The evil genius of terrorism is that that maximizes unfamiliarity, imaginability, suffering, scale of destruction, unfairness. It's really important to understand why terrorism is so frightening because it is a psychological war and until you understand it and try to reduce the dread, until then you become like a force multiplier for the terrorists inadvertently because you'll tend to overreact to terrorist attacks because the dread factor is so high.

My anxiety about disasters is lower. The more you know, the less scary any of this stuff is. And that's my hope for the book. I want to get people's attention and tell them very valuable and ultimately hopeful information, and you find out nothing is as scary as your imagination.

People will help each other because there is a sense of camaraderie that springs up, which is a survival tactic. You help them because you know you might need their help later. And that is incredibly reassuring.

Citizens are not prepared for attacks because there is a bias against the public by nearly every expert and government official. In emergency preparedness, there is this belief that public will panic, that the public is not to be trusted, that there will be looting.

People with military experience seem to do very well in these situations. They've been taught that they can control their destiny, which is half the battle. They also have some experience in getting out of bad situations even if just through training. They know they have to make a plan and follow it and execute it.

We don't talk about that at all as a country. I think that most people assume that there's nothing they could do if a nuclear bomb went off in their city. And that's just not true. Most people would survive most terrorist nuclear attacks because the bombs would likely be much smaller than those we were dealing with in the Cold War.

The health of your family or your office or your city directly affects the health of it after. The better you are at handling high-stress situations with little information, those skills lead to resilience and the ability to recover afterward.
