For a good summary of the situation concerning the activities of the so-called White Army, recently revived by a group of Lou-Nuer youths, in Jonglei State of South Sudan, see the 22 February 2012 piece titled South Sudan Officials Rebuff the White Army Comeback by Annette LaRocco and Nenad Marinkovic on the Enough Project website.
The authors conclude that the inter-communal violence in South Sudan is a very real issue that threatens to erode the fragile social and political stability of this new nation.
