So has every President of the United States. Remember Sadaam Hussein, the Shah of Iran and Manuel Noriega? They were our guys. Donald Rumsfield in a famous photo op was in Iraq shaking hands after selling Hussein arms. In 1988 Hussein later used to chemical weapons to kill his people in Halabja. Bill Clinton suspended the no fly zone over Iraq so Hussein could respond to a Shia uprising (Shia’s were the majority population in Iraq). Hussein used the suspension to further wipe out Shia resistance.
Sources Wikipedia The U.S. State Department, in the immediate aftermath of the incident, took the official position that Iran was partly to blame. A preliminary Defense Intelligence Agency (DIA) study at the time reported that Iran was responsible for the attack, an assessment which was used subsequently by the Central Intelligence Agency(CIA) for much of the early 1990s. The CIA’s senior political analyst for the Iran-Iraq war, Stephen C. Pelletiere, co-authored an unclassified analysis of the warwhich contained a brief summary of the DIA study’s key points. The CIA altered its position radically in the late 1990s and cited Halabja frequently in its evidence of weapons of mass destruction before the 2003 invasion of Iraq. Pelletiere claimed that a fact that has not been successfully challenged is that Iraq was not known to have possessed the cyanide-based blood agents determined to have been responsible for the condition of the bodies that were examined, and that blue discolorations around the mouths of the victims and in their extremities, pointed to Iranian-used gas as the culprit. Leo Casey writing in Dissent Magazineargued that “none of the authors of these documents […] had any expertise in medical and forensic sciences, and their speculation doesn’t stand up to minimal scrutiny.”
Joost Hiltermann, who was the principal researcher for Human Rights Watch between 1992–1994, conducted a two-year study of the massacre, including a field investigation in northern Iraq. According to his analysis of thousands of captured Iraqi secret police documents and declassified U.S. government documents, as well as interviews with scores of Kurdish survivors, senior Iraqi defectors and retired U.S. intelligence officers, it is clear that Iraq carried out the attack on Halabja, and that the United States, fully aware of this, nevertheless accused Iran, Iraq’s enemy in a fierce war, of being partly responsible for the attack. This research concluded there were numerous other gas attacks, unquestionably perpetrated against the Kurds by the Iraqi armed forces. According to Hiltermann, the literature on the Iran-Iraq war reflects a number of allegations of chemical weapons use by Iran, but these are “marred by a lack of specificity as to time and place, and the failure to provide any sort of evidence.” Hiltermann called these allegations “mere assertions” and added that “no persuasive evidence of the claim that Iran was the primary culprit was ever presented.” An investigation conducted by Dr Jean Pascal Zanders, Project Leader of the Chemical and Biological Warfare Project at the Stockholm International Peace Research Institute, into responsibility for the Halabja massacre also concluded in 2007 that Iraq was the culprit, and not Iran.
In August 2013, Foreign Policy charged, based on recently declassified CIA documents and interviews with former intelligence officials, the U.S. had firm evidence of Iraqi chemical attacks beginning in 1983. Saddam’s regime also received intelligence assistance from the CIA in 1987 prior to the Iraqis’ early 1988 launch of sarin attacks to stop the potentially decisive Iranian offensive to capture the southern city of Basra, which, if successful, might have resulted in a collapse of Iraqi military and government.
