Now, I have no particular view on whether they actually collaborated with Saddam...
That means I have a neutral position on whether or not these terrorists collaborated with Saddam or other Baghdad authorities, because I have insufficient information from which to draw a conclusion. However, I would add this as an aside: If Saddam wanted these particular terrorists to have WMD, then it seems reasonable to conclude that he would simply hand them refined, weaponized anthrax/sarin/whatever, rather than leave them brewing crude ricin in makeshift labs up in the mountains....
I brought that matter up before, and was vigorously flamed for my observation. I did not relish a repeat of that experience...
