So basically... http://en.wikipedia.org/wiki/The_Butter_Battle_Book
If this is truly all the human race is capable of; living in a perpetual stalemate of attack-power then we should just stay on our earth and perish.
Game theory is used for evolution too, so you're a creationist?
A longer answer would be along the lines of:
Humans have a wide range of possible behaviours, the trick is to organize society so we get a "nice" place (i.e. it is not "paying" to be non-"nice", please note quotes for complex PhD thesis definitions). If you're not able to see the world, your decision will have harmful effects according to your own morals. In short, your absolute moral judgements is a problem as much as Putin...
(I just wish that there were some way of educating away moral condemnation of people which refuse to understand stuff which goes against their ideology.)
Knowing idealists, in some generations people like you will want to genetically modify people to follow your morals -- Socialist "new human" style. We know how that goes, not only from science fiction.
But I already wrote an answer and got a non sequitur.
I pointed out that without rule of law, societies generally becomes clan societies. Out of pure game theory. And discussed why and how we know to avoid that.
You quote part of my description of clan societies -- and condemned humanity.
If you're not a teenager, that is too stupid to be anything but bad trolling.
