On December 7, 1941, at 7:53 am, Japan launched a surprise attack against the American fleet anchored peacefully in the base at Pearl Harbor. But, far from being intimidated and seeking peace with Tokyo, as the Japanese leaders hoped, the Americans united around their President Franklin Roosevelt and went to war. The conflict is becoming truly global. Yet Pearl Harbor has not revealed all of its mysteries. That the Japanese had succeeded in an attack of such magnitude against the world's leading power seems foolish. Some even suspect the Americans of having let it go. The attack on Pearl Harbor is a military operation that will be a major turning point in the history of World War II, its repercussions will change the face of the world.
