Sorry...
There are dozens of militaries all over the world that have no chemical weapons, but have chemical decontamination units and vehicles just like this Iraqi unit.
Keep in mind Iran has chemical weapons, and has used them, in the Iran-Iraq war (in smaller quantities than Iraq, but it still happened.)
I realize people desperately want to believe otherwise but reality has to be faced on this one. No particularly interesting smoking gun here.
Or you are afraid a neighbor (e.g., Iran) would use them on you.
Exactly right.
