doubt this country will ever find a leader that can begin to unite the people ever again. At this point the intolerance of the press and the public toward our public offices has reached a tipping point that likely can never be reversed. It would do little good to attempt to enforce laws about threatening the president or senators or congress ever again. How could we possibly expect our citizenry to respect our leadership when our own press open mocks them on public television?
The irony is. people particularly liberals, want to blame this on Trump. Truly it's the millennials and their complete lack of self control and respect that have brought about this predicament. They've destroyed their own country.
