That really is a pathetic cuscus belli for invading Iraq, considering that the Regan administration fostered close relations with the Iraqi’s at the time of those atrocities, who saw them as a counterbalance to Iranian influence in the Middle East.
Most of the gassing (Simply saying ‘gassing’ certainly doesn’t even begin to provide an accurate picture of the horrendous injustices committed by Saddam’s regime against the Kurds during this period, I might add.) attacks occurred during the late 1980’s, which generally encompass the Al-Anfal campaign, and the Halabja massacre. However, the United States, overlooked these events, and throughout the conflict, provided Iraq with economic, military and diplomatic support.
The Riegle report, found that, during the period of 1985-1989, the United States had provided biological agents to Iraq, that: “Could have been cultured or grown in large volume in an Iraqi biological warfare program”. It’s quite ironic for someone like George Bush to say that Saddam is a danger because he “Gassed his own people”, when in fact, the United States was assisting Saddam expand his chemical weapons capabilities.
During the Halabja massacre where the Iraqi government killed 3,000 Kurds in a single gas attack, the US State department, to obscure responsibility, asserted that Iran was also culpable in the attack, despite knowing that Iranian invovlement was a fallacy.
Finally, in 1988, the US congress introduced the Prevention of Genocide of 1988, which sought to punish Iraq for its attacks on the Kurds, speaking of the bill, Jesse Helms said: “This legislation will help demonstrate to the Iraqi regime just how seriously our country views its campaign against the Kurds. In addition, it will help assure that US tax dollars do not subsidize the Iraqis.”
Reagan threatened to veto the bill, and the administration heavily lobbied for its defeat. Needless to say, the bill did not pass.
So, being one of the fallback justifications for invading Iraq, the argument is pretty weak, unless it symbolizes US foreign policy as being “You can genocide your people and we’ll completely ignore it, however, 20 years down the track, we might use it as a reason to attack you”. So, we might expect to be invading Sudan in 2024.
