As the UN decides to push more troops into the country, we ask if it can save the world's newest nation from collapse. To discuss this, Inside Story presenter Folly Bah Thibault is joined by guests: Choul Laam, the chief of staff for the secretary general of the ruling Sudan People's Liberation Movement; Douglas Johnson who has written several books on South Sudan including The Root Causes of Sudan's Civil Wars; and Rebecca Garang, an adviser to the president of South Sudan, Salva Kiir, and the widow of John Garang, who was the chairman of the SPLM, the rebel movement that signed a peace deal with the Sudanese government in 2005 - a deal that eventually led to South Sudan's independence.
