To discuss this, Inside Story presenter Fauzia Ibrahim is joined by guests: Barnaba Marial Benjamin, the minister of Foreign Affairs of South Sudan; Choul Laam, the chief of staff to the secretary general of the SPLM, that's short for Sudan People's Liberation Movement; and Aly Verjee, a senior researcher at the Rift Valley Institute in Doha.
