Maybe Ijaz was a nuclear scientist when in the middle east...and kept it secret...and pretended to be a broker???
BTW...I think that Zawahiri releasing that video today...talking about the strike in Pakistan ... makes me think more than before that Bin Ladin must be dead...
otherwise, why wouldn't HE have been on tape...after all..HE is the one we wanted mostly.
