Between 1935 and 1937 Congress passed three "Neutrality Acts" that tried to keep the United States out of the war, by making it illegal for Americans to sell or transport arms, or other war materials to belligerent nations.
Neutrality Act is an act prohibiting the export of arms, ammunition, and implements of war from the United States to foreign nations at war and requiring arms manufacturers in the United States to apply for an export license.
