Probably they will try. But check out mvpel post #36:
The chemical artillery shell is designed to be stable in normal rough armed-forces handling, and only mix the two components thoroughly when fired from a howitzer and spun at 15,000 RPM by the rifling of the howitzer's barrel.
It takes considerable force to break the barrier between the two components in the shell. This force is provided in normal deployment by the forces accelerating the projectile down the gun tube. The extremely high rate of spin provides the through mixing.
I really can't believe that good-soldier-Achamed is going to take a mallet and screwdriver and accomplish the same feat. Even if he manages to breach the barrier separating the chemicals, he stands the risk of mixing just enough sarin to kill himself and the driver.
The explosive charge carried by the shell is designed to split open the projectile. The shell is intended to be airborne and traveling with considerable velocity to ensure through dispersal of the liquid. It is not likely that a shell exploded, sitting in the back of a truck, would do much more then the "IED" detonated by our EOD personnel at the side of the road (the "dud").
It's seems hard to believe but binary weapons (as well as nuclear explosives) are designed with safety in mind. This is done to insure safe storage and transport as well as to prevent you from killing yourself with your own sword.

If you say so. I feel a little better for our people over there. I don't think the terrorists have too many artillery pieces at their disposal.
But the fact that there was one in Iraq leads me to believe there will be more found.
