Very interesting reads....I personally am of the mind that it is all about the oil and the money. Warring tribal factions still exist sadly enough.....history is littered with marauding bands and their atrocities. Set them in motion and have them sitting on a resource like black gold and yes....follow the dollar...you got a problem.
As an aside I always thought the king of the north would end up being the Islamic groups and south Christendom.... The hidden reserves, the oil the north rules over.....Isaac vs Ishmael.
If only intelligence, compassion and ethical behaviors could prevail....
