Note: Chemical Ali is the spitting image of Saddam himself!
I always wondered how many of Saddam (and Uday, et al’s) look alikes were executed/assassinated after the original creeps were caught/killed. They would have known details “on the inside” and many did not choose that life but were drafted for the positions under threat of force.
Who knows what they saw or even knew about everything from weapons programs (when someone talked to them who shouldn’t have) to the way they people/things were hidden from the public (e.g. Saddam’s spider hole).
