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.

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 The idea that it's "oil-rich Abyei" is out of date.

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.

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."

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.

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.
