That’s one heckuva NIE on Iran

We judge with high confidence that in fall 2003, Tehran halted its nuclear weapons program; we also assess with moderate-to-high confidence that Tehran at a minimum is keeping open the option to develop nuclear weapons. We judge with high confidence that the halt, and Tehran?s announcement of its decision to suspend its declared uranium enrichment program and sign an Additional Protocol to its Nuclear Non-Proliferation Treaty Safeguards Agreement, was directed primarily in response to increasing international scrutiny and pressure resulting from exposure of Iran?s previously undeclared nuclear work.... Tehran?s decision to halt its nuclear weapons program suggests it is less determined to develop nuclear weapons than we have been judging since 2005. Our assessment that the program probably was halted primarily in response to international pressure suggests Iran may be more vulnerable to influence on the issue than we judged previously.... Our assessment that Iran halted the program in 2003 primarily in response to international pressure indicates Tehran?s decisions are guided by a cost-benefit approach rather than a rush to a weapon irrespective of the political, economic, and military costs. This, in turn, suggests that some combination of threats of intensified international scrutiny and pressures, along with opportunities for Iran to achieve its security, prestige, and goals for regional influence in other ways, might?if perceived by Iran?s leaders as credible?prompt Tehran to extend the current halt to its nuclear weapons program. It is difficult to specify what such a combination might be. (emphases added) These are the key paragraph of the latest National Intelligence Assessment on Iran. In a separate New York Times story, Mark Mazzetti tries gets at some of the implications. Much as I would like to conclude that multilateral economic pressure had an effect, I'm not sure how the NIE concludes that "international pressure" had an effect. If that was truly the case, why did the suspension take place in 2003 rather than later? I mean, gee, what was happening then? One obvious implication: whatever slim chance there existed of a U.S. military intervention in Iran over the next 13 months just got way, way slimmer. Developing.... UPDATE: Kevin Drum provides some useful backstory.
