This is a fantastic timeline. A couple questions, if I may, and sorry if they've already been asked: 1. how far are you going to take the effects of nuclear winter? There should be a couple hundred trillion grams of soot in the atmosphere, will there just be a succession of harsh winters, or something closer to a full-on ice age? 2. what's the state of India and Pakistan, were nuclear weapons exchanged there as well? I'm not sure that each country had many nukes by 83, and even less that they had robust delivery systems (especially Pakistan). 3. similarly, what about China? Was there an exchange between Russia and China, or China and the US? Anyway, please keep up the good work!
