zlatan, how many people got killed and maimed by the Syrian civil war? and how many got killed and maimed by chemical weapons? and what chemical weapons are they?
Most incidents involving chemical weapons are by chlorine. Under the convention that the Syrian government signed up to, they did not have to destroy chlorine stocks because chlorine is not a banned chemical weapon. When Sarin was used, not enough quantity was used or left trace for UN people to pin that to Mr Assad, so it could be from any of the factions fighting over there. Assad has no special reason to use anything more than choking agents to force his enemies out into fresh air where they can be shot at by his helicopters, chlorine does just that.
