The counter-argument is this: Iran’s regime is irrational and wants to destroy Israel even if the resulting counterattack would kill millions of Iranians and wreck the country. Yet while that analysis should not be totally ruled out, it is far from a certainty. Tehran is seeking nuclear weapons to make itself invulnerable to the costs of its non-nuclear subversion and support for terrorist and revolutionary forces. And a lot of what the Iranian leadership says is demagoguery to build support for itself at home, and to convince the masses to ignore its incompetence and mismanagement…

At the same time, a new theme in the America mass media–for example here and here–is that the United States is headed toward war with Iran either by electing a Republican president, the inevitable weight of events, or through having sanctions so effective that a cornered Iran will attack. The fact is that neither country wants to have an armed conflict and such a battle is easily avoidable. Ironically, those who claim Iran is going to attack are using the crazy Tehran regime concept that they reject when it comes to nuclear weapons. And the “watch out for the warmongering Republicans slogan” is part of the election campaign…

But here’s what’s most likely going to happen: Iran will get nuclear weapons. Iran is not going to stop its nuclear drive (though it could stop short of actually building bombs or warheads ready to go). Western policies are not so bold or adventurous as to go to war; Israel’s interests and capabilities do not make attacking sensible. An attack would not solve but increase problems. And no matter how crazy you think Iran’s regime is, the inescapable predicable threat is not high enough to force policymakers to risk getting hundreds of thousands, perhaps millions of people killed, when the chance of avoiding such an outcome is very high.
