It is hard to believe that, during most of the 1980s, America knowingly permitted the Iraq Atomic Energy Commission to import bacterial cultures that might be used to build biological weapons.
But it happened.
Congressional Record: September 20, 2002 (Senate) Page S8987-S8998
...
According to former officials the bacterial cultures
could be used to make biological weapons, including anthrax.
...
A letter written in 1995 by former CDC Director David Satcher to former Senator Donald W.
Riegle, Jr., points out that the U.S. Government provided nearly two
dozen viral and bacterial samples to Iraqi scientists in 1985--samples
that included the plague, botulism, and anthrax, among other deadly
diseases.
...
a letter dated
January 6, 1994, requesting information from the Centers for Disease
Control and a response to the Honorable Donald W. Riegle, Jr., U.S.
Senator, dated June 21, 1995, from David Satcher, M.D., Ph.D.,
Director; a U.S. Senate Hearing Report 103-900, dealing with U.S.
exports of biological materials to Iraq to the Senate Committee on
Banking, Housing, and Urban Affairs which has oversight responsibility
for the Export Administration Act, and keeping in mind that the U.S.
Department of Commerce approves licenses by that Department for
exports; including also the U.S. Senate hearing report in that matter.
Included in the approved sales are such items as Bacillus Anthracis,
anthrax, Clostridium Botulinum, Histoplasma Capsulatum, which causes a
disease superficially resembling tuberculosis that may cause pneumonia;
Brucella Melitensis, a bacteria which can cause chronic fatigue, and so
on; Clostridium Perfringens, which causes gas gangrene. I believe that
completes the list.
