Terrorism is the systematic use of terror especially as a means of coercion. At present, the International community has been unable to formulate a universally agreed, legally binding, criminal law definition of terrorism. Common definitions of terrorism refer only to those violent acts which are intended to create fear (terror), are perpetrated for an ideological goal (as opposed to a lone attack), and deliberately target or disregard the safety of non-combatants (civilians). Some definitions also include acts of unlawful violence and war. The history of terrorist organizations suggests that they do not select terrorism for its political effectiveness. Individual terrorists tend to be motivated more by a desire for social solidarity with other members of their organization than by political platforms or strategic objectives, which are often murky and undefined.
