Answer 1

The primary reason the United States entered World War II was the Japanese attack on Pearl Harbor on December 7, 1941. This surprise military strike led to significant casualties and damage to the U.S. Pacific Fleet and prompted Congress to declare war on Japan the following day, marking the U.S. entry into the conflict.
