This book explores how ordinary Arab-speaking social media users have reacted to propaganda from the Islamic State, rather than how IS propaganda has targeted ordinary users, thus providing a change in perspective in the literature. The authors provide a comprehensive account of the evolution of the Arabic discourse on IS, encompassing all phases of the Caliphate’s political evolution, from the apogee of the Islamic State in October 2014 to the loss of its unofficial capital of Raqqa in September 2017. Taking into account key events, the book also considers the most recurrent topics for IS and its opponents who engage in the Twitter conversation. The analysis is based on around 29 million tweets written in the Arabic language, representing a random sample of around one-third of all Arabic tweets referring to IS over the 2014-2017 timeframe.

Some of the world's most lethal terrorist organizations have become media-centric enterprises, while also hijacking a major world religion, holding large swathes of physical territory, and governing their own virtual states. In this concise and penetrating book, Seib traces how terrorism has proliferated and increased significantly in menace in the relatively brief period between the rise of al-Qaeda and the creation of Islamic State. With close attention to the linkages between media, religion, and violence, the book offers incisive analysis of how organizations such as Islamic State, al-Qaeda, and Boko Haram operate and reflects on how terrorism may continue to evolve. Seib argues that twenty-first-century terrorism is enabled by new media and depends on social networks as connective tissue, while interacting simultaneously with religion and socio-economic and political grievances. As Terrorism Evolves prescribes new measures for counterterrorism efforts, underscores the importance of soft power, and makes a strong case for recognizing that we have entered an era of terrorism of undetermined duration.

Intelligence continues to undergo significant changes at a remarkable pace, notably developments related to “Big Data,” surveillance, and cyber. Intelligence today involves multiagency, multinational, multidisciplinary, multidomain information sharing and sense-making, conducted by commerce, academic, government, civil society, media, law enforcement, military, and nongovernmental/nonprofit organizations. Increasingly complex systems, including interrelated technical dimensions, are central to modern defense systems. Intelligence Engineering: Operating Beyond the Conventional provides a new framework for generating analysis, exploring how systems to system-of-systems can be harnessed both for and into the future. Intelligence engineering (IE) involves the use of scientific and technical knowledge to artfully create, operate, maintain, and dismantle complex devices, machines, structures, systems, and processes that support and/or disrupt human endeavor occurring in the intelligence context. Spanning both human and technical intelligence realms, IE includes the collection and analysis of information that is of military and/or political value, and that relates to international relations, defense, and national security. Strategic Futures, risk management across to resilience concerns, are similarly engaged.

Researchers examined past U.S. countering violent extremism and terrorism prevention efforts and explored policy options to strengthen terrorism prevention in the future. They found that current terrorism prevention capabilities are relatively limited and that there is a perceived need for federal efforts to help strengthen local capacity. However, any federal efforts will need to focus on building community trust to be successful.
