The development of a European security architecture comprising NATO, the EU, WEU, and the OSCE exemplifies the redefinition of Western values and institutions in the post-Cold War era. Gülnur Aybet examines the precedents for legitimate intervention in upholding democracy, free markets, and human rights in the post-Cold war era from the perspectives of international law and Gramscian-derived concepts of legitimacy. The author also focuses on the acceptance of military power by civil society.
