You mean the chemical weapons program built by Germany and the UK, supplied with precursors by further countries such as the Netherlands, Singapore and India?

As part of Project 922, German firms helped build Iraqi chemical weapons facilities such as laboratories, bunkers, an administrative building, and first production buildings in the early 1980s under the cover of a pesticide plant. Other German firms sent 1,027 tons of precursors of mustard gas, sarin, tabun, and tear gasses in all. This work allowed Iraq to produce 150 tons of mustard agent and 60 tons of Tabun in 1983 and 1984 respectively, continuing throughout the decade. All told, 52% of Iraq's international chemical weapon equipment was of German origin. One of the contributions was a £14m chlorine plant known as "Falluja 2", built by Uhde Ltd, then a UK subsidiary of German chemical company Hoechst AG;[6] the plant was given financial guarantees by the UK's Export Credits Guarantee Department despite official UK recognition of a "strong possibility" the plant would be used to make mustard gas.[7] The guarantees led to UK government payment of £300,000 to Uhde in 1990 after completion of the plant was interrupted by the first Gulf War. Saddam’s son Qusay was said to have been put in charge of concealing chemical weapons from international inspectors.[8][7] In 1994 and 1996 three people were convicted in Germany of export offenses.[9]

The know-how and material for developing chemical weapons were obtained by Saddam's regime from foreign sources.[53] Most precursors for chemical weapons production came from Singapore (4,515 tons), the Netherlands (4,261 tons), Egypt (2,400 tons), India (2,343 tons), and West Germany (1,027 tons). One Indian company, Exomet Plastics, sent 2,292 tons of precursor chemicals to Iraq. Singapore-based firm Kim Al-Khaleej, affiliated to the United Arab Emirates, supplied more than 4,500 tons of VX, sarin and mustard gas precursors and production equipment to Iraq.[54] Dieter Backfisch, managing director of West German company Karl Kolb GmbH, was quoted by saying in 1989 that "for people in Germany poison gas is something quite terrible, but this does not worry customers abroad."[

The chemical weapon attacks that the CIA tried to blame on Iran, despite knowing it came from Saddam?

Joost Hiltermann, who was the principal researcher for Human Rights Watch between 1992 and 1994, conducted a two-year study of the massacre, including a field investigation in northern Iraq. Hiltermann writes: "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, show (1) that Iraq carried out the attack on Halabja, and (2) that the United States, fully aware it was Iraq, accused Iran, Iraq's enemy in a fierce war, of being partly responsible for the attack."[30] This research concluded there were numerous other gas attacks, unquestionably perpetrated against the Kurds by the Iraqi armed forces.[62] In 2001, Jean Pascal Zanders of the Stockholm International Peace Research Institute (SIPRI)'s Chemical and Biological Warfare Project also dismissed the allegations, arguing that "The coloring of the victims is more suggestive of sarin, which was in Iraq's arsenal.

The West created the threat themselves as they were happy for Saddams Iraq to slaughter Iranians with these chemical weapons.
