Conveniently, articles like this always leave out how some European nations directly and knowingly helped Saddam with his chemical weapons programs, such as Germany and the UK. It was a united effort by the West, just as the vast destruction of Syria has been.

"As part of Project 922, German firms helped build Iraqi chemical weapons facilities such as laboratories, bunkers, an administrative building, and first production buildings in the early 1980s under the cover of a pesticide plant. Other German firms sent 1,027 tons of precursors of mustard gas, sarin, tabun, and tear gasses in all. This work allowed Iraq to produce 150 tons of mustard agent and 60 tons of Tabun in 1983 and 1984 respectively, continuing throughout the decade. All told, 52% of Iraq's international chemical weapon equipment was of German origin. One of the contributions was a £14m chlorine plant known as "Falluja 2", built by Uhde Ltd, a UK subsidiary of a German company; the plant was given financial guarantees by the UK's Export Credits Guarantee Department despite official UK recognition of a "strong possibility" the plant would be used to make mustard gas."
