Before entering World War II, the U.S. practiced isolationism by avoiding entanglement in European conflicts and focusing on domestic issues. The Neutrality Acts of the 1930s were designed to prevent American involvement in foreign wars by restricting arms sales and loans to warring nations. Public sentiment largely favored staying out of international affairs, influenced by the devastation of World War I. It wasn't until the attack on Pearl Harbor in December 1941 that isolationism shifted dramatically, leading to active U.S. participation in the war.
The U.S. had several compelling reasons for entering World War I, as outlined in Wilson's 1917 speech. These included the need to protect democracy and ensure global stability, especially in response to German aggression and unrestricted submarine warfare that threatened American lives and commerce. Additionally, the U.S. sought to uphold international norms and promote a peace that could prevent future conflicts. Overall, these motivations reflect a broader commitment to global leadership and the defense of democratic values.
