Nice essay on the futility of trying to prevent another 9/11:
“Never again.” It is as simplistic as it is absurd. It is as vague as it is damaging. No two words have provided so little meaning or context; no catchphrase has so warped policy discussions that it has permanently confused the public’s understanding of homeland security. It convinced us that invulnerability was a possibility.
The notion that policies should focus almost exclusively on preventing the next attack has also masked an ideological battle within homeland-security policy circles between “never again” and its antithesis, commonly referred to as “shit happens” but in polite company known as “resiliency.” The debate isn’t often discussed this way, and not simply because of the bad language. Time has not only eased the pain of that day, but there have also been no significant attacks. “Never again” has so infiltrated public discourse that to even acknowledge a trend away from prevention is considered risky, un-American. Americans don’t do “Keep Calm and Carry On.” But if they really want security, the kind of security that is sustainable and realistic, then they are going to have to.
There’s a lot of good material in this essay.
