In this classic work, John Steinbruner argues that the time is ripe for exploration of a new theoretical perspective on the decision-making process in government. He suggests that the cybernetic theory of decision as developed in such diverse fields as information theory, mathematical logic, and behavioral psychology generates a systematic but non-rational analysis that seems to explain quite naturally decisions that are puzzling when viewed from the rational perspective. When combined with the basic understanding of human mental operations developed in cognitive psychology, the cybernetic theory of decision presents a striking picture of how decision makers deal with the intense uncertainty and fundamental value conflicts that arise in bureaucratic politics. To illustrate the advantages of using cybernetic theory, Steinbruner analyzes the issue of sharing nuclear weapons among the NATO allies.

Climate change can reasonably be expected to increase the frequency and intensity of a variety of potentially disruptive environmental events-slowly at first, but then more quickly. It is prudent to expect to be surprised by the way in which these events may cascade, or have far-reaching effects. During the coming decade, certain climate-related events will produce consequences that exceed the capacity of the affected societies or global systems to manage; these may have global security implications. Although focused on events outside the United States, Climate and Social Stress: Implications for Security Analysis recommends a range of research and policy actions to create a whole-of-government approach to increasing understanding of complex and contingent connections between climate and security, and to inform choices about adapting to and reducing vulnerability to climate change.

"At the moment, the revision of security policy and the formation of a new consensus to support it are still at an early stage of development. The idea of comprehensive security cooperation among the major military establishments to form an inclusive international security arrangement has been only barely acknowledged and is only partially developed. The basic principle of cooperation has been proclaimed in general terms in the Paris Charter issued in November of 1990. Important implementing provisions have been embodied in the Strategic Arms Reductions Talks (START), Conventional Forces in Europe (CFE), and Intermediate-Range Nuclear Forces (INF) treaties. Except for the regulation of U.S. and Commonwealth of Independent States (CIS) strategic forces, however, these arrangements apply only to the European theater and even there have not been systematically developed. The formation of a new security order requires that cooperative theaters of military engagement be systematically developed. Clearly that exercise will stretch the minds of all those whose thinking about security has been premised on confrontational methods. Nonetheless, such a stretching is unavoidable. The new security problems are driven by powerful forces, reshaping the entire international context. They impose starkly different requirements. They will deflect even the impressive momentum of U.S. military traditions. The eventual outcome is uncertain. It turns upon political debates yet to be held, consensus judgements yet to form, and events and their implications yet to unfold. Fundamental reconceptualization of security policy is a necessary step in the right direction, and it is important to get on with it. Getting on with it means defining the new concept of cooperative security, identifying the trends that motivate it, outlining its implications for practical policy action, and acknowledging its constraints. These tasks are the purpose of this essay. "

Among its many important effects, the political revolution in central Europe has provided a sharp reminder that international security is as much a state of mind as it is a physical condition. The threat of a Soviet invasion of Western Europe, long hypothesized by Western defense ministries on the basis of a perceived imbalance in inherent conventional force capability, is now acknowledged to be a practical impossibility because shifts in political alignment have been credited. In the wake of that judgement, the force deployments themselves are virtually certain to be reduced, equalized, and disengaged, thereby removing firepower advantage as a threat to international stability. Moreover, though the intrinsic connection is remote, a similar judgement seems to be affecting global strategic deployments. As strategic forces are projected to be reduced to common ceilings by mutual agreement, the fear of preemptive attacks on theoretically vulnerable land-based installations appears to be receding more rapidly than the inherent capability that originally inspired it. This relief from the narrowly focused, obsessive fears that have dominated U.S. security policy for several decades is certainly a constructive development, but unfortunately it is not comprehensively valid. For strategic forces in particular, some subtle interaction between human judgement and physical capability remain potentially dangerous, presenting a security problem that will not be resolved simply by completing the projected agenda of national weapons development and international arms control agreements. The problem arises from conceivable combinations of events that are undoubtedly improbable but unprecedentedlycatastrophic should any of them ever occur. The standards of safety that have evolved for improbable disasters of much smaller magnitudenuclear reactor meltdown, for examplehave been applied to only peacetime operations and have not been extended to the circumstances of advanced crisis or to the actual implications of combat operations. To appreciate the implications of this limitation and the dangers that emerge from it requires a substantial revision of standard perspectives on strategic security.

"In the final days of this century, the United States will need to amend the core of its foreign policy-a formidable task in a large democracy. American thinking, still grounded in post-World War II perceptions, has failed to keep pace with the demands of a changing world. New realities in the U.S. and international economies, in security conditions, and in world politics call for restructuring American foreign policy. The policy experts contributing to this volume state the process of public debate that must precede the hard political choices ahead. Barry P. Bosworth and Robert Z. Lawrence consider the ramifications of an American economy no longer an implicit source of leverage in pursuing policy objectives. William W. Kaufmann prescribes ways to preserve international commitments and ensure American security in spite of fiscally constrained defense budgets. John D. Steinbruner discusses efforts to achieve a more stable military balance. In a related chapters, Kenneth Flamm and Thomas L. McNaugher propose a redraft of American investment patterns to make the defense technology more consistent with contemporary security requirements. All of this domestic restructuring will take place within the constraints and opportunities created by recent changes in China and the Soviet Union, continued economic expansion in Japan, and persistent unrest in the Middle East. Harry Harding and Ed A. Hewett review the prospects for reform in China and the Soviet Union. Harry Harding and Edward Lincoln describe the surge in many Asian economies and the increased importance of Japan as a world power. And in the final chapter, Harold H. Saunders turns attention to the Middle East, where identifying desirable solutions continues to be far easier than finding realistic methods for achieving them. The inauguration of a new administration creates an opportunity for political debate, a new conceptual focus, and effective political consensus. Restructuring American Foreign Policy opens the debate. "

From the earliest human records, warfare has been both an organizing focus and a prime source of political motivation. Countless battles have been fought in the course of colonizing the planet, and the experience has created a legacy of military confrontation that many people consider immutable. Since preparations for war and the occasional conduct of it have been central preoccupations for virtually all the major states throughout time, it is widely assumed that the pattern is rooted in human nature and will endure indefinitely. But contemporary civilization is undergoing a monumental transformation affecting its most basic features. The combined effects of information technology, population dynamics, and the globalization of economic activity are altering some of the critical operating conditions of human societies and appear to be inducing a new pattern of interaction. Correspondingly, fundamental changes in the practice of war-or what is now more politely called international security-can be expected to follow. Principles of Global Security anticipates the major implications of this massive transformation for security policy. John D. Steinbruner, one of the nation's leading specialists on defense issues, identifies formative problems and organizing principles relating to the predictable issues of security. He examines in sequence how the configuration of nuclear and conventional forces might be affected, how the problems of communal violence and dangers of technical proliferation might be managed, and how security relationships among the major states might be altered. One of the fundamental implications of globalization in a post-cold war environment is a shift in security policy from deterrence to reassurance, from active confrontation to cooperative engagement. Without an opponent to justify preparation for large-scale traditional missions, nations must establish safer and less volatile patterns of deployment. Maintaining global security in the twenty-first century calls for a reconfiguration of basic relationships among historical opponents, as well as revisions in military practices. This visionary work will stimulate productive thinking among policymakers seeking to reshape the legacies of the cold war with a new conceptualization of international security.
