Editing Isoroku Yamamoto's sleeping giant quote (section)

==Overview==
The director of ''Tora! Tora! Tora!'', [[Richard Fleischer]], stated that while Yamamoto may never have said those words, the film's producer, [[Elmo Williams]], had found the line written in Yamamoto's diary. Williams, in turn, has stated that Larry Forrester, the screenwriter, found a 1943 letter from Yamamoto to the Admiralty in Tokyo containing the quotation. However, Forrester cannot produce the letter, nor can anyone else, American or Japanese, recall it or find it. [[Randall Wallace]], the screenwriter of the 2001 film ''Pearl Harbor'', readily admitted that he copied the line from ''Tora! Tora! Tora!''

Yamamoto did believe that Japan could not win a protracted war with the United States. Moreover, he seemed later to have believed that the Pearl Harbor attack had been a blunder strategically, morally, and politically, even though he was the person who originated the idea of a surprise attack on the military installation. It is recorded that while all his staff members were celebrating, "Yamamoto alone" spent the day after Pearl Harbor "sunk in apparent depression".<ref>''The Reluctant Admiral'', p. 259</ref> Yamamoto was upset by the [[Attack_on_Pearl_Harbor#Japanese_declaration_of_war|bungling]] of the [[Ministry of Foreign Affairs (Japan)|Foreign Ministry]], which led to the attack happening while the countries were still at peace, thus, along with other factors, making the incident an unprovoked surprise attack that enraged American public opinion.<ref>Haruko Taya Cook, Theodore F.
