> aren't we sending the message that all it will take to completely cripple the US is to kill 25,000 of its citizens? We peace-minded Westerners are an incredibly naive bunch. The world is a brutal "eye-for-an-eye" place -- has been and will always be. Terrorism has impact not only in the number of people killed, but also (1) probably much larger economic impact (people minimizing travel or any other activities that involve risk, even if they are not conscious they are doing so because of terrorism), (2) acts of terror that go unpunished will usually raise the position/status of the terrorist who committed or organized those acts in the internal power hierarchy he's embedded in (that's how fame, or rather "infamy" works), which in turn could lead to an extremely precarious and expensive situation of having to deal not just with a lone terrorist group but with an entire terrorist government, (3) if there is one thing most people want from their governments, it is protection against external threats, and failure to act can be perceived as failure to protect, which in turn will increase risk-avoidance and thereby have an economic impact (see first point). Saying that nothing should be done when terrorists strike is like telling a kid who is being bullied to simply ignore bullies and expect bullying to stop -- it's something that's never said by someone in the position of being bullied, but always by someone who is not impacted by it. In addition, such a statement rests on the false premises that (1) bullying is mostly harmless (it isn't), and (2) that bullies are primarily interested in seeing a response from the bullied kid -- and that they are not bullying him/her for some other purpose (such as scapegoating, or deriving pleasure from the act of bullying itself).
