ElBaradei's record of omniscience is a bit mixed.
If Tehran nukes Tel Aviv, you think ElBaradei's going to lose his job? Or even take a pay cut? The number of times he's been blindsided exceed the number of times he's been right.
He has absolutely no real incentive to do anything about nuclear problems that actually are uncovered, and even if he did, he has no real power to accomplish anything.
He chewed out Israel for not informing him about any possible nuclear issues with Syria. Why should they? Israel knew two things: that he was completely ignorant of the problem in the first place, and that if he knew about it, he would do exactly what he's doing with Iran, which amounts to year after year of Olympic-level wanking.
