The establishment of the Third Reich influenced events in American history by starting a chain of events which culminated in war between Germany and the United States. The complete destruction of democracy, the persecution of Jews, the war on religion, the cruelty and barbarism of the Nazis, and especially the plans of Germany and her allies, Italy and Japan, for world conquest caused great indignation in this country and brought on fear of another world war.

The Neutrality Acts of 1935 and 1936 prohibited trade with any belligerents or loans to them. In 1937, the President was empowered to declare an arms embargo in wars between nations at his discretion.
