It's interesting for the information within it (which isn't too far off from cold reality; just don't mistake it for state-of-the-art) and for the glimpse of what I remember as that fearful 70's-and-early-80's mentality, back when everyone - even grade school kids - knew, as incontrovertible fact, that we were going to get "A-bombed" eventually... that was just how the world was going to end, and it was going to happen in our lifetimes, and there was no way around it.
If you yourself aren't old enough to remember that dull never-ending fear, this snippet from the introduction should give you a haunting idea of what it was like: "Each generation is born, lives and dies. The A-bomb, if it comes, like any disaster, will prune human lives. Finally each of us must die. It is a question of timing."
Thank god for Glasnost, eh?
