In all these countries, our military aid is combined with civilian development assistance. This is the global war on terrorism as preventive rather than as proscriptive. It doesn't cost much. You could spread Green Beret teams across Africa for the price of one F-22 jet. If there is another model out there that will keep the U.S. military engaged without overextending it, and will help move along inter-agency cooperation, I have not seen it.
An interesting commentary.
