Oh damn, still in this dream.

People tend to forget humans are animals. You can rationalize and theorize all you want, but the matter still boils down to that. Despite our higher intelligence and the fact we, as a race have developed wondrous breakthroughs in technology and making incredible tools, we are still animals. We still rut, fight over mates, attack those who threaten our young, and do all of the same things as the rest of the animal kingdom. The fact there are overpopulation problems all over the world means we'll degenerate into tribal warfare. The middle east situation is nothing more than that. People fighting over beliefs, food, space to live, and structures that hold religious value. That won't change, because deep down, each and every one of those people is still tied to their animal instincts, which includes the need to prove dominance of themselves and the group they are living in. Not unless all but one group is wiped out. In which case, the cycle will simply renew itself when the group is forced to splinter off for whatever reasons it needs to do so.
