Something For Everybody in IAEA Report

The latest report by the IAEA regarding Iran's nuclear ambitions is a bit confusing. On the one hand, the agency now knows less than it ever did about the Iranian nuclear program. On the other hand, Iran is now increasingly cooperating with the IAEA. Each side of the debate over whether to do anything against Iran, economically or militarily, can use this ambiguous report to bolster its arguments. Just pick one part of the report and ignore the other.

Now here's the big question: if Iran is cooperating more than before, how come Mohamed ElBaradei's crack team of experts knows less than in the past? Either the cooperation is still very partial, even if better than before, or the IAEA is just incompetent. Which one is it?
