Not sure if Syria had the tech and capability to manufacture chemical weapons, but we all know Saddam did and even used them on the Kurds. I strongly believe that Syria’s chem/weaps came from Iraq. Need I remind anyone of the long truck convoys leaving Iraq towards Syria just prior to the Iraq invasion?
Do you recall the 100s of trucks passing thru Iraq to Syria? Russions and Germans. We let them go on because they claimed diplomatic immunity.
