While popular uprisings in the Middle East have captured the lion's share of media attention in recent months, Iran's march to a military nuclear capability continues, as reflected in the latest IAEA report on Iran, released last week. As strange as this may sound, the foremost danger of Iran ultimately crossing the threshold and becoming a nuclear state is not the prospect that it will act irrationally in this new status. Irrationality would imply that Iran could at some point break the rules of mutual deterrence by launching a nuclear strike without regard for the anticipated reaction. In fact, the probability of this happening is quite low. Rather, the more immediate danger of a nuclear Iran lies in the extreme rationality that it is most likely to display in its actions vis-a-vis the region.
