How did Hitler's views compare with American views in the same time period? (Specifically, WW2).

Hitler and his henchmen victimized an entire continent and exterminated millions in his quest for a co-called "Master Race." But the concept of a white, blond-haired, blue-eyed master Nordic race didn't originate with Hitler. The idea was created in the United States, and cultivated in California, decades before Hitler came to power. California eugenicists played an important, although little known, role in the American eugenics movement's campaign for ethnic cleansing.
