The minute the US goes there, the whole world will say it's another case of the US imposing its will by force. The rapists will suddenly become poor Muslims who are being killed by the bloodthirsty US. Both the Darfur refugees and and their attackers will begin attacking the US. We'll also permit a large number of them to immigrate to the US where they'll promptly go on welfare, continue to have a dozen children each, and demand more services.
No thanks; let them sort it out themselves. After all Sudan is controlled by Muslims and we all know they are peaceful people.
