"9/11 could join the Trojan Horse and Pearl Harbor among stratagems so uniquely surprising that their very success precludes their repetition"
~ (via Seitz via Schneier) Interesting sentiment. Lots to think of there when it comes to assessing one’s disposition to risk, our current security posture, and the importance of being first in order to succeed. (I shouldn’t have to say it but just in case, I’m measuring “success” as outcome / intended outcome, >=1 being exceptional, and I’m not saying that these attacks were good for the world.)
