Gassed Masked?

We may never know the full extent to which chemical warfare factored into Iraqi battle tactics from 1980 through 2003.

Right after Saddam Hussein's execution, the History Channel played biographies of his Evilness, some of them freshly remixed for the occasion.

We'd suspected these programs of getting at least funded, if not placed, by U.S. Department of Defense publicists.

The shows all gave greater certainty to what we'd thought were still allegations of a stockpile full of like poison gas, especially nerve agents.

But these documentaries also skirted the question of how long each of these gases lingered in the environment.
