"Chilling... [A] harrowing - and persuasive - picture of the cyberthreat the United States faces today." -- Michiko Kakutani, New York Times "Clarke and Knake are right to sound the alarm." -- Wall Street Journal "[CYBER WAR] may be the most important book about national-security policy in the last several years." -- Slate "In this chilling and eye-opening book, Clarke and Knake provide a highly detailed yet accessible look at how cyber warfare is being waged and the need to rethink our national security to face this new threat." -- Booklist "Will strengthen Clarke's claims as one of the founding fathers of cybersecurocracy...It is worth buying this book if only for his pithy five-page vision of this coming apocalypse and a return to stone-age conditions within a week, all because of a few pesky hackers and viruses." -- Financial Times
