From the
Terrorism Research Center:
There is no single, universally accepted definition of terrorism. There are many reasons for this (not the least of which is the cliche "one man's terrorist is another's freedom fighter"). Even different agencies of the US government have different working definitions. Most definitions usually have common elements, though, oriented around terrorism as the systematic use of physical violence--actual or threatened--against non-combatants but with an audience broader than the immediate victims in mind, to create a general climate of fear in a target population, in order to effect some kind of political and/or social change.
Terrorism by nature is difficult to define. Acts of terrorism conjure emotional responses in the victims (those hurt by the violence and those affected by the fear) as well as in the practioners. Even the U.S. government cannot agree on one single definition. The old adage, "One man's terrorist is another man's freedom fighter" is still alive and well. Listed below are several definitions of terrorism. For the purposes of the Terrorism Research Center, we have adopted the definition used by the Federal Bureau of Investigation.
