Selig Harrison's explanation of what the Iranians will actually demand in order to shut down nuclear enrichment seems about right. Problematically, I highly doubt that this administration -- or the next -- will give Iran enough in the way of incentives and security guarantees to shut down their nuclear program. Indeed, I think it's almost totally unlikely that they will pressure Israel to freeze their Dimona Reactor, though that sort of concession would finally give Iran the political breathing room to back down from their weaponization plans.
At the end of the day, I don't think we're going to stop the Iranian nuclear program. We're not serious enough about doing so. The country's politicians have committed to it going away, not trading it away. But the former isn't much of an option and the latter is unlikely. So it will likely proceed apace. That's why I'm so insistent on politicians actually signaling whether or not they'd attack Iran to end their atomic pursuit -- because that will probably be the choice they face. And so I'm glad to see that Hillary Clinton is atoning for her vote in favor of Lieberman-Kyl by cosponsoring a resolution that states that any funds used to attack Iran must go through an explicit process of congressional approval. The bill, of course, is unlikely to pass, but if Democrats are willing to stand behind it, they can publicize the problem and make action by the Bush administration significantly less likely.
