"The United States has historically played a major role in supporting peace and stability for the country, which gained its independence from Sudan in 2011 after a long civil war between the Sudanese government and southern insurgents. Congress has been a key actor in setting U.S. policy toward both Sudans and supporting South Sudanese independence. As such, the Obama Administration and Congress face a series of complex questions as they seek to convince rival South Sudanese leaders to cease hostilities, reengage in political dialogue, and prevent further humanitarian suffering. The future of what successive U.S. Administrations have considered to be an important relationship with South Sudanese leaders is also in question." (thanks Regan)
