Terror, Security, and Money

In seeking to evaluate the efficacy of post‑9/​11 homeland security expenses–which have risen by more than a trillion dollars, not including war costs–the common query has been, “Are we safer?” This, however, is the wrong question. Of course we are “safer”–the posting of a single security guard at one building’s entrance enhances safety. The correct question is, “Are any gains in security worth the funds expended?”

In this engaging, readable book, John Mueller and Mark Stewart apply risk and cost‐​benefit evaluation techniques to answer this very question. This analytical approach has been used throughout the world for decades by regulators, academics, and businesses—but, as a recent National Academy of Science study suggests, it has never been capably applied by the people administering homeland security funds. Cataloging the mistakes that the U.S. has made–and continues to make—in managing homeland security programs, Terror, Security, and Money has the potential to redirect our efforts toward a more productive and far more cost‐​effective course.

John Mueller is a senior fellow at the Cato Institute and Woody Hayes Chair of National Security Studies, and professor of political science at Ohio State University. He is the author of Atomic Obsession published by Oxford University Press.

Mark G. Stewart is a professor of civil engineering and director of the Centre for Infrastructure Performance and Reliability at the University of Newcastle in Australia.

“Our political and media systems often seem paralyzed or even deranged by the prospect of terrorism. Very few people can talk rationally about the threat, the possible defenses, and what we gain and lose through increased security measures. John Mueller and Mark Stewart are notable exceptions. If you wonder whether airport security really makes sense, or how much is “enough” in protecting against attacks, consider the calm and convincing case they lay out in this book.”

“Just when you thought that nothing more could be said about the war on terror, John Mueller and Mark Stewart offer a brilliant new analysis and call to action, filled with insight, intelligence, and sharp writing. It’s one of the rare books for which one can say that every politician and informed citizen should read it.”
