Bruce Schneier believes so:
Resilience — building systems able to survive unexpected and devastating attacks — is the best answer we have right now. We need to recognize that large-scale attacks will happen, that society can survive more than we give it credit for, and that we can design systems to survive these sorts of attacks. Calling terrorism an existential threat is ridiculous in a country where more people die each month in car crashes than died in the 9/11 terrorist attacks.
If the U.S. can survive the destruction of an entire city — witness New Orleans after Hurricane Katrina — we need to start acting like it, and planning for it. Still, it’s hard to see how resilience buys us anything but additional time. Technology will continue to advance, and right now we don’t know how to adapt any defenses — including resilience — fast enough.
