Tuesday marks the 80th anniversary of the Japanese attack on Pearl Harbor on Dec. 7, 1941, killing some 2,400 American servicemen and leading the U.S. to enter World War II. And 80 years later, myths and misunderstandings persist about what President Franklin Roosevelt called “a day that will live in infamy.” “The attack on Pearl Harbor was a crime, a military attack that took place without a declaration of war,” says Rob Citino, senior historian at the National World War II Museum.
