Therefore, it is now, after a few decades, a good moment to look critically at what has been achieved in this sector of EU defence cooperation. With this reason, this thesis will approach the question, why do the member states want defence integration to happen in smaller groups? This question can be split in multiple sub-questions. Firstly, could reaction of the member states be out of discontent of how cooperation is functioning on a EU-level? Secondly, does the EU allow the member states to continue in smaller groups, instead of moving forward as a Union? These question will be approached by using a variety of documents. For example, not only the EU perspective but also the national interests of member states and the vision of experts on defence integration should be taken into consideration as well as useful sources for this thesis. Furthermore by looking at theories of defence integration in the EU, such as, Institutionalism, constructivism and realist theory, this thesis will try to find the motives for defence integration. Using the patterns of the theory will make it easier to analyse and compare the cases that will be included in this thesis. The three selected cases are from a different scale. From cooperation on a Union-level to bilateral cooperation and integration. As a result, this thesis has to add additional information and perspectives on the integration of defence within the EU.Show less
