NPR - Sudan Sanctions

I might be injecting a little too much of my own beliefs here, but what positive effects will increasing sanctions on an already impoverished country bring about? I don't know what Bush is doing here. He hopes that cutting economic ties with Sudan over the Darfur crisis will nudge the current regime away from... hmm... genocide. Right. I don't think that cutting funds will really have an impact on something so hateful. There has to be another solution.
