Published in 2002, this study of the history of terrorism from ancient Rome to the present was among the first to provide a precise definition of terrorism, one that has endured and made the book a landmark book in the field: Once again, reviews were extreme but mixed: some did not share the opinion of the Christian Science Monitor, which foretold correctly that, "After the deadly attacks against the United States, many Americans may now find Carr’s earlier arguments prescient and his approach the only one that has a chance of working;" instead, many critics agreed with Newsweek’s opinion that, ""The Lessons of Terror" is so earnest, so well informed and so outrageous…that almost any reader will find something to love and something that will make you want to throw the book across the room.
