Dissolution: Sovereignty and the Breakup of the Soviet Union
Stop for a moment and ask not simply why the Soviet Union broke up, but why it fractured into 15 pieces, rather than many more, corresponding, say, to the country's vast number of ethnic, or religious, or linguistic groups. Walker's answer relies on the concept of sovereignty, and specifically on the peculiar institutional and normative force flowing from "ethnic federalism." He reminds the reader with skillfully reconstructed detail of the intricate and delicate emendations of "sovereignty" already under way in Moscow and the republics before the collapse. He also notes that the only postsocialist regimes to come apart at the seams were "ethnic federations" -- the Soviet Union, Czechoslovakia, and Yugoslavia. Walker is not suggesting that federalism caused the collapse of the Soviet Union; only that it provided leverage for those who wanted independence, a "supply-source" of independence for those who did not, and a framework within which the outside world could manage the unexpected.

Gorbachev's new thinking is based on the belief that military power is not the only way to national security, and that there is a link between national and mutual security.

Notes how the ideas underpinning the foreign policy revolution have existed for the last decade, and how the evidence suggests that the change is genuine.
