I shall conveniently ignore the rest of your post so that I may easily make this point: Saddam wasn't supported by the U.S. during the Gulf War because he was a different person then. He was supported by the U.S. during the Gulf War because we were trying to pick the lesser of two evils; neither choice was anywhere near what you would call "good," but Saddam was deemed a little more likely to join forces with us.
Now I will run away as quickly as I can in order to avoid the inevitable flames to come. Adios!
