You know, they have 20,000 centrifuges right now. If you are rolling them back to, say, 1,000, then you put them back a couple of years, and then you add — if you have very extensive verification means and I would like to see much like what we had in Iraq. If you have that then you’d have a high level of confidence if they tried to cheat you could catch them and you have plenty of time to do something about it. And I would suggest if you had that kind of a deal we should work out with the Israelis very soon before such a deal what would be the consequences if you caught them cheating, and agree on what those would be. That puts you in a very different place. Right now even that deal isn’t in the offing, because Iran doesn’t want to roll back their program. They want to roll back the sanctions, but they don’t want to roll back their program. They say we have peaceful intent … We have peaceful intent, and all you need to do is have some verification here to see it. Well, this is a country that has basically violated all of its obligations under the nuclear nonproliferation treaty for a long time, so there’s no reason to accept the peaceful intent. There’s a very important reason to impose the set of verification requirements on them that are extensive and give the world a little of confidence they don’t have today. . . .The only way [a deal] happens in my mind is if the Iranians come to the conclusion that they have much more to lose from – of diplomacy than we do.
