How many of us here on FR said WMD were in Syria back in the day?
Plenty made that claim but so far there is no way to know if that’s what happened.
Depending on the type of WMD involved we should have found evidence of it remaining in Iraq. Precursors, manufacturing equipment, a lab properly configured, something like that. The only WMDs we know Saddam definitely to have possessed are chemical artillery shells.
The problem with most of the WMD claims leading up to Gulf War II is that they came from Ahmed Chalabi who turned out to be a con man.
