Back in the early 80s, I recall a discussion I had with my former biology teacher about the nuclear arms race. The nuclear freeze movement was picking up steam in Europe and making the news. Growing up, I never really expected to survive to adulthood, let alone get old. The Boomers had survival drills. By the time Gen X came along, the adults had stopped pretending that there was any chance of survival so we didn't waste time on drills. Anyway, my former biology teacher made the comment that he wasn't worried at all about nuclear war because no government would be willing to risk even one city let alone full MAD. No government would stand after losing a city. Years later, I learned that his thinking was also the prevailing belief in both the American and Soviet leadership during that period, other than within the Paul Nitze/Paul Wolfowitz/Dick Cheney clique. The nuclear arms race was about just about everything except deterrence.
