Even by the US's own standard troops have used chemical weapons in Iraq. More on the RAI broadcast story about WP being used by the US in Iraq:
The assessment was published in a declassified report on the American Department of Defence website. The file was headed: "Possible use of phosphorous chemical weapons by Iraq in Kurdish areas along the Iraqi-Turkish-Iranian borders."
In late February 1991, an intelligence source reported, during the Iraqi crackdown on the Kurdish uprising that followed the coalition victory against Iraq, "Iraqi forces loyal to President Saddam may have possibly used white phosphorous chemical weapons against Kurdish rebels and the populace in Erbil and Dohuk. The WP chemical was delivered by artillery rounds and helicopter gunships."
"When Saddam used WP it was a chemical weapon," said Mr Ranucci, "but when the Americans use it, it's a conventional weapon. The injuries it inflicts, however, are just as terrible however you describe it."
"Given that the US and UK went into Iraq on the ground that Saddam Hussein had used chemical weapons against his own people, we need to make sure that we are not violating the laws that we have subscribed to," he added.
