The wave theory refers to the “Four Waves of Modern Terrorism,” which was published in 2004 by David C. Rapoport, Professor Emeritus at the University of California Los Angeles and a founding editor of the journal Terrorism & Political Violence. Wave theory made a unique contribution to the study of terrorism by positing a generational model that linked contemporaneous global terrorist groups based on their shared characteristics of ideology/theology, strategy/tactics, and visions for the future. Although wave theory is focused on the modern period, from the late 19th century to the present day, it is built on a thorough grounding of the history of terrorism, which dates from the 1st century
Women are playing an increasingly significant role in terrorism. As men are progressively targeted by security personnel, using female operatives provides terrorist organizations with a “win-win” scenario; if security forces avoid invasively searching women for fear of outraging the local conservative population (based on social norms of women’s modesty and the honor code), women are the ideal stealth operatives. If security personnel are too aggressive in searching women, they aid terrorist recruitment by outraging the men in that society and providing the terrorists with propaganda that “our women” are being violated. In most conflicts, women remain an untapped resource. Recruiting women allows terrorist organizations to access an additional 50% of the population. Female attacks generate greater media attention than those conducted by men. This is especially relevant when media attention is one of the terrorists’ main objectives. Although women’s involvement in terrorist and extremist activities is not a recent development, their presence as frontline activists, propagandists, and recruiters is increasing around the globe.
