The south really wants Abyei; they have a core constituency who reside in the area who believe that Abyei belongs to the south. There are a number of those sons of Abyei in high positions of government in South Sudan, so it's pretty hard for South Sudan to just walk away.

During the civil war, the Sudanese government armed the Misseriya nomads as proxy. Even though both groups had coexisted quite well prior to the conflict, it all become much more difficult as a consequence.

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.

No question that the spotlight on Darfur has, for all intents and purposes, disappeared. And that's deeply problematic, because it hasn't disappeared because Darfur has been solved.

For sure I see so much in Sudan that is wonderful, normal life - young entrepreneurs starting up NGO projects, kids mucking around and being kids. Everything else that happens in normal life in any part of the world, and we never get that in our media coverage. We only talk about Sudan once it's in crisis, so we end up with a distorted sense of what daily life is like for a lot of people.

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.

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.
