Mason Patrick Billy Mitchell Hawaii United States
Ever since the Japanese attack, there has been debate as to how and why the United States had been caught unaware, and how much and when American officials knew of Japanese plans and related topics. As early as 1924, Chief of U.S. Air Service Mason Patrick displayed a concern for military vulnerabilities in the Pacific, having sent General Billy Mitchell on a survey of the Pacific and the East. Patrick called Mitchell's subsequent report, which identified vulnerabilities in Hawaii, a "theoretical treatise on employment of airpower in the Pacific, which, in all probability undoubtedly will be of extreme value some 10 or 15 years hence".
