The chapters in this volume were solicited in an effort to update the forecaster's art in the realm of world politics, now that the advent of the nuclear age leaves little margin for error. The contributors examine war, interstate conflicts, nuclear proliferation, domestic political conflict, and international political conflict. 'The articles are, without exception, coherent, articulate, methodologically sophisticated and well-substantiated.' -- Millenium 'This is a useful addition to the rapidly growing literature on the statistical analysis of the international system.' -- Political Studies, June 1982
