Why did many Americans support isolationism when world war 2 began?

Many Americans supported isolationism at the onset of World War II due to the traumatic experiences of World War I, which left a deep reluctance to engage in foreign conflicts. The Great Depression also contributed to this sentiment, as citizens prioritized domestic recovery over international involvement. Additionally, there was a strong belief in the idea that the United States should focus on its own interests and avoid entanglement in European affairs. This isolationist stance was reinforced by the prevailing pacifist attitudes and a desire to maintain peace at all costs.
