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.
Consequences of the attack on Pearl Harbor
However, in spite of the perceived inevitability of the war by many Japanese, many also believe the Pearl Harbor attack, although a tactical victory, was actually part of a seriously flawed strategy for engaging in war with the U.S. As one columnist wrote, "The Pearl Harbor attack was a brilliant tactic, but part of a strategy based on the belief that a spirit as firm as iron and as beautiful as cherry blossoms could overcome the materially wealthy United States. That strategy was flawed, and Japan's total defeat would follow."
In 1991, the Japanese Foreign Ministry released a statement saying Japan had intended to make a formal declaration of war to the United States at 1 p.m. Washington time, 25 minutes before the attack at Pearl Harbor was scheduled to begin. This officially acknowledged something that had been publicly known for years. Diplomatic communications had been coordinated well in advance with the attack, but had failed delivery at the intended time. It appears the Japanese government was referring to the "14-part message", which did not actually break off negotiations, let alone declare war, but did officially raise the possibility of a break in relations. However, because of various delays, the Japanese ambassador was unable to deliver this message until well after the attack had begun.
