The NYTimes story of Powell's trip to Darfur was frustrating to read since it feels like people are doing too little, too late. It must have been excruciating for him to know what's happening, see some of the victims, hear their stories and then have Sudanese government officials claim that the situation isn't as bad as reports say or flat out deny some aspects completely. There were even reports that some refugees were moved out of the camp before Powell's visit and replaced by fitter looking shills.
Over at Jim Moore's Journal, my preferred source for information about Sudan, there's a link to what he calls a must-read editorial in the Christian Science Monitor. It outlines steps the international community could take to stop the genocide and stabilize Darfur. There are probably a thousand problems with what they suggest, but it's the first time I've read a detailed and thoughtful list of suggestions to begin to address the imminent loss of hundreds of thousands of lives.
