Wade is cautioning against sanctions on Mauritania. Senegal has been rather quiet since the onset of the coup. Mauritanian refugees who returned their country recently are now heading back to Senegal. Wade seems to fear the humanitarian costs of sanctions (which might spill over into his country). I have an idea of how the Mauritanians could use this and other means to undermine Algerian efforts to isolate them. Will post more on that and on Wade when I have more time.
