As far as I can tell, the _New Yorker_ hasn’t posted Steve Coll’s piece on the Khan network yet, but they have a Q&A transcript on their website “that’s worth checking out.”:http://www.newyorker.com/online/content/?060807on_onlineonly
This excerpt about the time frame for an Iranian nuclear weapon is interesting:
Q: The question of how fast canâ€™t be answered definitively, but could you give us a sense of the estimates and how reliable you think they are?
A: John Negroponte, the director of National Intelligence, has said, in his most recent public assessment, that the American intelligence community believes that Iran may acquire a nuclear capacity some time in the next decade, meaning from 2010 or 2011 onward. From my reporting, I gather that in private briefings the Bush Administrationâ€™s intelligence analysts focus on a five-to-seven-year window, although they emphasize that thereâ€™s a fair amount of uncertainty about this estimate. I think the one assertion that the intelligence community seems comfortable with is that itâ€™s not this year or next year and probably not the year after that. However, the more that is discovered about Iranâ€™s research, the more some analysts wonder whether Iran might be able to move faster than the official forecast indicates.
