Saddam, himself, personally, cannot launch a WMD missile if he is cornered. He would have to order someone else to do it.
If the person so ordered is more rational than Saddam and has a good idea that this order is in desperation (Saddam is near death), "some failure" will probably happen to prevent the launch.
At any rate, even if we assumed that he had a few pounds of biological/nuclear agents in some lab, and we bombed this lab, what do you think the results will be. I imagine the harmful material that was not released in the environment by Saddam, would be released by the US bombing. This material can pollute the air, and harm not only innocent Iraqi civilians, but also all neighboring countries including Israel.
I guess at this point, we should take advantage of the pressure that our President put on Saddam, and the opportunity to get the inspectors back in to continue the process of disarmament. Only through peaceful disarmament that we can safely destroy harmful materials. Bombing harmful materials transfer them from POTENTIALLY HARMFULL MATERIALS TO ACTUALLY DEADLY MATERIALS!!! Yes, our media is whipping us into frenzy to fight this evil guy, and yes we are not going to get exposed to these harmful materials because we are far away from theater of war. However, we should consider the harms and the permanent damage that may result from our attack. I am not a peacenick pinco commie, I am a thinking right wing republican that is more aware of the greater danger of Islamic fanatics around the world. We can deal with dictators after we are finished with the global Islamic terrorism challenge.
