This book explores the American use of atomic bombs and the role these weapons played in the defeat of the Japanese Empire in World War II. It focuses on President Harry S. Truman's decision-making regarding this most controversial of all his decisions. The book relies on notable archival research and the best and most recent scholarship on the subject to fashion an incisive overview that is fair and forceful in its judgments. This study addresses a subject that has been much debated among historians and it confronts head-on the highly disputed claim that the Truman administration practised 'atomic diplomacy'. The book goes beyond its central historical analysis to ask whether it was morally right for the United States to use these terrible weapons against Hiroshima and Nagasaki. It also provides a balanced evaluation of the relationship between atomic weapons and the origins of the Cold War.

Many myths have grown up around President Harry S. Truman's decision to use nuclear weapons against Imperial Japan. In destroying these myths, Truman and the Bomb will discomfort both Truman's critics and his supporters, and force historians to reexamine what they think they know about the end of the Pacific War. Myth: Truman didn't know of the atomic bomb's development before he became president. Fact: Truman's knowledge of the bomb is revealed in his own carefully worded letters to a Senate colleague and specifically discussed in the correspondence between the army officers assigned to his Senate investigating committee. Myth: The huge casualty estimates cited by Truman and Secretary of War Henry Stimson were a postwar creation devised to hide their guilt for killing thousands of defenseless civilians. Fact: The flagrantly misrepresented "low" numbers are based on narrow slices of highly qualified--and limited--U.S. Army projections printed in a variety of briefing documents and are not from the actual invasion planning against Japan. Myth: Truman wanted to defeat Japan without any assistance from the Soviet Union and to freeze the USSR out of the postwar settlements. Fact: President Franklin D. Roosevelt and President Truman desperately wanted Stalin's involvement in the bloody endgame of World War II and worked diligently--and successfully--toward that end. Using previously unpublished material, D. M. Giangreco busts these myths and more. An award-winning historian and expert on Truman, Giangreco is perfectly situated to debunk the many deep-rooted falsehoods about the roles played by American, Soviet, and Japanese leaders during the end of the World War II in the Pacific. Truman and the Bomb, a concise yet comprehensive study of Truman's decision to use the atomic bomb, will prove to be a classic for studying presidential politics and influence on atomic warfare and its military and diplomatic components. Making this book particularly valuable for professors and students as well as for military, diplomatic, and presidential historians and history buffs are extensive primary source materials, including the planned U.S. naval and air operations in support of the Soviet invasion of Manchuria. These documents support Giangreco's arguments while enabling the reader to enter the mindsets of Truman and his administration as well as the war's key Allied participants.

A "behind-the-scenes account of the 116 days leading up to the Americans attack on Hiroshima"--Dust jacket flap.

"Nuclear weapons, since their conception, have been the subject of secrecy. In the months after the dropping of the atomic bombs on Hiroshima and Nagasaki, the American scientific establishment, the American government, and the American public all wrestled with what was called the "problem of secrecy," wondering not only whether secrecy was appropriate and effective as a means of controlling this new technology but also whether it was compatible with the country's core values. Out of a messy context of propaganda, confusion, spy scares, and the grave counsel of competing groups of scientists, what historian Alex Wellerstein calls a "new regime of secrecy" was put into place. It was unlike any other previous or since. Nuclear secrets were given their own unique legal designation in American law ("restricted data"), one that operates differently than all other forms of national security classification and exists to this day. Drawing on massive amounts of declassified files, including records released by the government for the first time at the author's request, Restricted Data is a narrative account of nuclear secrecy and the tensions and uncertainty that built as the Cold War continued. In the US, both science and democracy are pitted against nuclear secrecy, and this makes its history uniquely compelling and timely"--
