WWII/U.S. INVASION OF JAPAN/A-BOMB DECISION MILITARY FILES

118 pages of U.S. military files covering the final months of the war with Japan, archived on CD-ROM. Documents cover U.S. invasion of Japan planning and the A-Bomb decision.

Files show the MacArthur/Nimitz rivalry over command control and military planners' sensitivity about confronting President Truman over casualty estimates, a total estimate of roughly "a quarter of a million."

Documents include coverage of anticipated Japanese reaction to an invasion of southern Kyushu, details of the planned campaign against Japan (codenamed Operation Olympic), cables to Potsdam regarding the A-Bomb test of 16 July, and instruction to General Carl Spaatz on use of the atomic bomb against a Japanese target.

CD also contains 20 pages of correspondences between Einstein, Franklin Roosevelt, Roosevelt advisor Alexander Sachs and Manhattan Project Director Vannevar Bush, relating to the creation of the Manhattan Project. In August, 1939, Albert Einstein sent a letter to President Franklin Roosevelt warning that Nazi Germany was attempting to build a new weapon which was more powerful and more destructive than any weapon ever known to mankind.
