> The SIGINT also shows, according to Hanyok, that a second attack, on August 4, 1964, by North Vietnamese torpedo boats on U.S. ships, did not occur despite claims to the contrary by the Johnson administration. President Johnson and Secretary of Defense McNamara treated Agency SIGINT reports as vital evidence of a second attack and used this claim to support retaliatory air strikes and to buttress the administration's request for a Congressional resolution that would give the White House freedom of action in Vietnam.

This is exactly what I said.

> Hanyok further argues that Agency officials had "mishandled" SIGINT concerning the events of August 4 and provided top level officials with "skewed" intelligence supporting claims of an August 4 attack. "The overwhelming body of reports, if used, would have told the story that no attack occurred." Key pieces of evidence are missing from the Agency's archives, such as the original decrypted Vietnamese text of a document that played an important role in the White House's case. Hanyok has not found a "smoking gun" to demonstrate a cover-up but believes that the evidence suggests "an active effort to make SIGINT fit the claim of what happened during the evening of 4 August in the Gulf of Tonkin." Senior officials at the Agency, the Pentagon, and the White House were none the wiser about the gaps in the intelligence. Hanyok's conclusions have sparked controversy among old Agency hands but his research confirms the insight of journalist I.F. Stone, who questioned the second attack only weeks after the events. Hanyok's article is part of a larger study on the National Security Agency and the Vietnam War, "Spartans in Darkness," which is the subject of a pending FOIA request by the National Security Archive.

To figure out who the liars are we need to know who engaged in a cover-up. Who manipulated, withheld information, or lied. You already know my opinion: I don't think it was the NSA.

For example "The overwhelming body of reports, if used, would have told the story that no attack occurred" suggests that the NSA's information was, in fact, good. It just was ignored, manipulated, omitted, etc.
