You are incorrect in your assumption that your reason was the reasoning for gas and chemical agents being outlawed. Read up on it, or go to Belgium on 11th month being November 11th, at the 11th hour, and on the moment of the 11th minute as the crowd utters just under their breath the words, “We will remember” which will rise up and move you like nothing you have experienced and then understand why these weapons were outlawed.
I think not. The emotion generated by a seemingly diabolical weapon no doubt prompted it’s outlawing but the use of gas on the battlefields of the First World War ultimately proved impractical. If they were so worked up over it’s use perhaps they should have taken the step to outlaw war altogether but such a thing is wishful thinking at best. Had they had more of a devastating use they most certainly would have been used in WW2. The use of gas in a sealed chamber proved to be the more effective , as the Germans demonstrated in the concentration camps. Ironically outside of Auschwitz, where Zyclon-B, a prussic acid compound was used , the gas of choice in all the others was carbon monoxide, generated by using the diesel motors of captured Russian submarines. As to the European experience, I don’t know of gas being used against civilians in WW1 as it was in WW2. Two generations of men in my family fought for Europe’s freedom and both barely survived doing so. Thank you but I don’t need to be reminded of wars cost.
