Based on the assertion that such an attack had occurred, President Lyndon B. Johnson ordered airstrikes on North Vietnam and Congress passed a broad resolution authorizing military action.
Some intelligence officials said they believed the article’s release was delayed because the agency was wary of comparisons between the roles of flawed intelligence in the Vietnam War and in the war in Iraq. …
Fearful of comparisons with Iraq? Over an alleged false flag attack? Sounds like a guilty conscience on someone’s part. That whole “no need for truth in government” really make neoconservtism look like it’s hiding something.
