Sorry, but I don't agree with the context. I don't see the relevance of MLK, that's the same as me saying "MLK would not have happened if his parents had not had sex." And of course it was "political", it generally is.
Neither does JFK's family wealth have anything to do with it...as I pointed out earlier some of our very best presidents were very wealthy.
Ditto for his Father wanting Joe, who was killed, as his first choice.
As far as Viet Nam, that was mostly Eisenhower's doing...Yes, Kennedy ramped it up some but Johnson did it on a much larger scale. During Kennedy's last year US troops numbered approximately 16300....Johnson's last year the troops numbered 536100.
And I already covered the Bay of Pigs...besides, that was Eisenhower's baby as well. Was Kennedy to blame, well yes, because he was the Commander if Chief and he openly admitted that he would accept the blame. Eisenhower was the one who hooked up with the CIA to formulate a plan to oust Castro. JFK took over and voiced his apprehension about the plan presented to him by the CIA...but finally gave the go ahead...he had some VERY bad intel.
