I completely agree with Edward Curtin.
Of course, Kennedy learned on the job. He started as a Cold Warrior. Exactly when he was referring to which dark forces within the US is not always easily discerned. That said, I have no doubt whatsoever that he was the best President the US ever had when weighted by his very short time in office. He didn't have nearly as long as FDR to try to turn the tide against utter plutocracy, but he was not as compromising as was FDR either. I don't say JFK was a democratic-socialist at heart, but I can't say he wasn't either. By democratic-socialist, I don't mean the fake Bernie Sanders version but the real deal.
I would be remiss if I didn’t point out one place where Griffin fails the reader. In his long chapter on Vietnam, which is replete with excellent facts and analyses, he makes a crucial mistake, which is unusual for him. This mistake appears in a four page section on President Kennedy’s policies on Vietnam. In those pages, Griffin relies on Noam Chomsky’s terrible book – Rethinking Camelot: JFK, the Vietnam War, and US Political Culture (1993), a book wherein Chomsky shows no regard for evidence or facts – to paint Kennedy as being in accord with his advisers, the CIA, and the military regarding Vietnam.
This is factually false. Griffin should have been more careful and have understood this. The truth is that Kennedy was besieged and surrounded by these demonic people, who were intent on isolating him, disregarding his instructions, and murdering him to achieve their goals in Vietnam. In the last year of his life, JFK had taken a radical turn toward peace-making, not only in Vietnam, but with the Soviet Union, Cuba, and around the globe. Such a turn was anathema to the war lovers. Thus he had to die.
Contrary to Chomsky’s deceptions, motivated by his hatred of Kennedy and perhaps something more sinister (he also backs the Warren Commission, thinks JFK’s assassination was no big deal, and accepts the patently false official version of the attacks of 11 September 2001), Griffin should have emphatically asserted that Kennedy had issued NSAM 263 on October 11, 1963 calling for the withdrawal of American troops from Vietnam, and that after he was assassinated a month later, Lyndon Johnson reversed that withdrawal order with NSAM 273.
