Americans have been shocked in the past few years to discover how vulnerable our nation is to disaster, be it terrorist attack or act of God. But what's truly shocking, argues leading security expert Stephen Flynn, is how little we have learned from the cataclysms of September 11 and Hurricane Katrina. When it comes to catastrophe, America is living on borrowed time-and squandering it. In this eye-opening, vitally important new book, Flynn issues an overdue wake-up call demanding that we shake off our denial and sense of helplessness and start preparing immediately for a safer future.
