As much as I respect Juan's knowledge and judgment, he's seriously off the mark on that point. It is widely accepted among bioweapons experts that Iran has one of the largest stockpiles of chemical weapons in the developing world, and has long been building a germ warfare capability.
In fact, the formidable size of Iran's CBW program and its possession of missiles that can reach targets throughout the region likely saved Iran last year from an Israeli preemptive attack on its nuclear research facilities.
What distinguishes Iran from Iraq is that the former really does have WMDs (non-nuclear), and an attack by the US and/or Israel would result in an effective response with massive casualties. It was the persistant neocon offensive -- spearheaded by Bolton, Miller, Frankin, AIPAC and Israeli intel - to push the US into a war with Iran, despite the huge costs, that resulted in the decision to prosecute the OSP-AIPAC spy ring and Plamegate.
