... he was killing Iranians.
At the same time he was killing Kurds, which we knew about at the time.

that same article in the National Security Archives.

The U.S., which followed developments in the Iran-Iraq war with extraordinary intensity, had intelligence confirming Iran's accusations, and describing Iraq's "almost daily" use of chemical weapons, concurrent with its policy review and decision to support Iraq in the war [Document 24]. The intelligence indicated that Iraq used chemical weapons against Iranian forces, and, according to a November 1983 memo, against "Kurdish insurgents" as well [Document 25].
What was the Reagan administration's response? A State Department account indicates that the administration had decided to limit its "efforts against the Iraqi CW program to close monitoring because of our strict neutrality in the Gulf war, the sensitivity of sources, and the low probability of achieving desired results." But the department noted in late November 1983 that "with the essential assistance of foreign firms, Iraq ha[d] become able to deploy and use CW and probably has built up large reserves of CW for further use. Given its desperation to end the war, Iraq may again use lethal or incapacitating CW, particularly if Iran threatens to break through Iraqi lines in a large-scale attack" [Document 25]. The State Department argued that the U.S. needed to respond in some way to maintain the credibility of its official opposition to chemical warfare, and recommended that the National Security Council discuss the issue.
In 2003 we used the argument that Saddam "killed his own people" as justification to start the war. It's funny how we weren't as concerned about it while it was actually happening.
