Anthropologists observed decades ago that the more men and women are separated from each other, the more collectively aggressive -- warlike -- the culture is: think of Victorian England, the Zulus, and of course many Islamic cultures. Melvin Konner suggested over twenty years ago that the simplest way to reduce war is to mix men and women. Assuming that warfare is the only way to compete on the global stage is naive at best, considering that the US's dominance of the world is not through effective warfare (witness Vietnam, Korea, Iraq) but economics and cultural infiltration. Fukuyama has defined competition too narrowly -- and falsely.
