What are the essential features of the post-Cold War world order and how is it likely to evolve? In this chapter, Nuno P. Monteiro analyzes the magnitude of the power shifts that took place around the 1989/91 watershed – between the United States and both Russia and China – and examines the ways in which the post-Cold War order relates to earlier times. Much has changed on the surface, above all the emergence of a preponderant global power, the United States. At the same time, much has also remained the same: the centrality of states, their goals and strategies, the role of material capabilities and ideology in furthering state goals, the effects of the nuclear revolution, and so on. Combining these continuities and changes, Monteiro distills the central features of world order in the post-Cold War era. He then concludes by looking at current transformations in world politics – such as the emergence of a viable alternative to the Western way of life backed by the massive capabilities of the Chinese state – and highlighting the major issues on which the future of world order hangs.

What will be the contours of the “post-post-Cold War” world? This chapter takes up that question by examining the defining international and domestic characteristics of this new age and assessing their similarities with previous eras. We begin by identifying three defining attributes of the Cold War: ideological clash, limited economic exchange, and nuclear arms racing between the American and Soviet-led blocs. Next, we explore the central feature of the post-Cold War era - namely, American primacy. We then examine the trends that have eroded primacy's material underpinnings and produced new domestic and International conditions — global power shifts, technological change, and sociopolitical fragmentation -- then project forward how those trends are likely to evolve over the next ten to fifteen years. Finally, we examine the extent to which those trends are distinct from, or continuous with, the conditions facing the United States during the Cold War and post-Cold War eras, and find that some important continuities remain even as meaningful discontinuities will disrupt existing patterns of international order. The chapter concludes by arguing that the post-post-Cold War world requires a new strategic approach for the United States — one guided by a principle of openness, rather than Cold War-style containment or post-Cold War-style liberal universalism.
