Again, there is no validity to the assumption Syria's precursor chemicals came from Iraq.
There are two precursors to sarin, one of which is a controlled substance under the Chemical Weapons Convention. Methylphosphonyl difluoride.
The other is simple rubbing alcohol, which obviously is not banned.
These two chemicals may be mixed in flight or just prior to use to create sarin.
The shelf life of methylphosphonyl difluoride is five years, according to experts, and I have provided the link.
If Saddam Hussein had methylphosphonyl difluoride, which he likely did, it would be extremely unlikely it is being used by Syria ten years later.
Methylphosphonyl difluoride can be manufactured from substances which are commercially available. Those would not have to be smuggled out of Iraq and into Syria. They can be bought openly any time.
So again, very unlikely Syria got its chemical weapons components from Saddam.
If Syria does not have the technical ability to make methylphosphonyl difluoride, then I would look to Iran or Egypt as the source.
.
The fact that Dow Chemical sold pesticides that are supposed to be used to kill bugs, and Saddam used them to make WMD's proves that Reagan gave WMD's to Saddam.
Did I get that right?
