This effort provided support and analysis to a joint and interagency wargame on potential internal conflict in South Sudan. The analysis consisted of three parts: 1) Creating a database of violent incidents in South Sudan between 1997 and April 2011; 2) Creating and conducting a tabletop wargame to estimate the scale and cost of internal conflict in South Sudan; 3) Reporting the results of the wargame to an interagency conference on the “cost of conflict” in South Sudan.
