What event dragged the US into World War 2?

The event that dragged the United States into World War II was the Japanese attack on Pearl Harbor on December 7, 1941. This surprise military strike targeted the U.S. naval base in Hawaii, leading to significant loss of life and damage to the Pacific Fleet. In response to the attack, President Franklin D. Roosevelt declared war on Japan the following day, marking the official entry of the U.S. into the conflict.
