Agreeing to remove all of our Jupiter IRBMs from Turkey and Italy was anything but stern, Anna.
If the missiles are to be delivered by ship, I say wait until the vessel is somewhere over the Puerto Rico trench, (the second deepest ocean trench in the world), and put a heavy torpedo into her. An electronic warfare bird in the vicinity can make sure no “mayday” messages get out and suddenly we have another victim of the Bermuda Triangle.
Kennedy was looking to remove the Jupiter IRBM’s well before the Cuban Missile Crisis. The Jupiters were only intended as a stopgap until more reliable ICBM’s and SLBM’s were on line. The Jupiter was already obsolete in 1962. Liquid fueled, using cryogenic liquid oxygen as the oxidizer was the major risk. From go order to launch would be maybe one hour. Add the launchers were above ground fixed emplacements. So the missiles would likely never make it to launch if the balloon went up. The Soviets already knew the locations, the launch pads in Italy were overflown by Warsaw Pact reconnaisance planes.
About the same time the Minuteman missiles were coming on line (hardened silos, fast reaction time), and also the first Polaris submarine (even if they were in the East Med, try finding them, Admiral Gorschkov). One Polaris sub, with 16 missiles, sailing somewhere quantitatively replaced one Jupiter squadron. And we built 41 of them, plus the Royal Navy had theirs.
So getting rid of the Jupiters, already obsolete and an operational liability, turned out to me more of a face saving measure for Khrushchev.
The real reason why Khrushchev pulled the missiles out was not just Kennedy going to DEFCON 2, but also Castro and Che Guevara were seriously considering taking the missiles, launching, and starting WW3. A step that even Khrushchev would not take. Not the case though for Imadinnerjacket. He wants the nukes to fly, in order to bring forth his “Twelfth Imam”, and doesn’t care if his country is incinerated in the process. But also in this case, we do not have a President with the resolve to stand up to the threat. JFK was indeed ready to unleash Curtis Lemay.
The Jupiter missiles were reputed to not be that reliable or accurate anyway. It was really no great loss.
The Jupiter IRBM’s were due to be retired anyway, being kerosene and liquid oxygen fueled as well as being land based non-hardened installations. The former made for reliability problems and longer response times. The latter - the Soviets knew their locations, in fact the missiles in Italy were overflown by a reconnaissance MiG. Our first generation SSBN’s were coming on line then, a more than even replacement. The Jupiter and Thor IRBM’s were only intended as a stop gap until the first generation ICBM’s (Atlas, Titan I) came on line.
The real reason the missiles were pulled out of Cuba was because Castro and Guevara wanted to take control of them and launch them. That scared the crap out of Khruschev.
