One of the more interesting prospects of CMC alternate history is avoiding war, but not successfully removing the nuclear missiles from Cuba. This is a middle ground between total Armageddon and the peace that was won in the OTL, where there is a peace but a sword is now constantly at the throat of America where one wasn't before. I do believe Kennedy thought early on he wasn't going to be able to get the missiles removed from Cuba, before being told that Khrushchev would be open to it if he could say to his people he saved Cuba and Kennedy and the US would never invade. This proved to be the case.
But what if the Cuban Missile Crisis was resolved peacefully, but the missiles remained in Cuba?
