The conflict in South Sudan, as approached through Agreement on Resolution of Conflict in South Sudan (ARCSS) and current Revitalization talks, faces several challenges key among them being ceasefire agreement violations, politico-military complex, ethnic factor, weak peace support mechanism, and lack of political will. This brief recommends implementation of transitional justice, strengthening of peace support mechanisms, integration and regularization of armies, diplomatic lobbying for common position on South Sudan, and elimination of military option to the conflict for the success of ARCSS.
