Today is Pearl Harbor Remembrance Day. On Dec. 7, 1941, 2,400 service members and civilians lost their lives in the two-hour air raid by Japanese forces on the U.S. naval base in Hawaii.
The sneak attack shook America's confidence and pulled the country into World War II. Congress designated Dec. 7 as National Pearl Harbor Remembrance Day in 1994.
This Sunday marks 84 years since the attack on Pearl Harbor.
