This obsession with finding weapons of mass destruction ignores the most important part of nuclear weapons development: the workforce necessary to design and assemble them.
The scientists, engineers, technicians, and assembly line workers are far more important than the physical materials. As long as Saddam kept his workforce intact, he would have been able to restart nuclear weapons development at any time.
Saddam regime did not produce the final Chemical Weapons products but was producing and researching the ingredients called Chemical Precursors required to make the final Chemical Weapons. The production of these Chemical Precursors took place from 1999-2002. They did so because if caught they can always claim that these dual materials are for civilian industries and also to deceive the people on these materials that they are doing so for civilian industries, also because the ingredients ( Chemical Precursors) have longer shelf life in storage than the final Chemical weapons. They produced these Precursors under a program called “Pharmaceutical and Pesticides Project” to give it a civilian industry name and for deception purposes as they called their previous nuclear program the “Petrochemical 3 Project”.
Saddam regime hid these Chemical Precursors in the Anbar province also called the Western desert.
The above conclusions and analysis are based on the many Iraqi documents that I read. I will not publicly post the possible locations of the Chemical Precursors as based on three documents I read, and that is because of security concerns. The terrorists who are very active in the Anbar province can get hold to these very dangerous chemical Precursors if they know its locations.
Don't forget about the nuclear weapons program and material that Libya gave up so quickly once Saddam could not strong arm them anymore.
