Perhaps in these days of nuclear weapons, cooperation would be a better survival technique than aggression.
I agree with you, cooperation is always better survival technique, but in general humans aren't very capable of such rationalization. We are still bound by our Monkeyspheres, where we need to group up with some people versus the others, and then respond with aggression against them just because they don't belong in our group. No matter what advancement human society has gone through, we are still very tribal species, who will practice collaboration within our group, and aggression against other groups.
