America entered World War II primarily due to the Japanese attack on Pearl Harbor on December 7, 1941, which killed over 2,400 Americans and galvanized public opinion in favor of entering the conflict. 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 prompted Congress to declare war on Japan the following day, and shortly after, Germany and Italy declared war on the United States, fully involving America in the global conflict.
