Pearl Harbor

The man who declared the attack on Pearl Harbor "a date which will live in infamy" might actually have had prior knowledge of it. Franklin D. Roosevelt is remembered as a saintly figure who tried to keep the U.S. out of WWII until the Japanese surprise attack killed over 2,400 Americans and wounded 1,200-plus others. But evidence suggests the FDR had been searching for a casus belli for months as a reason to declare war on Hitler.
