John Brennan: It’s Almost Impossible to Find Out How Much Uranium Iran Still Has

EXCERPT:

BRENNAN: "That's going to be tough to decide. I know that there was some movement in terms of vehicles at some of these facilities prior to the strikes. So they could have moved some of that highly enriched uranium outside of it. But I think it is going to be up to a variety of intelligence collection systems, whether it be human sources, technical collection, imagery and so on. But the IAEA also will be doing some evaluations. So that bomb damage assessment is going to take some time, but I think unless we have people actually inside of these facilities, we're really not going to have a conclusive view of exactly how extensive and how thorough the damage was."
