Counterterrorism refers to the strategies and actions taken by governments and organizations to prevent, combat, and respond to terrorist activities. This includes intelligence gathering, law enforcement operations, and international cooperation to disrupt terrorist plots and networks. The goal is to protect citizens and maintain national security. Efforts in counterterrorism often involve various agencies, such as the FBI in the United States or MI5 in the United Kingdom, working together with other countries. These initiatives may also include community engagement programs aimed at preventing radicalization and promoting social cohesion to reduce the appeal of extremist ideologies.
