In this title, terrorism, sabotage, and subversion are analyzed to challenge the dominant views that a 'new conflict' is now posing unprecedented threats to U.S. homeland security. Since 9/11, the dominant view is that we have entered an era of 'new conflict' in which technology has empowered non-state actors who now pose unprecedented and unmanageable threats to U.S. national security. This unique work studies a range of threats, from homegrown and foreign terrorism to the possibility of cyber- or Chinese sabotage and fears of religious subversion to challenge every aspects of this 'new conflict' argument and expose its underlying exaggerations and misunderstandings. Examining such issues as political violence, the role of religion in terrorism, the impact of technology, and the political aspects of homeland security, this unique survey demonstrates how such activities as terrorism are limited by their clandestine nature. It also addresses why we need to switch our strategic focus and increase the role citizens have in dealing with such threats. This historically informed and critical analysis fills a void in the debates on the threats and conflicts that the U.S. confronts at home and abroad and will appeal to anyone interested in national security and terrorism.
