Stephen M. Walt in Foreign Policy:
When a shocking event like the Paris attacks occurs, we know how the world will respond. There will be dismay, an outpouring of solidarity and sympathy, defiant speeches by politicians, and a media frenzy. Unfortunately, these familiar reactions give the perpetrators some of what they want: attention for their cause and the possibility their targets will do something that unwittingly helps advance the perpetrators’ radical aims.
What is most needed in such moments is not anger, outrage, or finger-pointing, but calm resolution, cool heads, and careful thought. What happened in Paris is an untold tragedy for the victims and deeply offensive to all we hold dear, but we must respond with our heads and not just our hearts. Here are five lessons to bear in mind as we reassess the dangers and search for an effective response.
