Counter-terrorism 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 networks and protect citizens from attacks. Efforts in counter-terrorism often involve various agencies, such as the FBI in the United States or MI5 in the United Kingdom, working together to share information and resources. Additionally, counter-terrorism can include community engagement programs aimed at preventing radicalization and promoting social cohesion among diverse populations.
