One of the most important assertions, and a point of controversy for historians when this book first came out, is that Dallek did not think Kennedy's presidency was damaged by his risky sexual behavior and bad health.
Upon reading though, just the panoply alone of drugs and injections was enough to convince me that Kennedy at least suffered a great deal. The evidence that he was conclusively and negatively effected by the drugs is not clear, it may never be. But, I found it alarming that so many physicians ruthlessly medicated the man without offering genuine relief.
Kennedy may be likened rather to a well-trained athlete who is medicated and medically treated beyond the norm. People can still function, even out-perform those around them. Kennedy had an incredible will; I think he really rose to the situation, he really was a war hero on PT 109. His endurance and commitment to his men after his boat was split in two by a Japanese warship is impressive. On the other hand, I don't think sinking into hero worship is sound, he certainly had his share of mistakes such as the Bay of Pigs, he just seemed to be a high-performing individual, warts and all.
As to the sex, well, I certainly was not aware of it at the time but enough evidence came to light over the years. I guess he enjoyed himself.
Dallek obtained documents indicating Kennedy had an affair with a 19-year-old intern in the White House: shades of Bill Clinton. He discovered 17 blacked-out pages in an oral history by Barbara Gamarekian, who was an aide to Kennedy Press Secretary Pierre Salinger.
Gamarekian refused to give him the name of the former intern to protect the woman but the pages were from 40 years ago so authentic enough. In fact, the New York Daily News subsequently learned the woman's identity and published an interview with her.
Many Americans consider Kennedy to be among the greatest presidents, but Dallek says most historians would dispute that, he fell well short of great or even near great. He failed to win passage for civil rights legislation and other major legislative initiatives and he stumbled in foreign policy with the Bay of Pigs and an escalation of the Vietnam War, Dallek stated in interviews about the book.
The assassination colors our perception. Kennedy has tended to be idolized as a result. Since I finally got around to the book I believe it is well worth reading and certainly presents a human presidential figure.
