The precarious peace between northern and southern Sudan stands at a crucial crossroads. Intended by its architects as the cornerstone of peace in a country fractured by conflict, the Comprehensive Peace Agreement, or CPA, has been hamstrung by the National Congress Party's intransigence, the Sudan People's Liberation Movement's growing pains, and the international community's neglect. With two years remaining before a referendum on self-determination for the south, confidence in the CPA is diminishing, mistrust between the parties is mounting, and both sides are arming in preparation for a resumption of hostilities. The International Criminal Court's forthcoming arrest warrant against Sudanese President Omar al-Bashir will further isolate the NCP and adds an additional layer of uncertainty to the CPA's fate.
