Neil Livingstone said this quote

“ The term terrorism is widely misused. It is utilized in its generic sense as a form of shorthand by governments and the media and is applied to a variety of acts and occurrences that approximate terrorism in form but not in substance or, worse yet, that have no real resemblance to terrorism at all. Terrorism, if nothing else, is violence, or threats of violence, but it is not mindless violence, as some observers have charged. Usually, when employed in a political context, it represents a calculated series of actions designed to intimidate and sow fear through-out a target population in an effort to produce a pervasive atmosphere of insecurity, a widespread condition of anxiety. A terrorist campaign that causes a significant threshold of fear among the target population may achieve its aims. In some instances, terrorism is potentially a more effective, especially from a cost-benefit perspective, strategy that conventional or guerrilla warfare, however, the goal of terrorism is not to destroy the opposing side but instead to break its will and force it to capitulate. ”
