peace is in essence tolerance of people different from ourselves, tolerance of things we that do not agree with. historically, one of the key reasons tribes did not go to war as much as they might have is the fact that possible mutual destruction would have been much worse than tolerating each other. thus, the game theory outcome that might not give us the absolute best outcome, but it doesn't give us the worst outcome either.
doesn't war (the extreme form of competition) bring about change and improvement, at the expense of some pain and suffering?
isn't some force necessary to bring about peace?
whose peace? peace for the powerful?
