The attack on Pearl Harbor on December 7, 1941, served as a pivotal moment in U.S. history, uniting the nation and leading to its entry into World War II. Despite the surprise assault causing significant destruction and loss of life, including nearly 2,500 Americans killed and over 300 aircraft destroyed, the U.S. Pacific Fleet's aircraft carriers were unscathed, setting the stage for future military operations. The aftermath of the attack also led to heightened anti-Japanese sentiment, resulting in the internment of Japanese Americans and changing public perception of those of Japanese descent.
