I don't mean to cut you off, but my time is limited.
You mentioned something at the outset of your answer, the fact that South Sudan is a very new country. It's unfair to you because it's a question that would require more time, but it still should be asked.
In such a new country, the institutions are just emerging. Think back, quite apart from the experience in South Sudan, or in Africa, for that matter. Think about the French experience. The French Revolution happens; there's a period of democracy and hope, and then all of a sudden, France falls into a period of outright dictatorship and enormous bloodshed. Then it reverts to democracy, and back to dictatorship, and so on and so forth. You don't have real democracy there until the mid-20th century.
Can you speak about the importance of institutions and those institutions coming into being, crystallizing, and really, the way that serves as a prerequisite for peace in the long term?
