Are Fear and Urbanism at War?

Dense cities are vulnerable to terrorist attacks. Therefore, some scholars argue, we should deconcentrate American cities further, denying future terrorists targets of opportunity. But flee ing dense and diverse cities would undermine one of our greatest strengths in the so-called war on terrorism. Cities have frequently been dangerous places, but over the centuries people have flocked to them because of the economic opportunities and freedom they offer. Asa way of life, urbanism promotes toleration of differences and delegitimizes efforts to root political power in revealed religion. These modern beliefs are essential in the struggle against terrorism. The main threat to cities comes not from terrorism but from the policy responses to terrorism that could undermine the freedom of thought and movement that are the lifeblood of cities.
