The topic of Russo-European Union (EU) relations is one of the most important security issues in Europe and Russia because this relationship will help determine the security situation throughout Eastern and Central Europe well into the future. The course of this relationship also will influence in large measure the extent to which Russia moves toward realizing its historic European vocation and its proclaimed ambition to become a democracy. On the other side, the relationship will influence significantly the capability of the EU to function effectively as a union of European states, possibly including Russia, and other European members of the Commonwealth of Independent States like Ukraine, Belarus, and Georgia. Admittedly this relationship is in a rather precarious state. But it is essential that policymakers and analysts understand what the problems are that have impeded Russia's integration with Europe if we and they are to overcome these obstacles.
