Even a monster like Adolf Hitler had compunctions against using chemical weapons.
Some say it was because of his suffering after having been mustard-gassed during the Great War.
Arabs like ISIS and Saddam Hussein (RIPieces you dirtbag) have no such compunctions. Chlorine gas is as bad if not worse than mustard gas.
In this sense, these muslims are worse than Nazis.
Mustard gas leaves a lasting residue that is a hazard to even so much as touching your skin. Germany hurt a whole lot of its own soldiers during WWI because trying to control your own weapon. This is especially true when you are on the defensive. Hitler knew that chem weapons would take out his own defenses, so he woukd not use it. He wanted as many able strong fighting troops as he could muster.
He also knew that if he did use such weapons , the allies would retaliate and not give much of a defensive fighting chance.
Even a monster like Adolf Hitler had compunctions against using chemical weapons.
My great grandparents would beg to differ.
