situation in south sudan

when people learn that I study genocide, a question that is often asked is how can genocide be prevented? there are lots of smart people who are working on this question. many recognize that foolproof ways of always preventing mass killings is not possible. but it seems that there are signs that mass violence will break out, that civilians may be caught in conflict. it is these signs that need greater attention and immediate action. this kristof story on south sudan strikes me as one of those cases. maybe all of the attention that has been given to darfur can be used to render action in the southern part of sudan.
