This is the story of the U.S. Navy's communications intelligence (COMINT) effort between 1924 and 1941. It races the building of a program, under the Director of Naval Communications (OP-20), which extracted both radio and traffic intelligence from foreign military, commercial, and diplomatic communications. It shows the development of a small but remarkable organization (OP-20-G) which, by 1937, could clearly see the military, political, and even the international implications of effective cryptography and successful cryptanalysis at a time when radio communications were passing from infancy to childhood and Navy war planning was restricted to tactical situations. It also illustrates an organization plagues from its inception by shortages in money, manpower, and equipment, total absence of a secure, dedicated communications system, little real support or tasking from higher command authorities, and major imbalances between collection and processing capabilities. It explains how, in 1941, as a result of these problems, compounded by the stresses and exigencies of the time, the effort misplaced its focus from Japanese Navy traffic to Japanese diplomatic messages. Had Navy cryptanalysts been ordered to concentrate on the Japanese naval messages rather than Japanese diplomatic traffic, the United States would have had a much clearer picture of the Japanese military buildup and, with the warning provided by these messages, might have avoided the disaster of Pearl Harbor.
Traces events leading up to and resulting from the December 7, 1941, Japanese attack on American battleships at Pearl Harbor, which brought the United States into World War II.
While the United States has had some kind of intelligence capability throughout its history, its intelligence apparatus is young, dating only to the period immediately after World War II. Yet, in that short a time, it has undergone enormous changes—from the labor-intensive espionage and covert action establishment of the 1950s to a modern enterprise that relies heavily on electronic data, technology, satellites, airborne collection platforms, and unmanned aerial vehicles, to name a few. This second edition covers the history of United States intelligence, and includes several key features: Chronology Introductory essay Appendixes Bibliography Over 600 cross-referenced entries on key events, issues, people, operations, laws, regulations This book is an excellent access point for members of the intelligence community; students, scholars, and historians; legal experts; and general readers wanting to know more about the history of U.S. intelligence.
A companion to World War II in Europe, Africa, and the Americas, this volume reevaluates the most enduring literature on basic aspects of the war in Asia and the Pacific. It also covers themes pertaining to societies at war, culture, the arts, and science and technology as well as international relations and the postwar world. Included are not only grand strategy, military and naval campaigns, and matters of diplomacy, but also resistance, collaboration, prisoners of war, and broad topics of the home front, including chapters on gender issues, film, literature, popular culture, and propaganda. This volume and its companion provide the first comprehensive historiographic reference work on the war. Each chapter describes the state of knowledge on the topic, relating each bibliographic reference to the chapter's themes and issues, and concludes with a bibliography. Recent original scholarship is included when it aids new understanding, and older works of enduring value also find a place. The essays in this volume will interest scholars and college teachers as well as advanced students and serious amateurs seeking insight into the history of the war and its literature.
Explores the causes and effects of the battle and provides first-hand accounts from the people who were there, including Japanese and Americans, military and civilian.
