It's not a slaughter. The Muslims only rape women there and those who come from Dar Fur.
Ironically I met a whole group of young adults that were Nueri Sudanese a few years back. I sat for several hours with them and listen to their stories of how they escaped the slaughtering that was going on in their villages. They pleaded for help to reach Obummer to request help because their people were being slaughtered. These particular ones that I was blessed to be able to hear their stories were saved by Christian missionaries at the refugee camps.
For the US to invade there will have to be corporate interests in the region, resources, market expansion, something. The altruism shtick is required for any compliance on the part of the unsubstantial people.
