Do the States of today not "prey upon one another," only on a thousand times bigger and more vicious scale?

Nothing I have read suggests huge loss of life in "primitive tribal disputes" on the scale of modern warfare, with new super weapons being developed to facilitate the slaughter.

Observations of "primitive dispute" have shown that,as in the animal kingdom, posturing and ritual plays a huge part.
I have also read that these tribes usually have a very good form of "local govt"....committee's of tribal elders etc, which can stop territorial disputes from getting out of hand.

It is only when we start re-organising tribalism in our own distorted image that things start to go wrong.
