From 2005 with relevancy for today:
Nuclear and emergency preparedness experts, as well as federal reports, show that America has failed to brace itself adequately for a nuclear attack. This failing reveals something important about our human nature.
Human nature tends to forget about unpleasant realities. “Men stumble over the truth from time to time,” Winston Churchill said, “but most pick themselves up and hurry off as if nothing happened.”
Nuclear warfare is one of those unpleasant realities. With the dark cloud of Cold War long passed, we want to believe the nuclear threat has evaporated with it. In truth, however, nuclear capability is now more decentralized and diffuse; nuclear material has proliferated; and we live in an age of terrorism. In short, the threat has never been greater.
