Not to be crass Cookie, but many more Americans die from avoidable causes (e.g. gun crime) every year and that's before we get to the much larger numbers of those dying from preventable diseases and famine in other countries. It was the nature and the scale of the 9/11 attack that was so sickening. And you need to be here to fully understand that. To talk to the ordinary people that faced the horror of that day. Pearl Harbor was a military attack on military personnel (they know the risks when they sign up - at least in England they do). During 9/11 bankers and cooks took the wrath of extremists. That can't be right.
