They need an Ataturk or some other forward thinker who can grind the old tribalism under foot and usher in an age of reason and Weaternism.
It has long been my thought that there will be migration into Africa by the growing populations in Asia,specifically India.
Africa has wide open spaces and what seems to be a passive, less educable population that can be dominated by the middle class Indians. Indians are or seem to have no tradition of operations beyond their traditional tribal borders. It is my thought that the aggressive migration pressure will force the move into Africa.
That is essentially the same force now in process here with the pressure being exerted in the south. The same for Europe, the force coming from North Africa and the middle east.
