U.S. pro-Nazi movements such as the Friends of the New Germany and the German-American Bund played no role in Hitler's plans for the country, and received no financial or verbal support from Germany after 1935.[88] However, certain Native American advocate groups, such as the fascist-leaning American Indian Federation, were to be used to undermine the Roosevelt administration from within by means of propaganda.[89][90] Fictitious reports about Berlin declaring the Sioux as Aryans were circulated by the German-American Bund with the aim of increasing tensions between Native Americans and the Government of the United States, impelling Native Americans to resist being drafted or registered by the Bureau of Indian Affairs; such rumours were reported by John Collier, commissioner of Indian Affairs, to the Congress as true, thus not merely spreading them further but also legitimating them in the eyes of many.[91][92] As a boy, Hitler had been an enthusiastic reader of Karl May westerns[6] and he told Albert Speer that he still turned to them for inspiration as an adult when he was in a tight spot.[93]
