I welcomed with great anticipation my copy of Matthew Levitt’s Hezbollah: The Global Footprint of Lebanon’s Party of God. Levitt is also the author of a 2006 book, Hamas: Politics, Charity, and Terrorism in the Service of Jihad. My anticipation for Hezbollah was driven in part by Levitt’s noteworthy background in the subject of terrorist groups, with his work as a researcher and scholar at The Washington Institute for Near East Policy, and as a practitioner at the U.S. Department of State, Department of the Treasury and the FBI. Its timing was stimulating, for the book arrived in the midst of controversy and concern regarding Hezbollah’s deepening role in the Syrian civil war. My anticipation also was fueled by the chance to read Levitt’s work as a detailed refresher to my own late 2008 monograph published by the Combating Terrorism Center at the United States Military Academy titled, Sunni and Shi’a Terrorism: Differences that Matter. As its title implied, that monograph took a comparative, 25 year look at the terrorist activities of groups inspired by radical Sunni Islam and those inspired by radical Shi’a Islam in non-combat zones around the world. Lebanese Hezbollah was a feature Shi’a player in this comparative analysis. Levitt’s work promised a much deeper dive into the world of radical Shi’a terrorist groups.
