Terrorism
Terrorist acts frequently have a political purpose. Some official, governmental definitions of terrorism use the criterion of the illegitimacy or unlawfulness of the act. to distinguish between actions authorized by a government (and thus "lawful") and those of other actors, including individuals and small groups. For example, carrying out a strategic bombing on an enemy city, which is designed to affect civilian support for a cause, would not be considered terrorism if it were authorized by a government. This criterion is inherently problematic and is not universally accepted, because: it denies the existence of state terrorism. An associated term is violent non-state actor.
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.
