A draft would be good, I think, because it would soon arouse such a degree of protest from the general American public (now that it was affecting more of them directly) that the war would become insupportable for any administration to pursue for much longer. Therefore, I hope they institute a new draft ASAP.
One question, Ron. Why would the fall of the Maliki government necessarily mean the departure of American occupying forces? Going by the Vietnam record (Diem, Thieu and all the others) cannot the fall of one useless semi-puppet government in an American satellite state simply lead to the rapid creation of another in its place? I think they would probably come up with something. At least they would certainly try to. Maybe they could import one of the Saudi Bin Ladens (You know? The good ones?) to head it.
