In 1995, in his review of Matlock’s memoir, titled Autopsy on an Empire, Kennan wrote: “I find it hard to think of any event more strange and startling, and at first glance more inexplicable, than the sudden and total disintegration and disappearance from the international scene, primarily in the years 1987 through 1991, of the great power known successively as the Russian Empire and the Soviet Union.” Kennan referred to the fall of previous empires as gradual. That of the Soviet Union was not. “How then to explain the extreme abruptness, the sharp quick ending, and not least the relative bloodlessness with which the great Soviet Empire came to an end in the four years in question, bearing with it those attributes of the earlier Russian Empire which it had contrived to incorporate into itself?” Kennan asked himself and his readers.
Was the Soviet experience unique? We can start by considering the British Empire, the most powerful such institution of the modern era, which offered the Russians a Commonwealth model for opting out of a traditional imperial project. British imperial disentanglement was gradual indeed. It began, arguably, with the eighteenth-century American Revolution, followed by slowly developing autonomism in the dominions of Canada, Australia, and New Zealand in the nineteenth and twentieth centuries. Attempts to crush South African and Irish movements for independence proved unsuccessful in the wake of World War I; in the decades after World War II Britain withdrew from India and subsequently from its African colonies.

To the surprise and relief of many, the Russians, led by Boris Yeltsin, refused to follow in the footsteps of the Serbs, who turned the former Yugoslav army into an instrument of Serbian aggrandizement and then of genocide. Nor did the Russians cling to the Soviet republics that Russia had dominated, as the French and Belgians did to their former colonies. Instead, the Russians seem to have taken a page from the dissolution of the Portuguese empire. Both empires ceased to exist as a result of relatively peaceful revolutions that took place in their capitals, where reformers tried to dismantle authoritarian government and initiate political, economic, and social reforms. In both countries, the existence of empire was an obstacle to such reforms.
Boris Yeltsin and his advisers sought to implement their reforms in Russia, not in the Soviet Union, where Gorbachev’s efforts to democratize the system were opposed by the conservatively minded communist elites that controlled most of the Soviet republics. To free his Russian reformers from the limitations imposed on them by Gorbachev’s vacillating political center, which was stymied by competing pro- and anti-reform factions, Yeltsin allied himself with pro-democratic reformers in the Baltic states and pro–status quo elites in Central Asia, all in an effort to undermine existing Soviet institutions. Yeltsin did not intend to subvert the Soviet Union in the process, but once the disintegration that he helped to set off developed a momentum of its own, he went along. His main political rival, Mikhail Gorbachev, and the Soviet Union itself were swept away as a result.
Keeping the secessionist republics under Russian control by military force was an unlikely policy choice for other reasons as well. One of them was the enormous political, ideological, and economic influence that the United States wielded over the Soviet Union at this time, as well as the place that America occupied in the imagination of Soviet-era reformers, from Gorbachev to Yeltsin and beyond. Washington did not want the republics to fight one another, fearing the possibility of a “Yugoslavia with nukes”—a scenario that Gorbachev never tired of raising in his conversations with President George H. W. Bush.
The Russian president was prepared to use force against autonomous republics within the Russian Federation if they should attempt to secede, but not against similar aspirations of Union republics such as Ukraine. Moreover, the Soviet Army was short of resources, and Russians serving in it were not eager to fight.
