o 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.

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.

What's really interesting, though, is that some people in the Messirya are starting to see Darfuri rebels - so non-Arab, [from the] Justice and Equality Movement - have moved over into Southern Kordofan, which is supposed to be a Messirya stronghold, and started recruiting Messirya to go and fight against the Khartoum government in Darfur. Just another example of how everything in Sudan is interlinked.

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.

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.

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.
