• “In what, then, can those engaged in this kind of warfare place their hope? The Nakano Military School answered this question with a simple sentence: “In secret warfare, there is integrity.” And this is right, for integrity is the greatest necessity when a man must deceive not only his enemies but his friends. With integrity—and I include in this sincerity, loyalty, devotion to duty and a sense of morality—one can withstand all hardships and ultimately turn hardship itself into victory. This was the lesson that the instructors at Futamata were constantly trying to instill in us. One of them put it this way: “If you are genuinely pure in spirit, people will respond to you and cooperate with you.” This meant to me that so long as I remained pure inside, whatever measures I saw fit to take would eventually redound to the good of my country and my countrymen.”
