No, we haven't evolved past major wars, but nuclear weapons have made them impossible to win. That is something new under the sun. That's why I don't believe in "a world without nuclear weapons" - a world without nuclear weapons is a world in which the next world war is imminent. That said, something is going to happen in the south China sea. But no rational actor would ever start a nuclear war. That leaves cold-war style local dominance battles. Not nice, but not a major war either.
