In June 2017, the paper on "The EU Global Strategy and the Prospects of European Defence Integration" by Professor OHN Dae Won was published on the Journal of European Union Studies, vol. 46. 

The Common Security and Defence Policy(CSDP) has always been a very important and sensitive issue to the Member States(MS) of the EU that touches the core of their national sovereignty. The Maastricht Treaty included provisions for a long-term vision for a European common defence policy, designed to achieve common defence in the long term. The lack of mutual trust and political will among the MS, however, has long remained the main obstacle against such a development. During the last few years, there have taken place tremendous changes in the CSDP since the launch of the EU Global Strategy(EUGS) in late June 2016. These changes included the establishment of the European Defence Fund(EDF) and other important plans for the strengthening of the CSDP. 

This paper deals with the background and processes of these developments and their implications for European defence integration. It is understood that such moves have been aimed at reinforcing the unity and coherence of the Union amidst very difficult internal and external circumstances through strengthening the CSDP and facilitating defence integration. These will likely cause enormous changes in the CSDP in the coming future, gradually threatening to undermine the foundation of the longstanding tradition of state-centric approach towards security and defence in Europe to a great extent. There, however, will arise enormous constraints and challenges that the EU and the MS should overcome before they achieve their long-time dream of the European Defence Union (EDU), which would include surging Euroscepticism and the rise of ultra-right nationalist forces in Europe.
