There are different forms of terrorist organizations in modern history. One of the most interesting types of terrorist organizations are ethno-nationalist/separatist terrorist groups. These types of terrorist groups consist of organizations such as Fatah, IRA, PKK and Tamil Tigers. Ethno-nationalist/separatist terrorism is “the use of terrorism by a sub-state, ethnic, or national group to alter its access to state power” (Kilroy, 2008, p. 180). Groups of this nature are different from any other type of terrorist group in the sense that in most cases they have a support base; these groups generally have a historical connection. The strength of ethno-nationalist/separatist terrorism is that it appeals to others through ethnicity, making it easier for them to recruit, blend in and use violence. One organization worth touching upon when discussing this topic is the modern day Tamil Tigers. The Tamil Tigers of Sri Lanka are structured with a hierarchical state formed in Sri Lanka during the year 1975. During the mid-1900s the Tamils ​​became the target of revolts, and began to demand an organization that would protect their rights; this group promised to form its own separate state. Since their creation they have continued to make all attempts to separate from the country. The Tamil Tigers, just like other terrorist groups, have attacked public buildings and transport throughout the area. The Tigers also use similar tactics to other terrorist classifications such as religion and ideological organizations, carrying out attacks with female suicide bombers and recruiting younger children; as the Tigers developed, so did their tactics, leading to the creation of the suicide vest. So far in their history the LTTE has...half the card...and doesn't have to worry about interference from the Sri Lankan government. Reference Bishnoi, B. (n.d.).
