Depleted Uranium Munitions: I am, in the main, clueless about war, weaponry, etc. However, am I wrong to find this horrifying? And the fact that it seems little known (at least by our citizenry--including many of our elected officials) is even more troubling. Why do we never ask ethical questions about these things?... Has Rahm Emanuel's brother weighed in on the bioethics of using these DU weapons?
