Ambassador Susan Rice writes the following in Tough Love:

The IAEA reported [n 2009] that Iran had enriched some uranium to 20 percent (close to bomb-grade quality) and continued working on warhead designs far longer than previously suspected.

I didn’t understand this reference, so I consulted the the IAEA DG reports from 2009:

November, August, June, February.

Having done so, I still don’t understand the reference. The IAEA was investigating possible Iranian work on RV’s in 2009, but it had been doing so since at least 2005. Even if her claim were true, it seems irrelevant…Rice doesn’t explain whether and to what extent this information impacted the IC’s 2007 assessment that Iran had stopped its nuclear weapons program.
