tangent: I don't know if you have ever seen Noam Chomsky discuss Kennedy's decisions at that point, but I think it is the only topic I've ever seen him visibly furious over.
This [1] is probably not the talk you have seen, at least I would not describe Chomsky as furious in that clip. But I was not aware - maybe I once knew and forgot - that removing the missiles from Turkey was not really a concession but planned anyway because they were obsolete.
