Kevin Sullivan responds to my post:

I'm not so certain. After all, most reports indicate that the United States had been monitoring the development of this facility for years. In that case, it seems appropriate to applaud President Bush for sitting on this intelligence nugget for a later date, no?

Obama's discretion is not surprising. However, such discretion form the Bush White House - an administration known for its itchy trigger finger - is in fact far more laudable.

And I remain skeptical, much like Andrew, over whether or not this nuclear revelation truly hurts the Iranian position. Remember, the audience here is in Beijing and Moscow, respectively. If they remain mostly unmoved it leaves the West precisely where it was yesterday. As I said, there's a good chance this could become a meaningless bargaining chip for Iran during next week's negotiations, which may only serve to stall discussion on Iran's active and real threats.
