The document discusses U.S. isolationism after World War I and policies leading up to American entry into World War II. It provides statistics on U.S. casualties and costs from WWI as well as outlines the Neutrality Acts of the late 1930s which aimed to keep America out of future European wars by limiting trade. However, the Lend-Lease Act of 1941 ended U.S. neutrality by allowing America to supply allies like Britain with war materials important to the defense of the U.S. against the Axis powers.
