The authors of this collection combine different national and institutional perspectives. They cover a broad range of subjects: new threats to Europe’s security, the advantages and disadvantages of the present security architecture in Europe, the problem of nuclear weapons and their control, the options for enlargement and partnership for peace, the shifts in Europeans’ public opinion about security matters, and the prospects for a European defence industry. This collection provides an incomparable synthesis of some of the most crucial problems for the emergence of Europe as an independent actor in international politics.
