At the onset of World War II, the United States officially pursued a policy of neutrality and non-involvement in the conflict. This policy was officially stated in the Neutrality Acts of the 1930s, which aimed to prevent the United States from being drawn into another devastating world war. The Neutrality Acts prohibited the sale of arms to warring nations and restricted American citizens from traveling on belligerent vessels. Despite this policy of neutrality, the United States did provide aid to the Allied powers, particularly the United Kingdom, through programs such as Lend-Lease. However, it was not until the attack on Pearl Harbor in December 1941 that the United States officially entered the war.
