Following the attack on Pearl Harbor on December 7, 1941, everyday Americans were shocked and outraged, and public sentiment quickly shifted towards supporting military action in response. The U.S. government declared war on Japan the following day and mobilized resources for a full-scale military effort. Citizens across the country volunteered for military service, bought war bonds, and supported the war effort in various ways, such as rationing food and supplies. The attack on Pearl Harbor served as a unifying moment for the nation, galvanizing support for the war and shaping a new sense of national identity and purpose.
