I am sorry to say that war will never stop. You know how when you have a small child, the child will play with another child. Then you can throw in one toy and they will fight over it. Humans as a whole are greedy hateful bastards and nothing can change that. You say you dont want war but I be deep down if someone gave you a present and someone else took it away you would be pissed enough to start slapping/hitting/killing people. I dont think we will ever figure out our emotions or stop fighting.
