I want to know what you think was the most effective chemical used in battle. The canadates are: Mustard Gas, Tear Gas, Sarin, VX, Hydrogen cyanide, Chlorine, Hydrocyanic acid, Ricin, and Agent Orange. (REMINDER!: Agent Orange was an herbicide, and has a bit of controversy behind it...so you may have to do a little research on Agent Orange.)
Look into criteria such as: long-term effects, short-term effects, economical and political advantages (if any), death-tolls from each, uses, etc.
