Actually, that's no where close to what I'm saying since the attack still happens. It's like the difference between a trauma team working up a patient with prior warning (thus being able to assemble and prepare) and no prior warning. Are you seriously going to argue that the fact that command posts, significant resources on scene, and an operating incident command system both made managing it significantly easier... and is unlikely to be present in pretty much any other incident?
It's like saying Drug X is a wonder drug (given conditions A, B, and C) where conditions A, B, and C pretty much are never present.
