My latest column in the Bulletin is all about Iran sanctions: what they’re good for and why they’re so hard to get (not necessarily in that order). Go on, go read it; I’ll bet you’ll never guess what Roswell Gilpatric & Co. have to do with the story.

But to make a long story short, the question of a nuclear-armed Iran just isn’t so close to home for the Russians and the Chinese, compared to the West. That’s why we’ve had moments like this one.

Evidence for this conclusion can be found not only in the statements and actions of leaders, but also in public opinion, which I think provides a decent approximation of elite perceptions of the outside world in most countries, even non-democratic ones.

Surveys conducted in the spring of 2007 by the Pew Global Attitudes Project showed 93% of Americans opposing the idea of Iran with nuclear weapons, alongside 80% of Russians and 69% of Chinese. Even more strikingly, 59% of Americans saw a nuclear-armed Iran as a “very serious” threat to their own country, compared to just 34% of Russians and 15% of Chinese. Their hearts just aren’t in it.

Still, we’re pretty close to a fourth round of sanctions now. Which is probably why the Iranians and the Russians have started snarling at each other.

(More about the surveys: the Pewsters found that a gulf separates the perceptions of most Westerners, Sunni Arabs, Christian Arabs, and Israelis — all of whom tend to worry about Iran’s nuclear-weapons potential — from those of Asian and African Muslims, who tend to be supportive. Pakistanis are downright enthusiastic. Shi’ite Arabs and Palestinians also appear very comfortable with the idea of an Iranian bomb.)

A Letter Thrown Over the Transom

But that’s just an interesting aside. What I want to know is, can we do sanctions and diplomacy with Iran at the same time? Or must diplomacy wait until later?

The view of the Obama administration, expressed again recently in a conference call with three Senior Administration Officials, is that you can’t do nuclear diplomacy with Iran if the Iranians won’t sit down and talk to you about their nuclear program. This has a certain elegance and simplicity.

But then there’s the view of the Brazilians and Turks, which is, if the Iranians can be induced to negotiate even at a great remove from their negotiating partners, that ought to be good enough, especially if the results line up with the terms expressed by President Obama in an April 20 letter to Brazilian President Lula — which was subsequently leaked to a Brazilian publication. Which must be one of the most astonishing acts of international diplomatic petulance of our times. But that’s neither here nor there.

(On that conference call last week, Senior Official Number Two was reduced to a somewhat convoluted explanation of why the April 20 letter failed to mention the importance of not enriching uranium to nearly 20% if you have no reason to. If he’d been thinking on his feet, perhaps he would have recalled that this point was mentioned in the Feb. 12 letter from France, Russia, and the United States to the IAEA.)

Are the Brazilians right? Should the U.S. and its partners just swallow hard and take the offer as it is?

The Two-Track Policy We Have

Don Rumsfeld once told a bellyacher, “As you know, you go to war with the army you have, not the army you might want or wish to have at a later time.” So it is, perhaps, with two-track policies. As our friend A2 points out, the deal may not do much concretely, but it sets useful precedents, and nothing in it actually leaves us worse off. So why not pass the sanctions resolution and immediately announce that we’re taking the Iranians up on their version of the deal? If the Iranians back out, then they back out.

That’s been the conclusion of many a wonk this week: George Perkovich, for one. And then there’s an odd-bedfellows list that includes several notable nonproliferation wonks, including ACW’s own Jeff Lewis. (They’re for the taking up the Zombie Fuel Swap, but don’t mention the sanctions resolution one way or the other.)

This is not an easy call. Through their IAEA ambassador, the Iranians have finally clarified their position on unnecessary enrichment to nearly 20%, and their position is now that it’s necessary. (Contrast this with their position in February.) It appears from the latest IAEA report that they plan to build out six cascades at PFEP for this purpose.

Daryl Kimball, for one, thinks we need to nail down the 20% business, much as Barzashka and Oelrich were thinking back in April. But this will be hard to do without actual negotiations. And at this point, the Iranians are insisting on negotiating by press conference only. It’s probably safe to conclude that the Brazilian channel has broken down. Irreconcilable differences, you might say.

Perhaps, once the next Security Council Resolution has been safely passed, it will be time to take what there is to take, and then see if it leads anywhere.
