ZEI Discussion Paper C 274 / 2022

Supranational und zukunftsoffen. by Ludger Kühnhardt, Paderborn: Brill Fink, 2022

The Russian invasion in Ukraine has destroyed the illusions of a collective security architecture in Europe and globally, but has also strengthened resilience and defense in EU and NATO. The Russian dictatorship, led by secret services and increasingly totalitarian in nature, has closed the country towards Europe and reinforced its Eurasian orientation. In this ZEI Discussion Paper, ZEI Director Prof. Ludger Kühnhardt is assessing possible options for Russia and subsequent implications for the European Union and for Ukraine, including on matters related to membership in EU and NATO. Kühnhardt also analyses possible scenarios for an armistice which are more likely in coming years than a comprehensive and guaranteed peace accord.

ZEI Discussion Paper C 273 / 2022

The Conference on the Future of Europe - The Closing of an Unprecedented Citizen Participation Process

Along with the financial and economic threat of the sovereign debt crisis in the Eurozone from 2009 onwards, the crisis also posed a threat to the social acceptance of the European Union. The EU's ability to solve problems was at times strongly doubted by large parts of the public, which called into question the core of the common integration project. This paper reviews the stability and efficiency of the EU for this period and analyses stabilising and destabilising factors. It focuses on the input and output dimensions of the Union's legitimacy during the crisis and their influence on the EU's legitimacy level, which is empirically tested with the help of Eurobarometer data.

Das politische Denken der Europäischen Union

Supranational und zukunftsoffen. by Ludger Kühnhardt, Paderborn: Brill Fink, 2022

The European Union should be based on the idea of European sovereignty, as French President Emmanuel Macron designed the future of the EU in 2017. The concept of European sovereignty connects questions of political thought with the internal order and the global political strategy of the EU. From a historical perspective, modern political thought has evolved around the concept of the state. However, ancient roots of political thought indicate that fundamental questions of political order were already reflected in a context prior to the evolution of the modern state. Important concepts of political philosophy emerged in ancient Greek and Roman history that continue to have an impact today. Against this background, this textbook Ludger Kühnhardt discusses in this innovative text book whether and how political thinking can also generate its own concepts and reflections in a supranational context, and especially in the European Union.
