While the previous chapter chronicled the origins of the Cold War, chapter 8 (“Consolidating the Liberal International Order”) considers its ending. It focuses in particular on the principal security component of Western order during the Cold War’s endgame, NATO. In contrast to the extraordinary transformations after World War II, the pivotal changes in international power and influence that took place between the 1989 and 1991 did not correspond with matching changes in American order preferences or, more importantly, in order outcomes. Instead, US leaders ultimately chose to stick with existing principles, maintaining continuity of the Western order in the transition from the Cold War to a post–Cold War international system. We can account for this continuity, this chapter argues, by assessing American perceptions of the lack of new any new threatening entities or forces during this critical period.
