What role did the policies of isolationism and neutrality play in us decisions about ww1?

The policies of isolationism and neutrality significantly influenced U.S. decisions regarding World War I, as many Americans believed the country should avoid entanglement in foreign conflicts. Initially, these policies led the U.S. government to maintain a stance of non-involvement, focusing on domestic issues and trade. However, as events like unrestricted submarine warfare and the Zimmermann Telegram threatened American interests, public sentiment shifted toward intervention, ultimately leading to the U.S. entering the war in 1917. This transition marked a departure from isolationism, reflecting the complexities of global politics and national security.
