So I was reading about all the remote-controlled "robot" predator drones flying around in Afghanistan and wherever, and it occurred to me that it would be a good story if an altruistic arms manufacturer started selling superior robotic war machines. Of course, eventually all the major powers would be fighting their battles "by wire", and after some years it would be revealed at the end of the story that all battles currently being fought were in fact being fought virtually with no actual presence in the real world.

Someone more talented than me has no doubt already written such a story.
