IntroductionThis article will talk about three different types of terrorism. A history of each type will be provided to understand motivations and objectives. The first type that will be discussed is religious terrorism. The second type that will be discussed is suicide terrorism. The third and final type that will be discussed is nationalist terrorism. Each type of terrorism has distinct differences in its goals, motivations, strategy, use of violence, etc. However, this article will primarily focus on the difference between the tactics and/or strategy of each type.1. Religious: Background Religious terrorism is generally carried out based on motivations, objectives and beliefs of some religious influence. The religion that appears to be the most radical and involves the most terrorist activity is Islam. A very small group of Muslims is behind almost all religious terrorist attacks. An example of one of the most radical, dangerous and powerful religious terrorist groups would be Al-Qaeda. The history of Al-Qaeda began during the Cold War. Western countries, such as the United States, and its allies supported militant units within Islam to fight the Soviet Union. The United States formed an alliance with the Pakistan Interservice Intelligence Agency (ISI) (White, 2012). The ISI is the equivalent of the CIA, the American intelligence agency. The ISI, alongside the United States, began training and arming mujahideen (sacred warriors) to fight the Soviet Union. In 1979, the Afghan mujahideen and Saudi Arabia fought the Soviet Union's invasion of Afghanistan (White, 2012). The United States supported the Afghan Mujahideen and all other forms of Islam to fight the Soviet Union. The United States has developed a subset of documents: a preliminary theoretical synthesis and an illustrative case study. Studies in Conflict and Terrorism 29: 165-185. Scheuer, Michael. 2002.
