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.

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.

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 bigger question again about how to do prevention. It's not simply about putting out the early warning. The early warning was put out on Abyei; everybody knew that this was coming. This was intentional, and still it happened. So this idea that we fail to stop these things because there's not awareness about them, or that we need better early warning information, I'm increasingly skeptical of. I think it's about how you move that information into the policy process.

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.

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.

When you are dealing with a mass movement, as opposed to a quote-unquote "elite," you are talking to people who don't have time to read long research papers. You have to communicate with them in sound bites, around every other thing they are doing. So it takes a long time to shift people from one message to the next, especially if your foundational narrative was, "The only one thing in the entire world you should be paying attention to is Darfur."
