Just recently I listened to the old radio show X Minus One's adaptation of Philip K Dick's short story, "The Defenders" which is appropriate to this story. In the story a brief nuclear war forces nearly everyone on the planet to live underground while robots continue the fight and the nuclear bombardment on the surface. Unknown to the humans, the robots figured out early on that the war was really stupid, so they stopped fighting and began to repair and renew the world, all the while sending fake war reports back to the humans and telling them that the radiation levels were toxic, when in fact there was no radiation left. Very interesting story.
Here's hoping that if every nation and group in the world starts making robots to fight for us, maybe the robots will realize how stupid this all is and refuse to listen to us until we all come to our senses.
