Warfare has long been defined by nations who could design, develop, and field the most exquisite and most destructive forces either through deterrence or brute force. However, the paradigm shifts that have occurred in recent decades including Cyber, Space, and now most prominently, the Cognitive domain, offer to challenge this long-held status quo. The Havana Syndrome is a defining work for all security and intelligence professionals. Dr. Krishnan's research into the paradigm shift of conflict is an essential study for students and a must-read for planners and practitioners.

One of the nation's pioneering scholars of neurowarfare, Armin Krishnan delivers a much-needed deep investigation of the Havana Syndrome, the rash of concussion-like injuries suffered by President Obama's last diplomats in Cuba. The symptoms among the embassy team erupted, without warning, not long after normalization of relations with the United States and shortly before collapse of American diplomacy with Havana's realignment toward Russia. In the fast-paced style of a detective thriller, Krishnan supplies the circumstantial evidence, the scientific explanation, and the broader national security implications of technologically feasible directed energy weapons in the hands of America's adversaries.
