How can there be peace?

Peace is something this world hasn't experienced since man first came into existence. Ancient tribes fighting for hunting grounds or reasons like that. Kingdoms in the Dark Ages fighting to gain more land and wealth, but also to survive. Peace is something everyone is after, even if they do not know it. Kim Jon Ung (sorry if I misspelled his name) is fighting for control of the world, like most other nations who have started wars in the past and are trying to do now. By controlling the world, they bring about peace, thus they are fighting for peace. But for us,peace is separate nations with many peace treaties, one for each nation. But peace is just where there are no nations threatening each other. But since peace should be comprised of many nations, it seems impossible for it to occur. Like Germany. It was our ally until Adolph Hitler took control and fought with the axis. There will eventually be someone who cannot stand all these nations and try to take over the world once more. This will make nations uneasy and ruining and trust there is between all nations. Peace will only occur if our species as a whole matures and we get over these desires for world dominance.
