An interesting alternative history novel, what if the cold war and the Cuban missile crisis had resulted in a nuclear war ?

Any similarity to current events is purely coincidental of course. Out of print, but decent used copies are readily available on fleabay etc.

Sounds like it needs a sequel, set in 2050ish.

I expect many problems of the world, especially environmental, those related to overshoot, would be better in the 2050-2100 timeframe had we had a thermonuclear war in the 1960s.
