The United States entered World War II primarily due to the Japanese attack on Pearl Harbor on December 7, 1941, which resulted in significant loss of life and damaged the Pacific Fleet. Prior to this, the U.S. had been providing support to Allied nations through programs like Lend-Lease but had maintained a policy of neutrality. The attack galvanized public opinion and led Congress to declare war on Japan the following day. Subsequently, Germany and Italy declared war on the U.S., fully committing the nation to the conflict.
