Was McNamara A Traitor To JFK ???

From watching the movie Thirteen Days, one might get the impression that Robert McNamara aided JFK in his fight to keep the Cuban missile crisis from escalating into a nuclear war. And perhaps he did.

But ... what effect did that scary episode have on Bob? Might he and his former boss, Curtis LeMay, then have decided that JFK had to go?

Read this assessment by Gareth Porter of how McNamara later deceived LBJ into bombing Vietnam following the Gulf of Tonkin incident. Why would a person who wanted to avoid war have done such a thing?

Keep in mind that on the eve of the murder of JFK, at least two key groups of conspirators met to seal the President's fate:

• LBJ, Nixon, J. Edgar Hoover, and the Texas oilmen met with Clint Murchison, Sr. at the latter's home in Dallas; and
• McNamara, Dean Rusk, and Henry Cabot Lodge, Jr. met with military leaders in Honolulu.

Lodge had just arranged the murder of President Ngô Đình Diệm of South Vietnam along with his brother and adviser Ngô Đình Nhu. It is quite believable that he was one of the ringleaders of the plot to then murder JFK. And McNamara was right there with him to discuss their plans for war in Vietnam after JFK was out of the way:

Someone rallied top US military leaders into the JFK assassination plot. It may have been LeMay, or as in the murder of Julius Caesar it may have been several of them. But wouldn't  McNamara, an anal hands-on kind of leader, at least have been suspicious of what was going on?

Or was he one of the rats that brought it all together?
