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.
Battle of Wake Island
On 8 December, just hours after the attack on Pearl Harbor (Wake being on the opposite side of the International Date Line), 36 Japanese Mitsubishi G3M3 medium bombers flown from bases on the Marshall Islands attacked Wake Island, destroying eight of the 12 F4F-3 Wildcats on the ground. The remaining four Wildcats were in the air patrolling, but because of poor visibility, failed to see the attacking Japanese bombers. These Wildcats shot down two bombers on the following day. All of the Marine garrison's defensive emplacements were left intact by the raid, which primarily targeted the aircraft. Of the 55 Marine aviation personnel, 23 were killed and 11 were wounded.
