The alarmism about the prospect of Iran developing a nuclear weapon is unmatched by any comparably intense attention to exactly why such a possibility is supposedly so dire. Among the voluminous opinion pieces, panel discussions, campaign rhetoric, and miscellaneous outcries on facets of this subject, one could search in vain for any detailed analysis of just what difference the advent of an Iranian nuke would make. Most of the discourse on the topic simply seems to take as a given, not needing any analysis, that an Iranian nuclear weapon would be so bad that to prevent it warrants considering even extreme measures.
Recently Ash Jain of the Washington Institute for Near East Policy produced what appears to fill this gap. His monograph, titled “Nuclear Weapons and Iran's Global Ambitions: Troubling Scenarios,” is, at least on the face of it, a serious effort to analyze the regional and global consequences of Iranian nuclear weapons. It is the most extensive consideration of this question I have seen from anyone who clearly believes that an Iranian nuke would be very bad. As such, Jain deserves credit for taking this stab at the subject. As a serious, extensive effort, his paper can be taken as demonstrating the limits of any case about the dangers of Iranian nuclear weapons.
Jain begins by stacking the deck in describing the Iranian objectives that presumably would underlie any use to which the Iranians would put a nuclear capability. Nuclear weapons in the hands of a “pragmatic regime” driven primarily by “a desire to protect and deter outside attack” would be far different, he says, from their possession by an “ideological regime,” which is the label he pins on Iran. This is consistent with much of the alarmist rhetoric, which depicts the Iranian regime as somehow fundamentally different from most governments in how it thinks and operates and what it aspires to. But what exactly defines an “ideological regime” and distinguishes it from a “pragmatic regime”? There is plenty of ideology floating around, some of which has significant implications for foreign policy and international security, and the more one thinks about it, the more one realizes that the regime in Tehran isn't so different after all. This example ought to be too obvious to need pointing out, but we recently had a government right here in Washington that got so influenced by an ideology (in this case, the neoconservative kind) that it launched a major offensive war of choice thousands of miles away, at much cost and misery to the United States. Is this what Jain means by an “ideological regime”?
Jain allows that “some analysts” see the Iranian regime, like many other regimes, concerned with its own survival and with deterring and preventing hostile actions from those who have given it good reason to be perceived as threats—in this case, Israel or the United States. Then he dismisses this view in a single sentence as “inconsistent not only with Iranian activities on the ground but with the longstanding public statements of its own leaders.” But he never actually addresses the record of Iranian activities on the ground. That record in fact shows a lot of pragmatism and even caution. Jain does go on to quote at length the public statements of Iranian leaders—to depict an Iran driven by revolutionary and aggressive objectives—but does not weigh any of this rhetoric against the fundamental interests of defense and survival. He also does not distinguish between what is merely rhetoric or political blather for domestic or international purposes and what represents genuine, active objectives of the Islamic Republic.
