The Chemicals that were sold to Iraq were under European control. The Mustard gas components came from Germany. Almost all of the chemicals were German or Dutch sourced. If you want to blame the USA or Israel at least get your facts straight. Israel was backing Iran. Germans had built the plant where the gas munitions were manufactured. It was done with the full knowledge of Germany and the EU. The Gulf Arabs were backing Iraq and they pressured the USA to help Iraq since Iran was in a state of hostility against the USA. Iraq invaded Kuwait. Iraq started the hostilities that culminated years later with the removal of the despot maniac. None of this excuses or justifies the Iranian involvement in Syria, Lebanon, Yemen, Gaza and Iraq. Yours is the typical biased European mindset that seeks to blame everyone else for a legacy of European failures and greed. It was the EU that facilitated and enabled the Iranian enrichment of Uranium. First it started with Kraftwerk Union (KWU, a Siemens subsidiary) then it progressed through diplomatic enablement tools like agreements that provided cover for Iran's nuclear ambitions. Although Pakistan was a critical reason for the current enriched uranium, with parts were often sourced from the EU and UK because of a failure to intervene or to control the exports. Canada was an easy safe refuge for purchasing, as were EU based companies that helped conceal purchases and launder funds.
