Isolationism: A significant portion of the population, inspired by the devastation caused by World War I, wanted to avoid direct involvement in foreign affairs. Isolationist sentiment was expressed in policies like the Neutrality Acts, which aimed to prevent the U.S. from being drawn into conflicts.
Interventionism: On the other hand, there was also a growing movement advocating for intervention, especially against the fascist powers of Europe and Japan. This group favored providing support (like military aid) to Allied nations engaged in fighting the aggressors.
Anti-war Sentiment: A pacifist movement within the U.S. advocated against any form of military involvement, citing the horrors of mechanized warfare witnessed in recent global conflicts.
European Theater Focus: The attention of many policymakers and the general public was initially more centered on developments in the European theater, where the war between Germany and its adversaries raged on.
Economic Impact: The Depression's lingering effects influenced national priorities, with some focusing on domestic issues and reconstruction.
War Support Groups: Organizations like the "Aid for Britain" campaign emerged to provide non-military support to Britain and its allies.
Overall, the mood and atmosphere in the U.S. were characterized by a mix of isolationism, interventionist debates, concerns over the economy, and a sense of uncertainty regarding its role in international conflicts.
