It's not just that, I think. One point I hadn't fully realised until I started reading Timothy Snyder's books on the subject, particularly Black Earth, quite how much Hitler, and the Germans generally, saw the USA as a model for their colonial project. I knew that Hitler and the Nazis admired the laws in some US states on racial segregation and eugenics (particularly compulsory sterilisation of those deemed unfit to breed) to the extent they modelled the Nuremberg Laws on them, but it went much further than that:
(from Black Earth, chapter 1)
That attitude really informed Nazi planning and policy towards the East -- the general idea was that Germany needed the vast potential resources, agricultural and industrial, offered by Poland, Ukraine and European Russia and which were going unexploited by the racially inferior "Slavic" inhabitants, who would be driven off their land and allowed to starve while these territories were claimed and made prosperous by sturdy German pioneers, assisted by their families and slaves drawn from the German-administered reservations (such as the "General Government", as the remains of what was formerly Poland were called) in which the surviving "Slavs" (formerly Poles, Ukrainians, Russians, Lithuanians and Belarusians) languished, as did their native American counterparts across the Atlantic.
As with most other social and intellectual movements, the C18th European enlightenment had a good side and a bad side, and both of those developed in their various ways in the USA as much as they did in Europe. Beebo has already pointed out to me the way that, historically, in large tracts of the US the protection of law and the constitution has never extended much further than the local powers that be allow it to (and certainly not to Native Americans, particularly where the land they happen to be occupying at the time takes the fancy of white Americans), and this is just another point of congruence between the C20th National Socialists and the C19th American politicians, pioneers and soldiers they saw as their precursors.
I don't know if Hitler's views on Andrew Jackson are known, but I'm pretty sure he would have been as great a fan of that gentleman as is the current incumbent of the Oval Office. Certainly many Nazi economic prescriptions could be summarised as "Go East, young man!".
