ABSTRACT
What are the conditions of and possibilities for global security in the twentyfirst century? Before answering this question concretely, first I have to tackle the prevailing theories of peace and security and build a conceptual framework for constructing explanatory models and scenarios of future possibilities. What, then, are the dominant theories of peace and security in the early twenty-first century? Can we confidently maintain that we, the academic community of researchers working on peace, conflicts and security, have genuinely learnt something from the late twentieth-century peace and security studies? How widely accepted are the prevailing theories, and how strong is the evidence for them?
