To Invade or Not to Invade?

This photo, released by the UN, displays a group of Sudanese people using a sign to display their frustration with "international forces" (more than likely the U.S. and other powerful countries). It is apparent that they are not satisfied with the lack help they have been receiving, however the leaders of Sudan continue refuse most of the help of most outside sources. With such a savage atmosphere, it is surely difficult to imagine what attempt could be made to remedy this civil war. I surely hope that the United States somehow turns their focus to this country in such desperate need.
