Tell that to the thousands of Kurds who were killed by this stuff in N. Iraq. It is foolhardy to say that the threat of N.B.C. weapons is insignificant. Although the release of Sarin gas in the Japanese subway killed only 1% of the victims, it was a very small release and of low quality chemicals by a fringe group. I guarantee Iraq has world class biological and chemical weapons that could be far more devestating. Also, SFC Thomas fails to point out that a large % of our defenses (masks, suits) are defective and can only scrub these agents for a limited period. Repeated shelling with chemical and biological artillery would cause some problems. I am not saying that we are not as prepared to combat these threats, but I think that this ex-DS is discounting the capabilities of our enemy.
