American Isolationism refers to the foreign policy approach taken by the United States in the years following World War I, characterized by a reluctance to engage in international conflicts and alliances. This stance emerged from a desire to avoid the mistakes of past entanglements, particularly those that led to the devastation of WWI, and was marked by a focus on domestic issues rather than global affairs.

Review Questions
How did American Isolationism shape U.S. foreign policy decisions during the interwar period?
American Isolationism significantly influenced U.S. foreign policy during the interwar period by leading to a reluctance to intervene in European conflicts and an emphasis on domestic matters. The refusal to join the League of Nations exemplified this approach, as Americans believed that involvement in international organizations could entangle them in unwanted wars. Additionally, the Neutrality Acts reflected a legal framework aimed at ensuring that America remained uninvolved in global conflicts.
Analyze the effects of the Great Depression on American Isolationism and public opinion towards foreign engagement.
The Great Depression reinforced American Isolationism as economic struggles prompted citizens and policymakers to prioritize domestic recovery over foreign affairs. The crisis led to widespread disillusionment with international engagement, as many viewed previous involvements—like WWI—as costly mistakes. Consequently, public opinion leaned heavily towards non-interventionist policies, making it difficult for leaders advocating for involvement to gain traction.
Evaluate how events leading up to World War II challenged American Isolationism and contributed to a shift in policy.
Events leading up to World War II, particularly the aggressive expansion of totalitarian regimes in Europe and Asia, increasingly challenged American Isolationism. As conflicts intensified and nations like Germany and Japan posed significant threats, isolationist sentiment began to wane. Key incidents, including aggressive military actions by these nations and humanitarian crises resulting from their conquests, prompted a reevaluation of isolationist policies, culminating in legislative measures like the Lend-Lease Act which marked a pivotal shift toward greater involvement before formally entering WWII.
