“... JFK stand up in Russia’s grill and blockade Cuba....”
The solution to the Cubna Missile Crisis was a bit of diplomatic tit-for-tat. We removed our Jupiter missiles (IRBMs) from Turkey (Which were there before the Castro regime!) they remove their versions of that type of missile from Cuba. Look at a map and you will see there’s not much difference range-wise. The JFK-LBJ administrations & cooperating media kept that information well buried and off the front page.
To be fair, the Turkey silos were also made obsolete as justification for their removal as well (in fact, if anything, we had even MORE legroom afterwards for striking against the USSR via IRBMs and even ICBMs via those nuclear powered subs, so the Soviets still in a sense lost).
