Larry Kelley’s life was utterly changed by 9/11. On the day after the attacks, on his way to work, he was struck by the sudden realization that World War III had commenced. Like most Americans he desperately wanted to find out who were these people who attacked us, what could ordinary citizens do to join the battle and how can those plotting to kill us in future attacks be defeated. Mr. Kelley has written scores of columns on the dangers of western complacency.
