Question

Terrorism is the use of violence and threats of violence against non-state actors and/or from clandestine groups with political, religious, and ideological intentions aimed at inspiring fear beyond mere threat. The most significant features of terrorism and ones which differentiate it from other forms of violence are its political and ideological objectives, use of violence against civilian and/or iconic targets with the strategic purpose of inspiring fear and undermining confidence and/or authority of the government in a wider audience beyond mere threat. The use of asymmetrical and clandestine tactics with the purpose of disseminating information about the attack also helps in distinguishing terrorism from other violence. The examples of terrorist acts include the bombings of the World Trade Towers on September 11th carried out by al-Qaeda, which targeted U.S. economic and military power with political and ideological intentions of inspiring fear and influence and causing policy change, while others include domestic terrorism such as the Oklahoma City bombings of 1995 with political and ideological intentions of inspiring fear and influence. Other groups such as insurgent and guerrilla warfare terrorists often merge with other terrorist groups in cases where they involve violence against civilians with purposes of inspiring coercion and change of politics while others such as mass shootings with no political ideologies fall under criminal violence. Another reason why terrorism is significantly different from other violence is due to its lack of universally accepted definitions.

Answer 1

Do you want this rewritten for clarity, shortened into a single definition, expanded with sources, or turned into a formal academic paragraph? I can do any of those. Meanwhile, here are quick improvements you can use.

Polished paragraph (clearer, tighter):
Terrorism is the deliberate use — or threatened use — of violence by nonstate actors or clandestine groups to achieve political, ideological, or religious goals by creating fear that extends beyond the immediate victims. It is distinguished from other forms of violence by (1) explicitly political or ideological objectives, (2) attacks on civilians or symbolic/strategic targets intended to influence a wider audience, (3) asymmetrical and clandestine tactics designed to attract publicity and spread the perpetrators’ message, and (4) a strategic aim of undermining public confidence or state authority. Examples include al-Qaeda’s September 11 attacks, intended to harm U.S. economic and military power and to influence policy, and the 1995 Oklahoma City bombing, a domestic political act of terror. Acts of mass criminal violence without political intent are not terrorism, and the boundary between terrorism, insurgency, and guerrilla warfare can blur when groups use violence against civilians to coerce political change. Definitions of terrorism remain contested and vary by legal, political, and scholarly contexts.

One-sentence definition:
Terrorism is the use or threat of violence by nonstate or clandestine actors to achieve political, ideological, or religious aims by creating fear and influencing a wider audience beyond the immediate victims.

Key distinguishing features (bullet form):
- Political, ideological, or religious motive (not merely personal or criminal).
- Targeting civilians and/or symbolic targets to influence opinion or policy.
- Asymmetrical, clandestine tactics often intended to garner publicity.
- Strategic goal of instilling fear and undermining confidence in institutions.
- Contested and context-dependent definitions; overlaps exist with insurgency and state violence.

If you’d like, I can: cite academic definitions (e.g., Schmid, Hoffman), shorten further, adapt this for a paper, or convert it into a legal-style definition. Which would you prefer?
