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."

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.

Southern Kordofan is not a disputed territory. It is, and will remain, in the north, where the Nuba Mountains are. People believe there was a genocide there in 1990s. The Nuba, who are northerners, fought with the south in the north-south war. But they have their own individual interests, and they will remain in the north after the south splits.

It's best to think of these as two things - they're related, but there's different dynamics going on with each of them. A key difference is Abyei is contested territory. We still do not know whether Abyei is going to belong to the new country of South Sudan or effectively the new country of Sudan, the northern part. That was supposed to be decided by a referendum in January; that referendum never happened, so it was being dealt with through political negotiations.

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.

Every indication is that the Sudanese government will be defining it as an Arab, Muslim country. But there are also a lot of Christians and a lot of people, like the Nuba, who are not Arab. And that is why it is going to be problematic that Sudan will be defined in this 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.
