Hi,
A very interesting timeline! But I think everything was going to move much more quickly towards disaster after the USA nukes Havana. (Oct 29).
...
If the disturbance spreads to Western Europe, it would introduce discord at the worst moment, when the West needs to be united the most. The Soviets would have a propaganda field day. It is difficult to say what would happen. Anyway, just to point out that the Havana bomb would be a great error: it would initiate the war, no doubt.
Good points. As the political, economic, industrial, and military center of Cuba, you're absolutely right. It's a big step in escalation for Kennedy, and you're absolutely right about the fact that the destruction of Havana isn't necessary for the invasion -- in this TL, it simply helps the invasion.
The choice of Havana is twofold -- it limits the retaliation to Cuba, thus reducing the chance that the war will spread. It also eliminates the Cuban government, potentially a decapitating stroke and potentially allowing American forces to march in with no resistance. While that's not going to happen, the potential is there.
The problem is that Kennedy can't afford to worry about Europe or things outside Cuba right now -- only when the situation is solved can he worry about the consequences. For the people pressuring Kennedy, Cuba is the issue, not the Warsaw Pact in general. Kennedy doesn't know if Krushchev will be willing to throw away Cuba or not. He's taking a risk in hopes of bringing the conflict to a quick end. It's a risk that doesn't pay off, but it's one I think he would make. He's laying his cards down on the table and is blatantly asking Krushchev if he thinks Havana is worth Moscow.
Kennedy doesn't know about the inside pressure, the other forces at work. In a situation where Krushchev is firmly in control, he'd be able to say no, that Cuba isn't worth the destruction of the Soviet Union, and damn the consequences as long as the Soviet Union gets to live. Krushchev's in a hard spot -- he knows that he's at a nuclear disadvantage, knows that Kennedy knows that he is, and Kennedy knows that he knows that Kennedy knows. Kennedy's got the upper hand, and the destruction of Havana puts it squarely in Krushchev's court.
Krushchev's still got an out -- he can say that the conflict is purely between Cuba and the United States. Most folks won't buy it, but it's better than an unlimited nuclear war, one that he knows the Soviet Union will lose.
Of course, the coup prevents a potential end to the situation. The Plotters don't know what Krushchev knows, and so they think they can continue the escalation and still win. They're tragically mistaken.
