Josh and Robert both question whether we will engage in regime change in Iran or just do the special forces equivalent of Israel’s 1981 air strike that took out the nuclear reactor at Osiraq in Iraq thereby preventing Saddam from obtaining Nukes. I’d like to believe that we could do a quiet destruction operation that would embarass Iran enough so they wouldn’t talk about it, but I don’t think such an operation is actually plausible. I think we don’t have the on the ground intelligence to know everything we need to know to make such an operation a success. The only real defense here is regime change (which is why I suspect US governemnet officials are making such strong denials of Hersh’s claims).
I suspect the operation is a combination of clandestine attacks and much more loud “tear down this wall” style rhetoric against the Iranian regime. As the regime starts to fall, I can imagine special forces disrupting its attempts to maintain order.
As for Josh’s question about the draft, it makes little sense. People in favor of these sorts of military action believe that it is better to attack now than to attack later when more forces will be required and when more civilian lives would be at risk (e.g. from WMD). The draft question can go in either direction depending on what you believe the merits of the military action to be. As an aside, people in favor or high taxes and regulations are more likely to favor the draft than free marketers who believe people should be free to decide whether to join the military.
