HARDtalk’s Shaun Ley speaks to Majak D’Agoôt, former deputy Defence Minister of South Sudan. It took half a century of civil war to give South Sudan its independence. Just five years later, leading figures from the independence struggle are calling for the UN to take charge. Majak D’Agoôt fought in the war of independence, became deputy minister of defence, but was sacked by the President and is now in exile. Have South Sudan's politicians failed their starving, displaced people or was the South never viable as a separate country in the first place?
