How do you know Bush didn't save more lives by going to Iraq, what is someone did have a WMD over there that has not been found of moved and he thwarted it ? I am not saying that is what happened but what if ?

Just like you blaming him for 911, OK - He should have nuked Saudi Arabia to stop 911, is that what you are advocating ? You don't know what the Iraq war may have stopped or how effective it was. I do not 2nd guess any president on the decision to go to war, and neither should you as you do not know what the alternative outcome would have been.
