Perhaps, because I have chosen to approach something I wasn't qualified to read: I wasn't born in America, but lived here enough though to be interested in life and death of President John F. Kennedy, this material was "too much to chew" for me.
However, the author evolves all the events around one thing and one thing only: the Bay of Pigs... As well as pointing blame for all unsuccessful escapades and coup against Communist regime of Cuba...on President Kennedy. I think, it's totally unfair, plus, small portion of the text devoted to assassination of President, is also negligent in details, reasons and sources...As far as "coloring" the President's private life, I would first of all omit the suggestions about him being a "womanizer" and if it's already done by author, then bring forward that of his spouse, as well. Also, President suffered immeasurable awful pain in his back. Constantly !. For which he had to take strong medications, possibly narcotics-proscribed by doctor. These medications Do tend to effect one's attitude, state of mind and moods as they accumulate in brain matter. So to me, the book didn't answer questions I had and left confused. But then, again, I may have been not qualified for it. Anyway, I found it very one-sided.
