History
Counterterrorist capabilities expanded during the late twentieth century as governments responded to a perceived rise in terrorist activity. After the September 11 attacks in 2001, Western governments made counterterrorism a central national‑security priority, introducing major institutional reforms, increasing international cooperation, and adopting new operational approaches such as red team analysis and a wider range of preventive measures.
