The continuing raids by Sudanese tribesmen have sent over 50,000 Chad civilians fleeing from their villages. Some of the Sudanese raiders belong to tribes with branches in Chad. Same thing with the victims. Like Sudan, Chad has tribes that consider themselves Arab, while others consider themselves just African. There has always been animosity between the two groups, although intermarriage, rape and slavery have resulted in both groups looking much alike, and sharing languages and customs.
Sudan continues to receive the support of other Arab nations, especially Egypt. The Arab nations oppose bringing in UN, and especially European, peacekeepers. This would offend the dignity of the Arab world (the way overthrowing Saddam Hussein did), thus the Arabs allow the ethnic cleansing of Darfur to continue, even though the victims are Moslem. These attacks are less painful to Arabs because the victims are black Africans, who have always been held in low esteem by Arabs, even if the Africans are Moslem. . . . a coalition of Arab and Moslem nations, plus China (which wants to protect its business interests in Sudan), block any too aggressive operations by the UN.
So much for “never again.” And for the U.N.
