Amazon.ca: Secret Messages: Codebreaking and American Diplomacy, 1930-1945: Books: David J. Alvarez (Site not responding. Last check: 2007-10-13) |
 | | Secret Messages is a meticulously researched, carefully reasoned, and well-written account of the United States government's attack on the diplomatic communications of foreign governments from 1930 to 1945, an attack that produced the most valuable secret intelligence on foreign relations and national security that the United States possessed during this period. |
 | | Secret Messages is one of the first works to make extensive use of the Historic Cryptographic Collection (HCC), an enormous collection of nearly 1500 boxes of documents relating to United States cryptography and cryptanalysis before 1945 that was deposited into the United States National Archives by the National Security Agency in 1996. |
 | | Secret Messages is a significant contribution to the laying of the groundwork for a thorough revision of the history of United States foreign policy and national security policy during a most critical period. |
