The restraint isn't that amazing, poison gas is very hard to use effectively on the battlefield. I remember one of my science professors (i cannot cite the following info, it's just what i remember) who was doing chemical type stuff for the army in 'nam, telling us that poison gas can only be used when the conditions are just right, there's simply too much risk of it dispersing or blowing in the wrong direction. Poison gas is scary but, tactically speaking, it's not a very good weapon.
