The fall of the Ukrainian government and its replacement with one that appears to be oriented toward the West represents a major defeat for the Russian Federation. After the collapse of the Soviet Union, Russia accepted the reality that the former Eastern European satellite states would be absorbed into the Western economic and political systems. Moscow claims to have been assured that former Soviet republics would be left as a neutral buffer zone and not absorbed. Washington and others have disputed that this was promised. In any case, it was rendered meaningless when the Baltic states were admitted to NATO and the European Union. The result was that NATO, which had been almost 1,600 kilometers (1,000 miles) from St. Petersburg, was now less than approximately 160 kilometers away.
