Terrorism is defined as the unlawful use of violence against people or property to intimidate or coerce a government for political or social goals. It is a tactic that has been used throughout history to make a point through instilling fear psychologically. There are different types of terrorist groups and motives, and terrorism can involve the use of explosives, firearms, or biological, chemical, and nuclear materials to carry out attacks. While terrorism poses risks, preventing it involves reducing root causes like cultural misunderstandings, promoting human rights, and establishing surveillance and protective systems.
