Sudan is a nation divided: its population in the north, where the majority resides, is culturally Arab, while the south shares the civilization of black Africa. Faced with this diversity, the government has embarked on a course of Islamization to unify Sudan. Although popular dissatisfaction with the Islamic state runs deep, Hassan al-Turabi, the charismatic Islamic leader, and his followers are so well entrenched that it may be impossible to get them out, even with elections.
