Terrorism is a means to an end: that of coercive publicity. It will happen. It will happen especially where we polarise confrontations of race and religion round the world. It will happen when weak people cannot resort to armies or bombs or drones, to gain leverage in enforcing their ideas of how society should be run. There is no such thing as a terrorist state. There are just people who use terror as a means to an end.The only power that can be deployed against this curse is the power of perspective. It is to treat terror as a criminal means of making a point. This has not changed since Joseph Conrad described the terrorist as “terrible in the simplicity of calling madness and despair to the regeneration of the world … like a pest in the street full of men”. What cannot be prevented is best accommodated. It is the psychological price we pay to live in an open and liberal society.These dangers pale against those our grandparents and their forebears had to manage. We are incomparably safer than humanity has ever been before. A community that can devote so much attention to suppressing contentious gatherings, offensive remarks and “invalidations of my identity” is not a society under existential threat. As for how best to help the traumatised people of New York, the answer is to do the opposite of what Americans did to European cities hit by such killings, which was to boycott them. The answer is to book a New York holiday, now.
