Tactics of terrorism
Suicide terrorism is the most aggressive form of terrorism, pursuing coercion even at the expense of losing support among terrorists' own community. What distinguishes a suicide terrorist is that the attacker does not expect to survive a mission and often employs a method of attack that requires the attacker's death in order to succeed (such as planting a car bomb, wearing a suicide vest, or ramming an airplane into a building). In essence, a suicide terrorist kills others at the same time that he kills himself. Usually these tactics are used for a demonstrative purposes or to targeted assassinations. In most cases though, they target to kill a large number of people. Thus, while coercion is an element in all terrorism, coercion is the paramount objective of suicide terrorism.
Political violence
While there lacks a concrete definition of terrorism, the United States Department of Defense however defines terrorism as, "the calculated use of unlawful violence or threat of unlawful violence to inculcate fear; intended to coerce or to intimidate governments or societies in the pursuit of goals that are generally political, religious, or ideological." What is and is not considered terrorism is itself a controversial political question, as states have often used the label of terrorism to exclusively demonize the actions of their enemies while obscuring "legal" violence administered by the state (e.g. The Troubles, CPP–NPA–NDF rebellion, 2014 Israel–Gaza conflict).
