The combination of Iranian aggressiveness and Western diffidence has consequences for how a containment strategy would play out against a nuclear Iran. Behavior, after all, is largely a function of experience: why would a nuclear Iran, emboldened after successfully defying years of Western threats and sanctions, believe that the U.S. was seriously prepared to enforce this or that red line for the sake of containment? More likely, the U.S. would be at continual pains trying to restrain its allies, Israel above all, from responding too forcefully against Iranian provocations, lest they “destabilize” the region.
Consider also the red lines that Lindsay and Takeyh say would be essential for a policy of containment to work. Washington, they believe, would have to “publicly pledge to retaliate by any means it chooses if Iran used nuclear weapons against Israel”; it would have to tell Tehran that it “would strike preemptively, with whatever means it deems necessary, if Iran ever placed its nuclear forces on alert”; and it “should hold Tehran responsible for any nuclear transfer, whether authorized or not.”
Merely to list these conditions underscores the risks the U.S. would be required to run to enforce a containment policy. And given its habits of provocation, Iran would almost certainly be inclined to test America’s mettle at the earliest opportunity, probably by finding ambiguous ways to transgress America’s red lines. What would the U.S. do, for instance, if Iran found ways to transfer components of a nuclear program, perhaps of a dual-use variety, to Syria? Would that suffice as a casus belliagainst a nuclear Iran as far as the Obama administration was concerned? Or, as so often has been the case in the past, would the administration be content to express “grave concern” and perhaps refer the matter to the International Atomic Energy Agency?
One might also ask why Iran shouldn’t consider making wholesale nuclear-technology transfers to other parties if that suited its needs….
