As being, in both cases "Charismatic Leaders" of course the "Shoe fits". Hitler, in the governmental sense, did a very GOOD JOB of creating a German infrastructure, much of which is still in place, and functioning nicely.
Hitler wanted to EXPAND, however, and he had this "thing" about Jews.
In THAT respect, the two don't compare well at all. Trump wants to BRING BACK the U.S. Manufacturing infrastructure that we've largely given away, and he's not interested in conquering Canada or Mexico.
