Third and fourth terms of the presidency of Franklin D. Roosevelt
On the morning of December 7, 1941, the Japanese struck the U.S. naval base at Pearl Harbor with a surprise attack, knocking out the main American battleship fleet and killing 2,403 American servicemen and civilians. The great majority of scholars have rejected the conspiracy thesis that Roosevelt, or any other high government officials, knew in advance about the Japanese attack on Pearl Harbor. The Japanese had kept their secrets closely guarded, and while senior American officials were aware that war was imminent, they did not expect an attack on Pearl Harbor. Roosevelt had anticipated that the first attack would take place in the Dutch East Indies, Thailand, or the Philippines.
Doolittle Raid
Despite the minimal damage inflicted, American morale, still reeling from the attack on Pearl Harbor and Japan's subsequent territorial gains, soared when news of the raid was released. The Japanese press was told to describe the attack as a cruel, indiscriminate bombing against civilians, women, and children. After the war, the casualty count was 87 dead, 151 serious injuries, and more than 311 minor injuries; children were among those killed, and newspapers asked their parents to share their opinion on how the captured raiders should be treated. For years before the attack on Pearl Harbor, there had been mock air raid drills in every Japanese city, although China's air force was almost nonexistent; this may have been part of the process of keeping warlike emotion at a high pitch.
