Killing Kennedy

a condition known as autoimmune polyendocrine syndrome type 2 (APS-2), which has caused not only his hypothyroidism (insufficient thyroid hormone) but also his Addison’s disease, which must be closely monitored at all times. Addison’s causes his body to fail to produce the necessary hormones, such as cortisol, that regulate blood pressure, cardiovascular function, and blood sugar. Left unchecked, Addison’s causes exhaustion, weight loss, weakness, and even death. In 1946, before the disease was diagnosed, Kennedy collapsed at a parade and turned so blue and yellow that he was thought to be suffering from a heart attack.
    That must not happen now.
    So JFK is receiving injections of hydrocortisone and testosterone to battle his Addison’s. He is taking antispasmodic drugs to ward off his chronic colitis and diarrhea. And the president is suffering from another painful urinary tract infection, which requires antibiotics. All of this is in addition to relentless excruciating back pain. A less driven man would have taken to bed long ago, but John Kennedy refuses to let his constant pain and suffering interfere with his performing his duties.
    Jackie has chosen not to worry about Jack’s fatigue, having seen him drive himself hard through many a campaign, attending a fund-raising dinner until late in the night and then waking up before dawn to stand outside some factory or steel mill to shake hands with the workers arriving for their shift. But this is different, and she doesn’t know how much longer he can go on. She sees the awkward way he eases himself into his favorite rocking chair for meetings to lessen the pain in his back.
    More ominously, Jackie knows about the time his Addison’s almost killed him, fifteen years earlier. She also remembers that, in 1954, a metal plate was inserted into her husband’s spine (to counter a degenerative condition) and a postoperative infection put him in a coma. Once again, John Kennedy was administered the last rites of the Roman Catholic Church. And once again he battled back.
    That makes three times—PT-109, Addison’s, and the back surgery—in which JFK defeated death. Jackie Kennedy knows that her man, the president of the United States, is extremely tough. He will persevere. He always has.
    But it’s actually the men of ExComm who have the First Lady concerned. Jackie has pressed her ear to the door and eavesdropped on their meetings. She has heard the strain. She believes these men are working to “the peak of human endurance” to save the world.
    McGeorge Bundy, too, is quite sure that the ExComm men are all about to crack. They’ve been awake night and day for almost two weeks. These staid men have become emotional because of their extreme exhaustion and have cultivated opinions and petty jealousies that will define their relationships for years to come. One of the most powerful voices among them is that of air force general Curtis E. LeMay, who sees nothing wrong with blowing Cuba off the map.

    Then Khrushchev’s message arrives. The letter’s wording is personal, an appeal from one leader to another to do the right thing. The Soviet leader insists that he is not trying to incite nuclear war: “Only lunatics or suicides, who themselves want to perish and to destroy the whole world before they die, could do this,” he writes. The Soviet ruler rambles on, questioning Kennedy’s motivations.
    Khrushchev concludes his letter by negotiating with Kennedy in a somewhat confusing fashion. The paragraph that draws the most attention states: If you have not lost your self-control, and sensibly conceive what this might lead to, then, Mr. President, we and you ought not to pull on the ends of the rope in which you have tied the knot of war, because the more the two of us pull, the tighter the knot will be tied. And a moment may come when that knot will be tied so tight that even he who tied it will not have the strength to untie it, and then it will be necessary to cut that knot.”
    The ExComm crew does not believe that Khrushchev’s message is the sign of an outright capitulation. But they all agree it’s a start.
    For the first time in more than a week, John F. Kennedy feels hopeful. Yet he does not lift the blockade. There are still nearly a dozen Soviet vessels steering directly toward the quarantine line—and these ships show no signs of turning around.
    The tension increases the next afternoon, when word reaches JFK that Cuban
