During his imprisonment in 1925, Adolf Hitler came up with his theories for a political movement that placed the Aryan (German) people at the top of a hierarchy of races. This movement, later called the Nazi movement, aimed for Aryan supremacy and a central Aryan government that would eliminate "impure breeds" such as Jews and other races.
Hitler's philosophies mirror the American policies of the 1920's. During this period, America adopted an isolationist policy and had a general popular sentiment that looked down upon immigrants, Catholics, Jews and Blacks (Kennedy et al., 382).
Hitler himself admired America during this period and commended them for their immigration policies and popular sentiment that did not favor people of different races. He specifically noted the "race-based anti-immigration laws and for the subordination of the "inferior" black population." and attributes their success to their efforts at keeping themselves racially pure ("Nazi")
This view, however, did not last as he denounced the United States as "a mongrel nation half Judaised, half Negrified" following America's adoption of greater racial freedom and rights. He believed this would cause the United States' early defeat during the war ("Nazi")
Before the bombing at Pearl Harbor, Nazi groups, while vilified by most, existed in the United States. However, the handful that did demonstrate publicly in the United States melted away in the aftermath of Pearl Harbor.
America, in the face of outright hostility from Germany, did not join the fray after Germany's advances in Europe. This was due to its isolationist policy, and its reluctance to be dragged into the war. Although, they believed the rise of Nazi Germany would do no good to Europe, they did not enter the war until the Bombing at Pearl Harbor (Kennedy, et al., 428). And even then, it was Germany that first declared war on the United States. It however, contributed to the Allied cause by sending supplies and materiel to stem the Nazi threat (Bailin, et al., 758).
At the onset of the German invasions in Europe, America did not commit to providing military assistance to its allies in Europe. While Canada immediately declared war on Germany, America merely changed its state from neutral to preparedness. It immediately worked to expand, but not mobilize, its armed forces. However, it hoped the Allies would win and provided financial and material aid to support their war effort (Kennedy, et al., 426). Germany responded in kind by sinking any ship found delivering supplies to America's beleaguered allies with their dreaded U-boats (Bailin, et al., 758).
At home, the American populace was divided on whether to support direct military intervention - championed by the Isolationists, or to stay away from the war, since America was not directly affected by it . Isolationists insisted that America stay out of the war since it was not obligated to.
Historically, the United States favored staying out of foreign affairs - a policy that dated back to its earliest establishments. This policy was only broken during
