Events in Ukraine demonstrate people’s willingness to take up arms, fight, and do all that is necessary to protect themselves, their families, communities, and country. When states fail to provide security, individuals step forward and security networks develop. Pictures of men accompanying loved ones to a safe border then returning to the fight provide compelling evidence of people’s willingness to protect what is theirs; physically, mentally, and spiritually. The development of new technologies, energy sources, and Artificial Intelligence (AI), etc. may have make daily life a bit easier, but they have done little to change people’s desire to live freely, safely, and securely. Comfort alone is not good enough for a meaningful life. Freedom is. Ukraine is resilience in action and the conflict provides a laboratory for the study and advancement of individual resilience and Open Security in the 3rd Millennium. Open Security is all-of-society defense against all possible threats, internal and external, to Human Security. Open Security is self-organizing and resists formal coordination, command, and control. A way of thinking of Open Security is as a living organism. Biology, not management, explains Open Security systems.
