The fall of the Berlin Wall inspired a variety of scholars to speculate about why the Cold War came to such an abrupt and shocking end, why no school of thought anticipated its demise, and what the event meant for international relations theory. A set of articles simultaneously emerged purporting to identify the most salient aspects of the new system, structural and otherwise, and to anticipate the direction in which it was heading. This paper begins a re-examination of some of those predictions, using the evidence that has accumulated over the decade and a half since the collapse of bipolarity to evaluate how early visions of the post-Cold War international system matched events that followed. In all the main areas of contention between neorealist and constructivist predictions -over balancing, the rise of multipolarity, and conflict -constructivism, with its emphasis on the role of ideas and norms in state behavior, has proven more prescient.
