This timely treatise introduces an innovative prevention/preparedness model for cities to address and counter terrorist threats and events. It offers theoretical background, mixed-method research, and tools for creating a resilience-based response to terrorism, as opposed to the security-based frameworks commonly in use worldwide. The extended example of Milan as a resilient-healthy city pinpoints sociological, political, and economic factors that contribute to terror risk, and outlines how law enforcement and emergency management professionals can adopt more proactive measures. From these observations and findings, the author also makes recommendations for the professional training and city planning sectors to address preparedness issues, and for community inclusion programs to deter criminal activities in at-risk youth.
