The EU is to-day at a crossroad: either it becomes a great supranational union or it goes back to being an array of separate independent states. Alberto Martinelli and Alessandro Cavalli draw a grand fresco of the society in which the European Union is taking shape. Long term social and cultural trends and main current developments in economics and politics are synthetically outlined. Key questions of identity and nationalism, immigration and inequality, welfare and economic governance, are thoroughly analysed. Main cleavages, conflicts of interest and different visions of member states, as well as institutional reforms and crisis management strategies are critically discussed. A detailed proposal for advancing the process of political integration concludes the volume.
