The president’s friend Paul Fay, Jr., told of an incident that showed
JFK was keenly conscious of the peril of a military coup d’état. One
summer weekend in 1962 while out sailing with friends, Kennedy was asked
what he thought of Seven Days in May, a best-selling novel that
described a military takeover in the United States. JFK said he would
read the book. He did so that night. The next day Kennedy discussed with
his friends the possibility of their seeing such a coup in the United
States. Consider that he said these words after the failed Bay of Pigs
invasion and before the Cuban Missile Crisis:
"It’s possible. It could happen in this country, but the conditions
would have to be just right. If, for example, the country had a young
President, and he had a Bay of Pigs, there would be a certain
uneasiness. Maybe the military would do a little criticizing behind his
back, but this would be written off as the usual military
dissatisfaction with civilian control. Then if there were another Bay of
Pigs, the reaction of the country would be, ‘Is he too young and
inexperienced?’ The military would almost feel that it was their
patriotic obligation to stand ready to preserve the integrity of the
nation, and only God knows just what segment of democracy they would be
defending if they overthrew the elected establishment.”
Pausing a moment, he went on, "Then, if there were a third Bay of Pigs,
it could happen." Waiting again until his listeners absorbed his
meaning, he concluded with an old Navy phrase, "But it won’t happen on
my watch."
On another occasion Kennedy said of the novel’s plot about a few
military commanders taking over the country, "I know a couple who might
wish they could." The statement is cited by biographer Theodore Sorensen
as a joke. However, John Kennedy used humor in pointed ways, and
Sorensen’s preceding sentence is not a joke: "Communications between the
Chiefs of Staff and their Commander in Chief remained unsatisfactory
for a large part of his term."
Director John Frankenheimer was encouraged by President Kennedy to film
Seven Days in May "as a warning to the republic." Frankenheimer said,
"The Pentagon didn’t want it done. Kennedy said that when we wanted to
shoot at the White House he would conveniently go to Hyannis Port that
weekend."
