DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKOn December 7, 1941, the course of U.S. history changed forever with the bombing of Pearl Harbor. Three weeks prior, Japanese Special Envoy to the United States Saburo Kurusu visited Washington in an attempt to further peace talks between Japan and America and spare his country the loss he knew would occur if a war began. But as he reported, “Working for peace is not as simple as starting a war.” For more than seventy years, many have unfairly viewed Kurusu and his visit as part of the Pearl Harbor plot. Editors J. Garry Clifford and Masako R. Okura seek to dispel this myth with their edition of Kurusu’s memoir, The Desperate Diplomat. Kurusu published his personal memoir in 1952, in Japanese, describing his efforts to prevent war between the two nations, his total lack of knowledge regarding the Pearl Harbor attack, and what “might have been” had he been successful in his endeavor for peace, while offering an exclusive perspective on the Japanese reaction to the attack. However, the information contained in his memoir was unavailable to most of the world, save those fluent in Japanese, because it had never been published in another language. With the discovery of Kurusu’s own English memoir, his story can finally be told to a wider audience. Clifford and Okura have used both the Japanese and English memoirs and added an introduction and annotations to Kurusu’s story, making The Desperate Diplomat an essential look at an event that remains controversial in the history of both nations. Anyone who takes interest in the history of Pearl Harbor cannot afford to omit this previously unavailable information from their library.

DOWNLOAD EBOOKWhile 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.

DOWNLOAD EBOOKIn this absorbing account of the origins of the Asia-Pacific War, historian John Gripentrog argues that competing ideologies of world order—chiefly the rift between liberal internationalism and Pan-Asian regionalism—lay at the heart of the conflict. Drawing from a rich diversity of primary and secondary sources, the author also examines the Japanese government’s vigorous cultural diplomacy in the U.S., which sought to win over American hearts and minds and soft-pedal its imperialist ambitions in Asia. The result is a book that both challenges and amplifies standard interpretations of US-Japan relations in the interwar era, while weaving diplomatic, political, intellectual, and cultural history. Moreover, the author’s wide-angle lens offers readers insights into a fascinating assemblage of historical actors—from Japanese and American diplomats, politicians, and military leaders, to cosmopolitan art enthusiasts and major league baseball players.

DOWNLOAD EBOOKProtesters called it an act of war when the U.S. Coast Guard sank a Canadian-flagged vessel in the Gulf of Mexico in 1929. It took a cool-headed codebreaker solving a "trunk-full" of smugglers' encrypted messages to get Uncle Sam out of the mess: Elizebeth Smith Friedman's groundbreaking work helped prove the boat was owned by American gangsters. This book traces the career of a legendary U.S. law enforcement agent, from her work for the Allies during World War I through Prohibition, when she faced danger from mobsters while testifying in high profile trials. Friedman founded the cryptanalysis unit that provided evidence against American rum runners and Chinese drug smugglers. During World War II, her decryptions brought a Japanese spy to justice and her Coast Guard unit solved the Enigma ciphers of German spies. Friedman's "all source intelligence" model is still used by law enforcement and counterterrorism agencies against 21st century threats.

DOWNLOAD EBOOKWith war on the horizon in the late 1930s, many Americans, still angry over the outcome of the Great War, determined not to get involved in another global conflict. Called isolationists or anti-interventionists, many of them, especially the America First Committee, focused their attention on the European war when it broke out in September 1939. Most were less interested in Japan’s aggression in East Asia, which left an opening for another isolationist group, the Committee on Pacific Relations, which opposed war with Japan right up to the day of the Japanese attack on Pearl Harbor. In this first full study of pro-Japan isolationists, Roger B. Jeans provides a detailed history of the committee, which was launched in September 1941, a scant ten weeks before the beginning of the war. Its driving force was Missourian Orland Kay “O. K.” Armstrong, who traveled widely during the late 1930s and early 1940s recruiting prominent Americans for his movement against war with Japan. He and his colleagues were often critical of US policies and of China, the victim of Japanese aggression. As a result, they were often ostracized as pro-Japanese. Jeans draws on previously untapped sources—the personal letters of committee members and the dossiers the FBI compiled on them—to paint a rich picture of this little-known group.
