Leaving aside discussions about the worth of UN resolutions, can somebody explain to me how a surprise attack on Iran will do anything other than a) turn every Shia in the entire world entirely against the United States for the rest of history, b) massively increase the instability of the region, driving oil prices up for everybody, c) drive the global development of non-state nuclear capacity further underground, and d) convince anybody that was thinking about developing nuclear capacity that their worries about American interventionism are entirely correct, and that the best approach will be to move to nuclear terrorism as quickly as possible?
