Ever since the end of the Second World War, most Europeans have felt fortunate to have lived through the longest period of relative peace ever experienced on the continent. Some now take this for granted. Is their sense of security realistic? Security is no longer perceived not only as the absence of war. It now also includes development, freedom, and justice, all part of a comprehensive concept of security. This book bridges a vital gap between the academic literature, publications of think tanks and EU documents. It gives structure to a comprehensive set of security issues facing Europe in the era of globalization and renewed security threats after the Cold War.Together with the website www.lelundin.org, structured as the book,it provides vital links between theory and actual cases in real time.The author, currently Distinguished Associate Fellow at Sipri, has anextensive experience as a security policy practitioner inside the EU institutions and as a national diplomat working with a number of international organisations.
