What if Saddam had really had WMD's like Bush said when we invaded Iraq? Would he have used them? What would have been his most likely targets? If he had, how would we have responded?
The reason that the Anglo-American forces invaded Iraq in 2003 was that knew very well that Iraq
did not have any WMD capability. That was one of the reasons that other countries would not join the invasion: they knew the intelligence.
Note the difference in the stance to North Korea, where no military attempt was made to prevent the production of nuclear weapons-or effect regime change. Even before the production of a nuclear device, N. Korea was and is well armed with a substantial CBW arsenal.
Iraq
did have a CBW capability in the 1980s, the technology having been supplied by over a 150 companies from around the world including most Nato members. The US government granted at least 771 export licences including those concerning nerve gas agents, and over 40 biological agents, including anthrax. Many of the exports were for 'dual-use' equipment that would certainly be used in missile, nuclear and CBW warfare and were carried out with the full approval and often financial support of the US Administration, Pentagon and intellgence services: this however, did not stop the US administration arresting many company officials and those of their non-US subsidiaries after 1991.
The upshot of this is that Western intelligence services knew, down to the last can of fly-spray, where every item of CBW or equipment that could be used in CBW in Iraq was and had supplied that information to the UN teams charged with its destruction after 1991 except where it would embarass the government concerned.
From 1991, Iraq was subject to 'no fly' zones, constant aerial surveillance and penetration by hundreds of western intelligence agents. Every aspect of the economy and military was monitored.
In 2004 Saddam Hussein had admitted to Prince Hassan of Jordan that he had no WMD left, but feared the Iranians would find that out.
No WMD--no story.
