There is a MAJOR flaw in Huntington's postion , which I haven't seen anyone mention. Africa will NOT fight the rest of the world. There are too many, and far too diverse countries , for AFRICA, as a whole to do that. How can Egypt be a part of a coalition with Zimbabwe and Nigeria ? Perhaps some SubSharan countries could possibly coaless; however , so many countries there are sliding into Stone Age tribalism, that the blood hatreds between tribes there, would preclude fighting the rest of the world.
I also think that he is wrong about Russia.
