American Isolationism

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.

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.
