Instead of ushering in an era of enduring peace and partnership, the end of the Cold War was followed by a decade of turmoil, with wars in the Persian Gulf, the Balkans, and Chechnya, political violence in Moscow, and controversy over the eastward expansion of NATO. The disappointments and turbulence stemmed in part from the personalities and political choices of top leaders, including the erratic and increasingly autocratic Boris Yeltsin, the skeptical and stingy responses of George H. W. Bush to the reform and collapse of the Soviet Union, and the way Bill Clinton unreservedly embraced Yeltsin while also antagonizing him by deciding to enlarge NATO and wage war against Serbia. As this chapter shows, though, American–Russian relations in the 1990s were also roiled by widely shared popular attitudes, including American triumphalist mythology about how the Cold War ended, unrealistic Russian expectations of massive US aid and respect despite Russian corruption, mismanagement, and weakness. The bright promise of the end of the Cold War was marred both by arrogant American unilateralism and by a Russian slide into depression and authoritarianism.
