You know I have suggested in the past that Israel should train a militia of the Sudanese who enter our border illegally. They could help us fight the Arabs and eventually be shipped armed and ready to take back their own country from the Arab murderers.
Also I can think on yet another example of blacks defeating an invading Arab army- The Chadians defeated the invading Libyans in the 1980s, even though Libya had better equipment (Libyan armor was beaten by light, unarmored, Chadian "technicals").
