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.
United States and state terrorism
In "State terrorism and the United States" Frederick F. Gareau writes that the intent of terrorism is to intimidate or coerce both targeted groups and larger sectors of society that share or could be led to share the values of targeted groups by causing them "intense fear, anxiety, apprehension, panic, dread and/or horror". The objective of terrorism against the state is to force governments to change their policies, to overthrow governments or even to destroy the state. The objective of state terrorism is to eliminate people who are considered to be actual or potential enemies, and to discourage those actual or potential enemies who are not eliminated.
