As part of the epigraph I used to lead my novella The Time Bridge at Orion, George Orwell wrote, “Poison gas, the machine-gun, the submarine, gunpowder, and even the crossbow were similarly denounced in their day.” This was about the V1 missiles being fired on London at the time.
It is interesting that Orwell put poison gas in the same category as these other weapons. That was war. You do what you need to do. He was very practical about it.
Some people like to think of WMDs as being out of bounds, never to be used — ever. They wish to think the same of torture. But in reality, WMDs are merely being reserved for whatever may be the most dire of emergencies. Treaties on poison gas say “never” but history says something else. People will do what they feel they need to do.
This shouldn’t apply to Assad. He had other options. His recent use was probably just a test to see what the price would be. All of these boundaries will shift when Iran has nukes. The restraints on chem and bio warfare may then be loosened as well.
This may become a much more dangerous world.
