Yes has been known for years. Saddam’s #2 general in the Air Force, Georges Sada, said the WMD were sent to Syria by Chemical Ali. There were 56 WMD flights disguised as relief flights from Iraq to Syria in 2002.
Sada was Saddam’s only Christian general, and ironically, the only general he could trust to tell him the truth.
I heard General Sada speak at our church. He revealed as an interesting aside that all of Saddam’s kitchen workers were Christian to protect him from being poisoned.
Sada also wrote a great book, Saddam’s Secrets.
Thanks for that background!
