"War, what is it good for? Absolutely Nothing."
"War takes away the easy supply of daily wants, and so proves a rough master, that brings most men's characters to a level with their fortunes..." Thuycidides
"Robbery is perhaps the oldest of labor-saving devices, and war vies with magic in its efforts to get something for nothing." (Mumford)
"Marriage is to the woman what war is to the man." J.P. Vernant.
In foraging societies men go to war to get or keep women. Access to women is the limiting factor on male's reproductive success. The most common spoils of tribal warfare are women. Raiders kill the men, abduct the nubile women, gang-rape them, and allocate them as wives. Leaders may sometimes use rape as a terror tactic to attain other ends, but it is effective precisely because the soldiers are so eager to implement it. In fact, it often backfires by giving the defenders an incalculable incentive to fight on, and probably for that reason, more than out of compassion for enemy women, modern armies have outlawed rape.

"War is not the opposite of peace."
