"[W]e have seen reports about the use of chlorine in bombs that had the effect of chemical weapons. Chlorine itself historically has not been listed as a chemical weapon, but when it is used in this fashion, can be considered a prohibited use of that particular chemical. And so we’re working with the international community to investigate that and, in fact, if we have the kinds of confirmation that we need, we will, once again, work with the international community and the organization charged with monitoring compliance by the Syrian government, and we will reach out to patrons of Assad, like Russia, to put a stop to it."
Chlorine "historically has not been listed as a chemical weapon"? Oh really? On April 22, 1915, the Germans released 168 tons of chlorine gas against French troops at Ypres, killing and wounding some 5,000 soldiers and punching a massive hole in the French line. Two days later, the Germans attacked Canadian troops northeast of Ypres with chlorine gas, killing and wounding another 6,000 soldiers.
Chlorine gas becomes hydrochloric acid in the lungs and can certainly be fatal.
Nice try, Mr. President.
