Special comment: For reasons that are not clear, many of the governments in Sub-Saharan Africa have been destabilized a year or so after the catastrophe of the Arab Spring uprisings. Countries in stress include Mauritania, Mali, Niger, Central African Republic, Nigeria, Congo Brazzaville, Congo Kinshasa, South Sudan and Somalia. These readily come to mind, but there are others, no doubt.
Sub-Saharan African has not experienced this extent of violent internal unrest since 1960.
