Counterterrorism refers to the strategies and actions taken by governments and organizations to prevent and respond to terrorist activities. This includes gathering intelligence, enhancing security measures, and working with international partners to disrupt terrorist networks. The goal is to protect citizens and maintain peace by addressing the root causes of terrorism and reducing the threat posed by extremist groups. Efforts in counterterrorism often involve various agencies, such as the FBI in the United States or MI5 in the United Kingdom, which work together to share information and coordinate responses. Additionally, community engagement and education play vital roles in preventing radicalization and fostering resilience against extremist ideologies.
