The setup is this-JFK survives the assassination attempt in Texas, but Jackie Kennedy dies instead. The Soviet Union, thinking him weak and deciding to take advantage of the situation, sends new nukes to Cuba, causing a second Cuban Missile Crisis. After weeks of deliberation, an angry JFK decides to put a stop to this once and for all, and launches nuclear warheads at Cuba and the Soviet Union. My question is this-What would survive? With the advantage of surprise, what portions of the United States would survive the resultant war?
