s/t: How Their Secret Deals & Strategic Blunders Caused Disasters at Pearl Harbor & the Philippines Now, drawing on recently declassified American and British top-secret documents, New York Times bestselling historian John Costello reveals how major strategic and diplomatic miscalculations by Franklin D. Roosevelt and Winston S. Churchill together with the military blunders committed by General MacArthur set the stage for Japan's successful attacks on Pearl Harbor and Clark Field. For the first time, he documents how it was the devastating loss of air power in the Philippines - and not the battleships lost at Pearl - which permitted Japan's lightning conquest of the Far East in 1942.
