Imagine that Saddam had not been executed. Imagine that he had been sentenced to life in prison.
Now imagine that a group of pro-Saddam terrorists seizes an elementary school. They say they will kill all the students and teachers if Saddam is not released within 24 hours.
Should Saddam then be released? Or should several dozen innocent children and their teachers be killed?
Is it not better that we have guaranteed that it will never be necessary to make such a choice?
