For a decade, the EU and NATO have both claimed to have a relationship purported to be a Strategic Partnership. However, this relationship is widely understood by both academics and practitioners to be problematic. Although not denying that the relationship is problematic, it is claimed here that the argument, whereby the EU and NATO simply do not cooperate, is very limited in its value. In fact, it is argued that the two organisations cooperate far more, albeit less efficiently, outside of the formal Agreed Framework for cooperation. According to the formal rules of Berlin Plus/Agreed Framework (BP/AF), the EU and NATO should not cooperate at all outside of the Bosnia Herzegovina (ALTHEA) context. This is clearly not the case. The fundamental aim of this thesis is to investigate how this cooperation - beyond the BP/AF has emerged. Above all, it asks, within a context where formal EU-NATO cooperation is ruled out, what type of cooperation is emerging? This thesis attempts to explain the creation and performance of the informal EU-NATO institutional relationship beyond Berlin Plus. This thesis, drawing on insights from historical institutionalist theory and by investigating EU-NATO cooperation in counter-piracy, Kosovo and Afghanistan, puts forward three general arguments. First, in order for informal EU-NATO cooperation to take place outside of the BP/AF, cooperation is driven spatially away from the central political tools of Brussels, towards the common operational areas and hierarchically downwards to the international staffs and, in particular, towards the operational personnel. Second, although the key assumptions of historical institutionalism (path dependency, punctuated equilibrium and critical junctures) help to explain the stasis of the EU-NATO relationship at the broad political and strategic level, a more complete understanding of the relationship is warranted. Including theoretical assumptions of incremental change helps to explain the informal cooperation that is now driving EU-NATO relations beyond Berlin Plus. Finally, this thesis makes the fundamental claim that the processes of incremental change through informal cooperation reinforce the current static formal political and strategic relationship. Events and operational necessity are driving incremental change far more than any theoretical debates about where the EU ends and NATO begins. Until events force a situation whereby both organisations must revisit the formal structures of cooperation, the static relationship will continue to exist, reinforced by sporadically releasing the political pressure valve expedited through the processes of informal cooperation. If the EU and NATO are to truly achieve a Strategic Partnership , it will stem from an existential security critical juncture and not from internal evolutionary processes.

The study of the European Security and Defence Policy (ESDP) has been dominated by various mainstream theories drawn from International Relations and European Studies. These have largely neglected the role of ideas, beliefs, values and practices regarding the use of police and military instruments, in other words, the strategic culture which shapes the security and defence policies of the European Union (EU). This strategic culture of the EU has become manifest in the way ESDP officials think about the deployment of military and police resources as well as in the way they plan ESDP missions. After introducing the concept in general terms, the thesis claims that the notion of strategic culture can be applied to the EU. Various innovative models of categorisationa re provided throughout the thesis in order to describe the state of development of EU strategic culture. An analysis of the development of the strategic culture of the EU is provided since the end of the Cold War up to the year 2007. Important developments such as the institutionalisation of ESDP and the establishment of influential policy networks are considered in detail. The study also takes into account the discourse of ESDP and questions the ideas that stem from it through interviews and questionnaires with ESDP officials. A cases tudy of the police and military missions of the EU in Bosnia Herzegovina is included in order to show how ideas regarding the use of force impact on the implementation of EU missions. In conclusion, the thesis claims that the EU has its own strategic culture which is characterised by a number of behavioural/structural elements as well as by certain ideas, values, beliefs and practices.

The purpose of this thesis is to provide a critical evaluation of the neorealist theory of international relations and its soft balancing variant through the use of case studies referring to transatlantic relations in the post-Cold War era. Each case study indicates a specific category of power. These are: i) Military - the European attempt to create a common military arm from 1991 to 2003. ii) Diplomatic - the EU's involvement in the Israeli-Palestinian conflict from 1991 to 2003. iii) Economic the EU-USA steel dispute in 2002/03. In particular, the thesis undertakes to analyse whether the EU balanced the USA in the post-Cold War period either as a result of the altered structural distribution of capabilities within the international system (unipolarity) or of a set of deliberate plans to do so. After introducing the concepts of unipolarity, hard and soft balancing, the thesis outlines three comprehensive answers that neorealist scholars have generated as to whether the USA can or cannot be balanced in the post-Cold War international system, namely the structural, the soft balancing, and the alternative structural options. Then, drawing on a defensive realist perspective, this research goes on to consider the creation of the EU as a great power in the post-Cold War era. In light of this, the thesis aims to find out whether the rise of the EU as a great power has had an impact upon unipolarity either because of structural incentives or because of a predetermination to frustrate the aggressive policies of the unipolar state. The thesis then proceeds to investigate whether throughout the case studies series the EU has balanced the USA. The case studies highlight that the EU, freed from the rigid bipolar stalemate it had been locked into during the Cold War, undertook to exert greater influence on the world stage in the post-Cold War period. To some extent the EU has accomplished this in all of the power dimensions analysed in this thesis. Nevertheless, the EU's efforts to hold sway within the international system were not aimed at addressing the relative power imbalance created by unipolarity, and there were no deliberate plans harboured by the EU to frustrate the influence of any aggressive unipolar state. Overall, this thesis found the causal logic outlined by neorealism to be convincing to the extent that the EU emerged as a great power in the post-Cold War era and had greater freedom of action under unipolarity. However, with the partial exception of the economic dimension of power, there was no persuasive evidence uncovered to support the anticipated outcome of the neorealist theoretical slant, namely that great powers tend to balance each other. Moreover, while the soft balancing claim is considered to have promise as an attempt to understand how the EU can respond to US power under unipolarity, this study did not find sufficient evidence of the EU's deliberate intentions of doing so.

