The document discusses proactive counter-terrorism strategies for the 21st century. It outlines that terrorist organizations now have greater capabilities due to technology and state support. It recommends acquiring real-time intelligence through infiltration, improving counter-surveillance to detect target casing, and strengthening physical barriers. Implementing these preventative measures can thwart attacks before they occur by identifying threats, monitoring terrorist activities, and securing vulnerable areas. The presentation argues this proactive approach is needed to replace reactive responses and better ensure public safety.
