Isolationism is a foreign policy approach where a nation avoids involvement in international alliances, conflicts, or affairs. This strategy emphasizes self-sufficiency and focuses on domestic issues rather than engaging in external politics or military actions. During the years leading up to global conflicts, especially World War II, isolationism influenced the actions and attitudes of various countries, particularly in how they responded to threats from aggressive regimes.

Review Questions
How did isolationism shape U.S. foreign policy during the interwar period?
Isolationism significantly shaped U.S. foreign policy during the interwar period by promoting a reluctance to engage in international conflicts and alliances. The public sentiment against involvement in foreign wars led Congress to pass the Neutrality Acts, which restricted arms sales and financial assistance to nations at war. This policy was rooted in the desire to focus on domestic issues and avoid repeating the horrors of World War I, ultimately limiting the U.S.'s ability to respond effectively to growing global threats.
Evaluate how isolationism contributed to the rise of aggressive regimes in Europe during the 1930s.
Isolationism allowed aggressive regimes like Nazi Germany and Fascist Italy to expand their influence unchecked. As countries like the U.S. adopted non-interventionist policies, it emboldened these regimes to pursue expansionist goals without fear of immediate repercussions from major powers. The lack of collective action against these aggressors meant that their actions went largely unchallenged, leading to increased tensions that eventually escalated into World War II.
Assess the implications of isolationism on America's role in World War II following Pearl Harbor.
The implications of isolationism on America's role in World War II were profound after the attack on Pearl Harbor. The event shattered isolationist sentiment overnight, galvanizing public support for entering the war and leading to a complete shift in foreign policy. America's entry into World War II marked its transition from a nation focused on self-imposed separation from global affairs to an active participant in international coalitions aimed at defeating totalitarian regimes, fundamentally changing its position on the world stage.
