We also provided him with heavy trucks that were later used in the invasion of Kuwait, and helicopters that were modified for military use.
We provided numerous dual-use items.
He could not have built his arsenal as it was without US help. Of course, this arsenal is no longer in existence, but that's not what you asked :).
"During the Iran-Iraq war, Iraq received the lion's share of American support because at the time Iran was regarded as the greater threat to U.S. interests. According to a 1994 Senate report, private American suppliers, licensed by the U.S. Department of Commerce, exported a witch's brew of biological and chemical materials to Iraq from 1985 through 1989. Among the biological materials, which often produce slow, agonizing death, were:
* Bacillus Anthracis, cause of anthrax.
* Clostridium Botulinum, a source of botulinum toxin.
* Histoplasma Capsulatam, cause of a disease attacking lungs, brain, spinal cord, and heart.
* Brucella Melitensis, a bacteria that can damage major organs.
* Clostridium Perfringens, a highly toxic bacteria causing systemic illness.
* Clostridium tetani, a highly toxigenic substance.
Also on the list: Escherichia coli (E. coli), genetic materials, human and bacterial DNA, and dozens of other pathogenic biological agents. "These biological materials were not attenuated or weakened and were capable of reproduction," the Senate report stated. "It was later learned that these microorganisms exported by the United States were identical to those the United Nations inspectors found and removed from the Iraqi biological warfare program."
The report noted further that U.S. exports to Iraq included the precursors to chemical-warfare agents, plans for chemical and biological warfare production facilities, and chemical-warhead filling equipment.
The exports continued to at least November 28, 1989, despite evidence that Iraq was engaging in chemical and biological warfare against Iranians and Kurds since as early as 1984.
The American company that provided the most biological materials to Iraq in the 1980s was American Type Culture Collection of Maryland and Virginia, which made seventy shipments of the anthrax-causing germ and other pathogenic agents, according to a 1996 Newsday story."
