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. Given the limited risk terrorism presents, expenses meant to lower it have for the most part simply not been worth it. For example, to be considered cost-effective, increased American homeland security expenditures would have had each year to have foiled up to 1,667 attacks roughly like the one intended on Times Square in 2010-more than four a day. 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 Woody Hayes Chair of National Security Studies, and Professor of Political Science at Ohio State University. He is the author of Atomic Obsession (OUP 2009).
