Other than hanging Saddam (an non-religious leader), in what manner did we take care of butchers in Iraq? We took a nation with some internal stresses that was being held together by a tyrant. We destabilized it and get loose the Shia against the Sunni against the Kurd. We led to car bombs, people bombs, ISIS beginning, and radicalized hundreds of thousands of people who while discontent with their situation were now willing to kill and be killed instead. We created butchers in fall greater numbers than there were before we got there. And I missed the memo you apparently got that our invasion of Iraq was related to getting Islamic people. Pretty sure even Cheney never voiced that opinion.
