Five decades later, the assassination of John F. Kennedy remains one of the few utterly signal events from the second half of the 20th century. Other moments — some thrilling (the moon landing, the fall of the Berlin Wall), others horrifying (the killings of Martin Luther King Jr. and Robert Kennedy, the Challenger explosion) — have secured their places in the history books and, even more indelibly, in the memories of those who witnessed them. But nothing in the latter part of “the American century” defined an era as profoundly as the rifle shots that split the warm Dallas air on November 22, 1963, and the sudden death of the 46-year-old president.
There was Camelot — a media construct, of course, but a rarity in that it actually resonated with so many people, everywhere — and then there was the somber, profoundly uncertain period after Camelot. For countless millions in America and around the globe who lived through the near-surreal transition, the days and weeks after JFK’s assassination felt like a chilling, restless pause: a moment so charged with unease that even reflection, or taking stock, seemed impossible.
