Successful eastward enlargement of the EU will be critical to ensuring stability and prosperity for post-Cold War Europe. But enlargement raises difficult issues for the EU and the applicant countries of central and eastern Europe. Is the EU capable of reforming its institutions and policies to cope with 25 or more members? Which central and east Europeans will join, and when? How can we ensure that enlargement brings the economic and security benefits expected of it?This comprehensive study examines in detail the political, economic and security implications of eastward enlargement for both East and West. The authors present new analyses of the policy issues including the EU budget and pre-accession strategy and of the economic integration likely before and after accession.Based on an extensive series of interviews with key ministers, diplomats, policy-makers, academics and journalists across Europe, this study also provides an informed overview of expectations and attitudes towards enlargement within the EU and in the applicant countries.
