Now, I like to label all sorts of things as "fun read," but there is a limit. I was about to say "hey, fun read!" but then thought better of it. So read "Timeline 9: "The Big D" - what if "the mid-east war escalated and the tensions between the superpowers grew. March 17, 1979 nuclear war broke out: Egyptian missiles with Soviet warheads struck against Israel ..." (read it) This is indeed one of the most detailed and enlightening "alternative future" scenarios that I've seen.
