I have to say that we wish Canada would be a little bit more involved than your southern colleagues, or that your colleagues directly to the south would sometimes be a little less involved in some of these things, because their involvement is not always very helpful. I would have thought that Canada, with its particular history and circumstances, has quite a lot to offer the Sudanese people. I think examples are very useful of how states can work in a federation and a confederation and so on, but maybe the time for that has already passed.
One of the challenges in Abyei is the extent to which the Misseriya will feel that they've been sold out by the government. There have been Misseriya groups joining JEM, for example, in fighting the Riziegat, who are seen to be more pro-government, so there's a lot of tension there. It's not clear that the Misseriya will really feel that the government, the north, adequately represents them.
In terms of Canada's role, it's hard to know how best you can incentivize people to make the right decisions. None of this is particularly complicated if there were the political will to implement it.
