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.[4] 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.[4]
The word "terrorism" is politically and emotionally charged,[5] and this greatly compounds the difficulty of providing a precise definition. Studies have found over 100 definitions of “terrorism”.[6][7] The concept of terrorism may itself be controversial as it is often used by state authorities to delegitimize political or other opponents,[8] and potentially legitimize the state's own use of armed force against opponents (such use of force may itself be described as "terror" by opponents of the state.).[8][9] A less politically and emotionally charged, and more easily definable, term is violent non-state actor[10] (though the semantic scope of this term includes not only "terrorists," while excluding some individuals or groups who have previously been described as "terrorists").[citation needed]
Terrorism has been practiced by a broad array of political organizations for furthering their objectives. It has been practiced by both right-wing and left-wing political parties, nationalistic groups, religious groups, revolutionaries, and ruling governments.[11] One
