Is the US sincere in its fury about the alleged chemical attack in Syria? If this were more than theatrics, it would repent of its role in the 1980-88 Iran-Iraq war. More than 30 years ago the Iraqi regime was regularly delivering devastating chemical barrages against Iran. The US knew all along that Saddam Hussein, the Iraqi leader at the time, had been using mustard gas and sarin since 1983. Roughly 20,000 Iranian troops were killed by chemical weapons (CW) in that war.
