I'm sure this one has been beat to death, but I'm wondering if there are thoughts for scenarios where the Cuban Missile Crisis not only turns hot, but the war doesn't completely destroy the NATO and Warsaw powers. Certainly, if it went hot, there would be limited use of atomic weapons in the American South, Cuba, and probably Eastern Europe, but I wonder if major combat operations could be largely convention and could take place in Central Europe (including Italy and throughout Germany), the Pacific Rim (Taiwan, Korea, Vietnam, Indonesia), and also throughout major hotspots in Central and Southwestern Asia (I'm thinking here of the simultaneous Sino-Indian War and among unstable US-allies like Turkey, Iraq, and Iran). Plus, of course, the naval engagements in the Atlantic and the Pacific.
Plausible?
