The thawing of the Cold War has brought new concerns over the nature of European security to the fore and uncovered major differences in the approaches of individual states to changed circumstances. This book aims to clarify the options for a new European security order and contribute to the growing debate. It adopts a medium-term analytical approach and uses a three-tier format, covering the nature and structure of security and the security implications of Europe's resurgent nationalism; security strategy, with particular reference to the NATO perspective and to the European Community; and the distinctive security concerns of individual states. It looks at both Eastern and Western Europe and at the Soviet Union and it analyses the role of the United States in European security.
