I doubt he unloaded all of it....but am willing to bet he shipped a bunch of it to Syria and maybe Libya and Iran.
Heck, the French might be hiding them...I can almost hear Villepoint or whatever his name is now, saying 'France was so saddened about the thought of so many young Americans and British soldiers losing their lives in a chemical attack, we took Saddam's chemical weapons for safekeeping. To protect lives!'
