that's the million dollar question, isn't it? ;)
there are things we know. we know from the UN reports that there are tons of material missing. stuff they know he had, and is now gone. we know there are no documents that tell what happened to this material. this from a regime that was into documenting everything, including criminal acts. we know that intel from Jordan had him with mobile WMD platforms. this was the thing that concerned his neighbors the most. we have some confirmed intel of convoys leaving iraq for Syria while we were messing around with the UN. what was in them? we don't know. we have reports from those within the country of things being moved to the Bekaa valley, but no confirmation.
we simply don't know. he could have dumped the stuff in the sand and killed those who knew he'd had it done....
here's some of what we do know. we know he had the material. we know he had used it. we know that he had tried to get nuclear material in the past. we know from his scientists that they were instructed to keep the knowledge about making of WMD including nucs safe. we know that they were closely monitored and kept from the UN inspectors when interviews were called for. Saddam and his scientists claimed they intended/expected to re-start the WMD program without restrictions as soon as UN sanctions were lifted. France, Germany, and Russia were behind the lifting of sanctions. France, Germany, and Russia were selling prohibited items to Iraq and the bank in France that was to oversee the OFF money was laundering funds for those prohibited items...among other things. we know that Saddam had LOTS of money because of these illegal operations. we know that he was a financial supporter of terrorists in the "Palestinian" territories, and there is evidence that AQ members had been in and out of Iraq and had met with high ranking Iraqi military. he engaged in genocide not only against the Kurds, but other ethnic groups in Iraq.
it would have been better for all if Bush 1 had finished the job. thank you again, UN and Powell. it would have been second best if BC had gone in and done the job under the terms of the cease fire of '91. if you read what BC said about Saddam and what congress published in '98, he had every justification for going back. it would have been better this time to have skipped the UN instead of giving the guy and year to harden defenses and screw around with the inspectors......again
the good thing is that a whole bunch of AQ came to iraq to be killed so that we did not have to chase them out of caves. it's also a great place for us to have a base of operations in the middle east. if there is any country in the middle east that has a chance of joining with the moderate Arab and Persian countries, it is Iraq.
