America was lured into the Iraq war by what appeared to be substantive physical evidence of chemical weapons production and stockpiling. It turned out this was not the case. Conversely, substantive evidence of chemical weapons production, stockpiling, and use in Syria did not cause the war cry once heard from pro-Iraq war voices.
