Imagine that you are a senior adviser to the Iranian supreme leader Ayatollah Ali Khamenei and have decided that sanctions and other pressures on Iran have accomplished exactly what they ostensibly are designed to do ( to the extent that any such presumed purpose of the pressure can be discerned from what is coming out of Washington ): to change minds among policy makers in Tehran about Iran's nuclear activities. You, the adviser, have concluded that the pressures are sufficiently damaging to Iranian interests that Iran ought to make whatever policy changes are needed to get the pressure to stop. What, exactly, do you advise your boss to do?
As you contemplate that question, you realize there are several conditions that would have to be met in order for any advice you gave not to be rejected immediately and categorically, if not by the supreme leader himself then by others in the regime who have a say in shaping policy. Whatever step you recommend would have to be politically feasible, which also means being psychologically feasible for the leader, for other Iranian policy makers and for the Iranian public. There also would have to be some mechanism for reaching an understanding or agreement with the Americans, given that ending the U.S.-led pressure would be the whole purpose of changing policy. Closely related to that last requirement, you would also need to point to good reason to believe that if Tehran did change policy, the United States would indeed end the pressure.
After carefully reflecting on all this, you would have to decide that—as long as the policies and discourse you hear coming from the United States remain as they are—the requirements cannot be met. The United States has made it almost impossible for Iran to say yes to whatever it is the United States is supposedly demanding of Iran. You quietly drop the idea of recommending to the supreme leader any change of policy.
One can, to be sure, imagine an Iranian statement that would sufficiently get U.S. attention that it would affect U.S. policies. Ayatollah Khamenei could go on television and say, “The pressure is too great. We need to change our ways. The centrifuges have been turned off, and we have begun dismantling them. We will take whatever other steps are needed to make the pressure stop.” Anything even remotely resembling such a “cry uncle” speech is out of the question. Even in the extremely unlikely event that the supreme leader ever considered doing anything like that, imagine what the response would be from the Iranian equivalents of Republican presidential candidates. There would screams of “appeasement” and outcries against “apologizing” to the Americans that would be loud enough to shake the foundations of the regime—which is part of the reason no such speech will be made. Or if you can't imagine that, imagine how a similar issue would play here if it were the United States that was being pressured by a foreign power.
A peaceful Iranian nuclear program—as Tehran contends that its program is—has broad and strong support among Iranians. Any feasible change in Iranian policies that could be the basis of a new understanding with the United States and the West would include a continuing Iranian nuclear program, very likely including the enrichment of uranium by Iran. The substance of any such understanding would involve technical details about inspections and safeguards. Such details would need to be negotiated. Feasible arrangements that would provide the minimum assurances to both sides could be negotiated, but they are unexplored. They remain unexplored because the United States has abandoned negotiations and has made its policy toward Iran solely one of pressure and sanctions.
Conceivably Iran could do some things unilaterally that might be interpreted as the sort of policy changes that the pressure ostensibly is designed to achieve. But if the recent past is any guide, Iranian decision makers would have no basis for believing that any such changes would register with the United States and be sufficiently accepted and favorably interpreted to lead to any easing of sanctions. Even when the U.S. intelligence community assessed that Iranian work on the design of nuclear devices had ceased, this only served to touch off a firestorm of controversy and accusations about political agendas. The United States has given Iranians every reason to believe that it is committed to nothing other than pressure and more pressure, regardless of what modifications Iran may make in its programs. Any Iranian adviser who suggested otherwise would be shouted down by his colleagues in Tehran.
There is sadly no prospect for this dynamic to change any time soon, with a U.S. political environment in which, as Ted Galen Carpenter aptly describes , diplomacy with anyone we don't happen to like is disparaged as appeasement. The House of Representatives has even passed legislation (which awaits action in the Senate in the new year) that—in one of the most astoundingly self-crippling moves a house of Congress has ever made—would prohibit any official contact with Iranians in the absence of a cumbersome presidential waiver procedure.
