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.

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 think fundamentally the bigger question is, what are we expecting peacekeepers to do? Are they actually, as the traditional conception would have it, keeping peace, in which case they're not there to actively intervene and stop violence? When we send them into these places, do we expect they will respond forcefully?

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.

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.

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.

Strikingly consistent across all of the battles in Sudan's history has been a fundamental conflict over what are and what are not seen as legitimate aspects of Sudanese identity.
