Yes, tribalism is at the root of all group-on-group conflict. There are two governing ideologies to deal with this: collectivism and individualism. Collectivism attempts to unite the tribes, so to speak, while individualism seeks to shrink each tribe to a party of one. Obviously tribal warfare happens no matter what, but I think the historical record is pretty clear about which one has done a better job of minimizing it.
