I think most generations tend to learn the lesson of war the hard way. There is a deep attraction to the empowerment. Freud is right: societies either become locked in a collective embrace of Eros, as individuals do, or a collective embrace of Thanatos, the death instinct. They swing between the two. The notion that societies are naturally prone toward self-preservation is wrong. Self-annihilation can be deeply addictive, intoxicating, enticing. So I take a darker view of human nature, that war is probably always going to be with us. I think history bears me out.
