(The emphasis is deliberate. This deterrent is more efficient since in most practical cases deterrents destroy populations—not decision makers.) - Herman Kahn

The next picture is a Goliath with four arms, reading a book, lofting a 1000-pound dumbbell, aiming a pistol at a target, painting a picture. The enemy can do everything. "He's a giant, seven feet tall with four arms, each with two biceps. Each arm can, of course, be used simultaneously."

I use the words "unauthorized behavior" rather than "accident" because we must guard against many types of events— psychopathic or irrational individuals, mechanical or human failure, sabotage, irresponsible behavior, and so on.

The final outcome of benevolent, informed, and intelligent decisions may turn out to be disastrous. But choices must be made; dies must be cast.
