Insurgents launched three more chlorine truck attacks in Al Anbar province on March 17, killing two and sickening an additional 350. Is this a disturbing new trend? No. Had those trucks been filled with high explosives, each could have killed around 100 people. Instead, combined, they killed two. Probably all those sickened will recover with little or no lasting damage, as opposed to losing limbs and eyes. Chemicals have never lived up to their reputation as weapons.

That's why even though the Germans invented Sarin gas, which is vastly more deadly than chlorine, they decided not to use it. Hitler didn't forego its use because he was a nice guy. Rather, his generals convinced him that high explosives are far more effective in causing deaths, not to mention that all the poison gas in the world can't destroy material objects. That said, gas is a good terror weapon because most people have a more innate terror of being gassed than of being blown up or shot. But that's primarily or exclusively because gas is such a rare threat. The more the terrorists use chlorine, the less the terror effect will be.
