Gulf of Tonkin Second Incident: Post-1968 Reviews of Misattribution Discussions

SUMMARY

The claim that the second Gulf of Tonkin incident in August 1964 was misattributed or fabricated is a significant point of contention in the historical record of the Vietnam War. While some sources assert that no second attack occurred and that evidence points to deliberate deception, official U.S. government positions initially maintained both attacks were genuine. Subsequent declassifications and investigations, notably by the National Security Agency (NSA), have cast doubt on the occurrence of the second attack. The current investigation seeks to determine if there are documented internal military or intelligence agency reviews from after 1968 that specifically detail discussions among 1964 participants regarding the misattribution of this second incident, rather than general acknowledgments of non-occurrence. Accessing such records would illuminate the internal understanding and handling of this intelligence failure or deception.

STRONGEST CASE FOR

The strongest case for the existence of such records is that the intelligence community, having acknowledged the misattribution of the second Gulf of Tonkin incident, would have conducted internal reviews to understand how such a critical error or deception occurred. These reviews would likely involve participants from the 1964 events to gather their perspectives on the intelligence received and processed at the time, especially given the significant political and military consequences that followed. Agencies like the CIA and military branches are known to conduct historical reviews and declassify records, which might include such discussions.

STRONGEST CASE AGAINST

The strongest argument against the existence or accessibility of such specific records is that, while the non-occurrence of the second incident has been acknowledged, a direct internal review detailing discussions among 1964 participants about 'misattribution' in a post-1968 context may not have been formally documented or declassified. Agencies might have preferred to address the factual error without explicitly detailing internal discussions that could imply deliberate falsification or widespread incompetence. Furthermore, the extensive destruction of some intelligence records, as seen in other programs, could mean such sensitive discussions were not preserved.
