Me three.

Well, I think that *children* already understand it quite well:
just observe three year olds on a playground. But a very
easy-to-understand book does need to be written for college
Sophomores, and for the usual sort of leftists that go around
preaching unilateral disarmament and appeasement.

Yes, it may have been best for more people in more
universes if the U.S. had adopted Bertrand Russell's
suggestion and invaded the Soviet Union in 1947 to
preserve an atomic monopoly forever.

Yes, I agree if that is the definition of MAD. The real
cold war scenario gave no little advantage to he who struck
first, and the Soviet Union and the United States are to
be congratulated on their restraint. One imagine that if
certain other 20th century powers had been the first to
get nukes, they would have been used, and often.

The most interesting scenarios are those that start from
MAD and then slowly evolve towards

                 Cooperate Defect
Cooperate 1,1 -1000, 100
Defect 100, -1000 -100, -100

Yikes! It's like slowing raising the temperature in
a kettle holding a frog. Is one to be "hyper-rational"
and start the war immediately as soon as one realizes
that the evolution towards the latter table has started?
Or is one to grimly hang-on, hoping against hope that
either the evolution stops or the other party grimly
also hangs on?
