It is here that we get to the heart of the issue. While from a rational perspective the Iranians would be fools to launch such an attack, the Israeli position is that the Iranians are not rational actors and that their religious fanaticism makes any attempt to predict their actions pointless. Thus, the Iranians might well accept the annihilation of their country in order to destroy Israel in a sort of megasuicide bombing. The Israelis point to the Iranians' rhetoric as evidence of their fanaticism. Yet, as we know, political rhetoric is not always politically predictive. In addition, rhetoric aside, Iran has pursued a cautious foreign policy, pursuing its ends with covert rather than overt means. It has rarely taken reckless action, engaging instead in reckless rhetoric.
If the Israelis believe the Iranians are not deterred by the prospect of mutually assured destruction, then allowing them to develop nuclear weapons would be irrational. If they do see the Iranians as rational actors, then shaping the psychological environment in which Iran acquires nuclear weapons is a critical element of mutually assured destruction. Herein lies the root of the great Israeli debate that pits the Netanyahu government, which appears to regard Iran as irrational, against significant segments of the Israeli military and intelligence communities, which regard Iran as rational.
Avoiding Attaining a Weapon
Assuming the Iranians are rational actors, their optimal strategy lies not in acquiring nuclear weapons and certainly not in using them, but instead in having a credible weapons development program that permits them to be seen as significant international actors. Developing weapons without ever producing them gives Iran international political significance, albeit at the cost of sanctions of debatable impact. At the same time, it does not force anyone to act against them, thereby permitting outsiders to avoid incurring the uncertainties and risks of such action.
Up to this point, the Iranians have not even fielded a device for testing, let alone a deliverable weapon. For all their activity, either their technical limitations or a political decision has kept them from actually crossing the obvious redlines and left Israel trying to define some developmental redline.
Iran's approach has created a slowly unfolding crisis, reinforced by Israel's slowly rolling response. For its part, all of Israel's rhetoric -- and periodic threats of imminent attack -- has been going on for several years, but the Israelis have done little beyond some covert and cyberattacks to block the Iranian nuclear program. Just as the gap between Iranian rhetoric and action has been telling, so, too, has the gap between Israeli rhetoric and reality. Both want to appear more fearsome than either is actually willing to act.
