What am I missing here? The Cuban Missile Crisis occurred in 1962. It was the Soviets that backed down due to the US Naval blockade that kept them from supplying the Cuban missile buildup. Neither country wanted a nuke war, so it was settle with behind scenes diplomatic efforts that made it look like a stalemate and both nations kept face.
Also, JFK was assassinated in 1963. How could he have ANY involvement in 1967 with Jupiter missiles?
OP erred with dates.
In 1959, the United States and Turkey signed a mutual defense treaty, and the US began deploying nuclear-capable missiles in Turkey as part of its NATO commitments. The Jupiter missiles were deployed in Italy and Turkey in 1961, with the primary purpose of deterring a potential Soviet attack on Western Europe.
In a secret agreement, the US agreed to remove the Jupiter missiles from Turkey in exchange for the Soviet Union’s withdrawal of its missiles from Cuba. This agreement was reached through a series of back-channel negotiations between US Attorney General Robert Kennedy and Soviet Ambassador Anatoly Dobrynin.
