ABSTRACT In an effort to support its massive conspiracy theory headed by President Franklin D. Roosevelt to get the United States into the European war and it continuing cover-up, Day of Deceit misinterprets, misstates, and omits much of the old and some new cryptologic information surrounding the Japanese attack on Pearl Harbor. In spite of this huge research effort by the author, Robert B. Sinnett, it is still clear that no U. S. official knew about the attack beforehand. 相似文献

In early February, 1942, Commander M. E. Miles proposed the establishment of a radio intelligence unit in China. His proposal led to the creation of Naval Group China (NGC), the umbrella organization for units that performed weather forecasting, advised and trained Chinese guerillas, and intercepted and analyzed Japanese radio traffic. NGC was part of the Sino-American Cooperative Organization (SACO). Most of the commitments of China and NGC were formalized on 15 April 1943 with the signing of the Sino-American Cooperative Agreement (SACO). Article 18 required further delicate negotiations between Miles and General Tai Li, head of the Bureau of Investigation and Statistics (China's secret service). Miles was soon trapped between his commitment to Tai Li and Joseph Wenger's concern that any intercepted traffic shared with the Chinese would quickly become available to the Japanese via insecure Chinese codes. Fleet Radio Unit, China (FRUCHI) resolved this dilemma. 相似文献

Recently declassified documents from the “Crane Collection” at the National Archives (USA) reveal much of the purpose of Alan Turing's visit to the United States during the Winter of 1942–1943. The “Bombe Correspondence” file contains Turing's “Visit To National Cash Register Corporation of Dayton, Ohio” and additional material which places this report and his earlier “Treatise on the Enigma” in the context of his role as consultant to the U. S. Navy Cryptanalytic Section (Op-20-G) on the design of the Navy Bombe and other related matters. The documents in this collection reveal a productive and decisive relationship between Turing and Op-20-G dating from the visit of the Sinkov mission to Bletchley Park in February 1941. 相似文献
