Global security – in the broadest sense of how we understand, manage, and better an endangered world – cuts across and encompasses many other security issues. Nation-states are beset by new global forces (WMDs, panoptic surveillance, and international regimes), transborder flows (financial, population, environmental, and viral) and complex networks (media, criminal, and terrorist). The ubiquity and velocity of interconnected global events further undermine state-centric efforts to manage global security. Varying in identity, interests, and strength, new global actors - ranging from private security forces to fundamentalist terrorists to transnational criminals to anti-globalisation activists - increasingly compete and gain advantage through networks and non-governmental organizations. Motivated by normative beliefs and enhanced by global media, a diverse group of actors are challenging the monopoly of violence, legitimacy, and information asserted by states.
Any response to security issues involving the oceans, atmosphere and space must take a global perspective and engage in a global response. Such security issues can no longer be confined to a single domain (the individual, state, or system), nor comprehended by a single field of study (traditionally, political science and/or international relations). Exceeding comprehension and management by single actors, disciplines, or beliefs, these global security issues require a transnational, transdisciplinary, and transmedia approach.
