A review of newly declassified U.S. naval communications intelligence (ComInt) records refutes attempts by revisionist conspiracy theorists to "prove" President Franklin D. Roosevelt knew of the Japanese plan to attack Pearl Harbor and withheld information to draw the United States into the European war. Evidence now corroborates a long-held view that Japanese radio deception masked movement of their carriers—here, the Akagi steams for Hawaii—effectively ensuring a surprise attack.
In the years after World War II, innumerable books and articles have focused on the question of how the Japanese were able to pull off their sneak attack on Pearl Harbor. Recently, a resurgence of popular revisionist books have been gobbled up by old Roosevelt haters, some supporters of the Pearl Harbor commanders, Husband E. Kimmel and Walter S. Short, groups of the younger generation who have a great distrust in their government since Watergate, and even present-day Japanese apologists. In addition, the conservative Internet chat boards are full of such Pearl Harbor conspiracy devotees.
