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.

Putin...? He'd get a lot more mileage if he'd smile.
