GOOD THING THERE ARE NO CHEMICAL WEAPONS IN IRAQ: ISIS suspected of mustard attack against US and Iraqi troops.

The shell was categorized by officials as either a rocket or artillery shell. After it landed on the base, just south of Mosul, U.S. troops tested it and received an initial reading for a chemical agent they believe is mustard.

No U.S. troops were hurt or have displayed symptoms of exposure to mustard agent.

One official said the agent had “low purity” and was “poorly weaponized.” A second official called it “ineffective.”

Ineffective or not, ISIS doesn’t fear us enough to refrain from attempting to use a weapon of mass destruction.
