I guess this is off topic, but one thing I've always found when studying Sudan is that you can read so much (I did a report on it 2 years ago), and still come away not believing you have in anyway read anything objective or approximating the truth. There is so little reliable information coming out of it that it's hard to know what to believe. Would they be a serious oil producer? Is the war in the south still about the SPLM/A's original goals? etc. And above all, it's a tragedy that rarely gets mentioned, except perhaps by Christians still anxious to portray themselves as persecuted (the torture, murders, conscription of child soldiers, etc. goes very much both ways). I don't think anyone who's not been to Sudan themselves, and visited both the north and south, will be able to tell you much objectively about the place.
