also the american eugenics movement which started in the late 1800′s was a huge inspiration for Hitler, and was even where the idea of blonde hair blue eyed superiority came from, and the idea of a “gas chamber” to take care of “undesirables”. In the early part of the third reich, the american eugenics movement saw it as the logical conclusion of their ““research”” and republished lots and lots of nazi propaganda 

Hitler praised American immigration restrictions in Mein Kampf. When the nazis wrote the notorious Nuremberg Laws, the centerpiece anti-Jewish legislation of the Nazi regime, they specifically modelled them after the Jim Crow Laws, the Citizenship Law and the Blood Law of the United States.
