1. Chemical weapons are worse than other weapons.
This is not the case. Death and dismemberment are horrific regardless of the weapon. No weapon is being used legally, morally, humanely, or practically in Syria or Iraq. U.S. bombs are no less indiscriminate, no less immoral, and no less illegal than chemical weapons — or for that matter than the depleted uranium weapons with which the United States has been poisoning the area. The fact that a weapon has not been banned does not create a legal right to go into a country and kill people with it.
