"[O]n the African continent, a resurgence of human slavery has occurred in Sudan. In this zealously Islamic nation, black Christians have been enslaved by the thousands, largely by Baggara Arab Muslims. … [W]hat would it take to abolish slavery in Sudan? There is no principle of individual rights in the nation’s history–and Islam, the dominant religion, permits slavery of non-Muslims."
