In the weeks prior to the war to liberate Afghanistan, a good friend of mine would ask me almost every day, “Why aren't we killing people yet?” And I never had a good answer for him. Because one of the most important and vital things the United States could do after 9/11 was to kill people. Call it a “forceful response,” “decisive action” ' whatever. Those are all nice euphemisms for killing people. And the world is a better place because America saw the necessity of putting steel beneath the velvet of those euphemisms.
