Newly Declassified National Security Agency History Questions Early Vietnam War Communications Intelligence: "The largest U.S. intelligence agency, the National Security Agency, today declassified over 140 formerly top secret documents -- histories, chronologies, signals intelligence [SIGINT] reports, and oral history interviews -- on the August 1964 Gulf of Tonkin incident. Included in the release is a controversial article by Agency historian Robert J. Hanyok on SIGINT and the Tonkin Gulf which confirms what historians have long argued: that there was no second attack on U.S. ships in Tonkin on August 4, 1964. According to National Security Archive research fellow John Prados, 'the American people have long deserved to know the full truth about the Gulf of Tonkin incident. The National Security Agency is to be commended for releasing this piece of the puzzle. The parallels between the faulty intelligence on Tonkin Gulf and the manipulated intelligence used to justify the Iraq War make it all the more worthwhile to re-examine the events of August 1964 in light of new evidence.' Last year, Prados edited a National Security Archive briefing book which published for the first time some of the key intercepts from the Gulf of Tonkin crisis."
