Dr. Kamolnick's book is a meticulously documented investigation and comparison of the al-Qaeda Organization (AQO) and the Islamic State Organization (ISO) across three key strategically relevant dimensions: essential doctrine, beliefs, and worldview; strategic concept, including terrorist modus operandi; and in the final chapter, specific implications, and recommendations for current U.S. Government policy and strategy. Through this comparison, he supplies far greater clarity on, incisive analysis of, and potential answers for such key questions as: How is each terrorist entity related historically and doctrinally to the broader phenomenon of transnational Sunni "jihadism"? What is the exact nature of the ISO? How, if at all, does ISO differ in strategically relevant ways from AQO? What doctrinal differences essentially define these entities? How does each understand and operationalize strategy? What critical requirements and vulnerabilities characterize each entity?
