"The nerve gas sarin was released in commuter trains on three different Tokyo subway lines by a terrorist cult group. Sarin was concealed in lunch boxes and soft-drink containers and placed on subway train floors. It was released as terrorists punctured the containers with umbrellas before leaving the trains. The incident was timed to coincide with rush hour, when trains were packed with commuters. Over 5,500 were injured in the attack."

5,000 injured, about a dozen killed, that is not the several thousand cited in the article. Aum shinrikyo tried using sarin again by blowing out of a van, and that didn't hurt anyone but themselves. Getting a hold of chem/bio agents is not the most difficult part, it is weaponizing it. These numbers citied are not realistic. Chem/bio weapons are a threat, but this article is hype. The definitive book on the topic is Toxic Terror by Johnathan Tucker. Also take a look at www.cns.miis.edu.
Also, the question of Iraq's WMD was the extent of the programs after 1991. Be honest about this, there is too much spin on both sides.
