Much of this is not new. Read about these WMD finds and some related illnesses years ago.
What you did not read about were the green C/B weapons- suits my son and his squad seized on the eastern Euphrates bank area in the Hindaya city area after Operation Peach was finished on April 3, 2003 (54th Engineers Battalion with the 299th MRB Company out of Ft. Belvoir, Va).
Unfortunately my son did not have a camera with him and was too busy taking care of surrendering Iraqi Army regulars who quit after seeing the famed Republican Guard tank divisions blown to hell.
Some other chemicals were seized around Iraq, including about 50 pounds of cyanide powder (there were photos and articles on this seizure).
Saddam had chemical weapons from the Iraq-Iran war, the attacks on the Kurds, and from traditional military caches (1980s and 90s). The fact that he did not use them on our forces during OIF was due to the fact that we would have nuked him.
My father was a CWS officer during WW2 and his unit sent Poison Gas shells to Australian depots incase the Japanese used gas during the upcoming planned invasion of their country.
Just because something is not used doesn’t mean it doesn’t exist. We still do not know what was in the reportedly Russian escorted convoys from Iraqi weapons depots to Syria immediately before OIF began.
Same thing I'm wondering about. I was hearing about this from multiple informed sources at that time. Haven't seen any good follow-up on it since.
