Source: "Stanley Washburn of Lakewood, New Jersey, a newspaperman, a soldier, a propagandist, and a former Republican candidate for Congress, had just written to fellow Republican Frank Knox to offer a voice of Far East experience. Apparently during his newspapering days, Washburn had covered the Russo-Japanese War, and he told Knox in a letter on November 29 not to underestimate the Japanese. He had seen them in action, and they were smart, committed, cre- ative, and willing to die. "In my experience, the Japanese never do what they're expected to do," Washburn warned. Knox thought enough of Washburn's wisdom and credentials to pass the letter to Harold Stark. On Tuesday, December 2, Stark put a copy in the mail for Kimmel. By the time it arrived, its prediction was reality." from Twomey, Steve (21 November 2017). Countdown to Pearl Harbor: The Twelve Days to the Attack. Simon and Schuster. p. 190.
