You have to simplify - there is no other way to reach a mass audience. And you have to feed them evidence of their own success to keep them motivated.

I think people felt like they did everything they had been told they should do to fix the problem, and it still wasn't fixed. Then you have these other parts of Sudan, [which] in actual fact have been left on the back burner for way too long, so there was this scramble, probably a year ago now, to focus on the fact that this peace agreement was basically falling apart.

Something I've learned over time, and trying to remind myself this week as I am back in New York and feeling pretty anxious, is that things always seem less dire when you're in the country than when you're outside. I don't exactly know why it is, except that people just have to get on with their life, so they do. And you don't have time to do anything other than keep going.

There's a huge misconception that it's all about the oil, and the truth is there's actually not much oil left in Abyei. The misperception arose because when the peace agreement was signed in 2005, Abyei accounted for a quarter of Sudan's oil production. Since then, the Permanent Court of Arbitration in The Hague defined major oil fields to lie outside Abyei. They're in the north now, not even up for grabs, and they account for one percent of the oil in Sudan. The idea that it's "oil-rich Abyei" is out of date.

I feel really uncomfortable writing about Sudan when I'm not there. It always looks different. When you're outside Sudan it's easy to lose sight of how much of what happens is driven by local politics. And when you're in America in particular, there's this sense that what D.C. has to say is the only thing that counts.

Strikingly consistent across all of the battles in Sudan's history has been a fundamental conflict over what are and what are not seen as legitimate aspects of Sudanese identity.

I try not to cover Sudan from afar. I feel really uncomfortable writing about Sudan when I'm not there. It always looks different. When you're outside Sudan it's easy to lose sight of how much of what happens is driven by local politics. And when you're in America in particular, there's this sense that what D.C. has to say is the only thing that counts. Unsurprisingly people in Sudan don't feel the same way.
