I've just browsing the Net to find more information on Darfur for my Judaism class, which will be discussing Jewish responses to the genocide in Darfur this week (last week we discussed Elie Wiesel's Night and in both sections had very rich discussions that touched on contemporary issues as well). The United States has spent about $588 million since 2003 on Darfur. According to a report from USAID, we have given money to CARE, the World Food Program, the International Rescue Committee, and other groups for many different needs - for food security, health, shelter, management of refugee camps, emergency relief supplies, environmental protection (water safety), etc. The USAID information can be found at USAID: Sudan: Darfur Humanitarian Emergency. The latest report can be download in PDF format.
