In this paper Francis Mading Deng reflects on international cooperation in South Sudan. He writes: It is now widely recognized that there is an increasing call for regional and international action to end the current crisis in South Sudan. This is a crisis that has inflicted and continues to inflict on the people untold suffering, death, and destruction. Resisting regional and international involvement cannot be in the interest of the Government and people of South Sudan. Nor is it advisable for regional and international actors to take unilateral measures against the will of the Government and people of South Sudan. That would entail a confrontation that would only complicate and aggravate matters, with no real winners. What is needed is a partnership between the Government and the international community to join hands and strengthen collective capacity and ability to bring a speedy end to the suffering of the people and the devastation of the country.
