"The Western response to Russia’s collapse was triumphalist. It was hailed as signaling “the end of history,” the final victory of Western capitalist democracy, almost as if Russia were being instructed to revert to its pre-World War I status as a virtual economic colony of the West. NATO enlargement began at once, in violation of verbal assurances to Gorbachev that NATO forces would not move “one inch to the east” after he agreed that a unified Germany could become a NATO member—a remarkable concession, in the light of history. That discussion kept to East Germany. The possibility that NATO might expand beyond Germany was not discussed with Gorbachev, even if privately considered."
