I think that, if you intend to use chemical, biological, or nuclear weapons against an invading army, it makes sense first to evacuate civilians from the places where you intend to use those weapons.

True, and in doing so, like the Germans in WWI, we know where not to be.

Actually pretty considerate to put up a "danger" sign, at least for a bloodthirsty nutbar like Saddam.

I can't imagine that Saddam cares. These are Kurds, and he's gassed Kurds before.
I'd more likely believe that this is the area where he intends to station his troops.
