This title is essential reading for anyone concerned about the potential threat of terrorism from violence-prone individuals in our midst. A new era in terrorism is emerging and the lone wolf is at the fore-front. From Anders Brevik in Norway, who murdered scores of young people, to Nidal Malik Hasan in the US, who killed many of his fellow soldiers after opening fire at a military base, lone wolves have demonstrated that they can be as dangerous as organized terrorist groups. Who are these terrorists, and what can be done about them? In Lone Wolf, internationally renowned terrorism expert Jeffrey D. Simon presents the first comprehensive treatment of this important issue. Delving into the diversity in motivations and backgrounds of lone wolf terrorists, Simon reveals a number of important and timely conclusions about this growing threat.
