Imagine you're afraid of spiders. If you seek psychiatric treatment, your therapist will try to convince you that your fear is irrational. She'll tell you over and over again that daddy long legs are harmless and black widows are rare. Ignore the creatures crawling around your attic, she'll say; just live your life.
At least, that's what your therapist will do if she's good at her job. If she's bad at it, she'll tell you that spiders represent a significant threat to your safety. Your anxiety will spiral out of control and may seriously damage your health.
In response to aggression from the Islamic State in Iraq and the Levant, Western leaders are acting like the bad therapist — building up the threat instead of putting it in perspective, even using it as an excuse to stoke xenophobia. If they keep at it, our communal anxiety will spiral out of control and may seriously damage our collective health.
Fear of terror can disrupt and worsen our lives in the absence of an actual attack. For instance, recently a single e-mail from an unknown source led to school closures across Los Angeles at a cost of more than $20 million.
To Israelis, this is an old story. During the darkest months of the second Palestinian intifada in my country, when suicide bombers occasionally blew themselves up in public places, terror — not terrorism, but terror — almost obliterated the public sphere. I recall that going out for dinner or to the theater was considered suicidal. However, the objective risk of being involved in a terror attack at a restaurant or theater wasn't much greater than the risk of being involved in a car accident during a normal drive home from work. Tourism was almost nonexistent despite the fact that the homicide rate in Washington, D.C., was far higher during that period than the combined death rate from homicide and terror in Israel.
In 2004, the last full year of the intifada, more people were killed in the New Orleans metropolitan area than in the entire nation of Israel, counting civilian intefadeh victims.
When a good therapist treats an anxious patient, she tells him to divert his attention away from the cause of the anxiety as much as possible. Scared of spiders? Don't think about spiders.
Politicians do the opposite. They never mention that Westerners are statistically more likely to drown in a bathtub than die in a terrorist attack. They'd rather drone on about eradicating terrorism and reaching its perpetrators wherever they are; they'd rather rehearse the biography of every terrorist and every victim. That's analogous to entertaining a crowd of hypochondriacs with gruesome descriptions of hospital emergency rooms.
