Via Brendan Nyhan, Jonathan Landay reports for McClatchey:

Despite President Bush's claims that Iran is pursuing nuclear weapons that could trigger "World War III," experts in and out of government say there's no conclusive evidence that Tehran has an active nuclear-weapons program.

Seems like an important point! Nevertheless, Like Muhammed ElBarradei and the IAEA this McClatchey outfit would have a lot more credibility if it hadn't gotten Iraq so wrong. I'll put my faith in George W. Bush and The Weekly Standard instead.