Approved for public release; distribution is unlimited / In the process of the European implementation of a Common Foreign and Security Policy (CFSP) at Maastricht in December 1991 until the Franco-British declaration on European defense at Saint-MlÌ o in December 1998, the EU's European Security and Defense Policy (ESDP) etched out the initial concept of a European Pillar within the framework of NATO expressed in NATO's European Security and Defense Identity (ESDI). The Franco-British declaration at Saint- MlÌ o demonstrated the willingness of some EU member states to promote autonomous military capabilities within the EU that enables the EU to act outside of NATO's framework. The further development of ESDP led to concern among NATO officials and US diplomats regarding ESDP's potential challenging appearance to NATO. US Defense Secretary Donald Rumsfeld expressed this concern about a growing EU opposition to the transatlantic policy of alliance. In January 2003, during the Iraq Crisis, Mr. Rumsfeld labeled France and Germany as the "Old Europe". The relation of ESDP to NATO is strongly affected by the national interests of leading European actors like France and Germany. The development of ESDP as either a competitor or support arm of NATO depends on whether the French or the German approach to European security becomes dominant. / Major, German Air Force

Approved for public release, distribution is unlimited / Since 1998, the European Union (EU) has begun to develop a Common European Security and Defense Policy (ESDP), which provides a stronger role in the security and defense areas in order to become a more important actor in these fields. Since that time, the member states of the European Union have been pursuing capabilities to conduct conflict prevention and crisis management operations, with no intention of overcoming NATO's role and capabilities in the field of collective defense, but with the intention of strengthening the Union's role and influence in international politics. This thesis demonstrates that a common European Security and Defense Policy is vital for the future of the European Union. The need for a common policy is more urgent than ever because only in this manner can the European Union be strong and significant. This thesis identifies and analyzes the origins of this concept, shows how the current situation has increased that demand and explains the reasons for the establishment of ESDP. The thesis concludes with an evaluation of these ideas and policy recommendations for a member state, for Greece and for the European Union itself. / Major, Hellenic Air Force

Discourses of danger are a significant part of security and identity politics. They serve well for analysing the construction of both, security through identity politics, and identity through security policy. In this article, the declaration of the Vilnius Group of February 2003 is used as a point of departure. The author discusses the construction of state and national identities in Estonia, Latvia, and Lithuania throughout the 1990s by means of security policy, danger discourse, and mechanisms of exclusion. He argues that the replacement of Russia as a threat to Baltic security (in documents and policy manifestations) is a reflection of a relaxation of Baltic-Russian relations as well as an ingredient of the pre-accession strategy towards NATO. Political-military threats are replaced by cultural ones, while Russia, hitherto frequently represented as a concrete danger, gives way to abstractions such as „international terrorism“.

This thesis seeks to depict the German stance towards European security in the post-Cold War era. It attempts to portray the continuity and change in Germany&rsquo / s policies towards the maintenance of European security first, by specifying the differences between the Cold War and the post-Cold War era, and second, within the years after the reunification of the two German states. This is examined in the light of the main developments in the international level, the European Union (EU) level and the German domestic level. These include on the international level the War in Kosovo, the Afghanistan intervention and the Iraq War / on the European Union level the EU treaties up until the Treaty of Lisbon and the developments on the European Security and Defence Policy (ESDP) / and lastly on the German domestic level the 1994 and 2006 Wei&szlig / buch (White Paper), which are official documents published by the German Ministry of Defence. This thesis indicates the change in Germany&rsquo / s European security perception after the reunification towards a new and different sort of assertiveness. It is argued that this assertiveness invigorates within a European Germany.

By creating a common foreign policy the EU stands to maximize its international clout and leverage over the globe, in much the same fashion as it has done with its united economic policies. European integrationists imagine the EU becoming a major global power, speaking with one voice, substantially increasing its political clout. As a major power the EU could stand to become a counterbalance to the United States, stabilizing the current unipolar world system and offering a real alternative on the global scene. However, standing in the way of such pursuits is the EU member states unwillingness to give up national sovereignty, along with their own individual foreign policy interests, orientations, traditions, and histories. Achieving global superpower status is most unlikely, but the EU can still make great strides in the area of foreign affairs if it can develop some common ground to work upon. This thesis seeks to expand upon the literature discussing the European Unions foreign policy process. It seeks to clarify the issues preventing the development of meaningful foreign policy, and therefore contribute to the body of knowledge concerning the difficulties that the EU faces. By examining the recent events of the preamble to the war in Iraq, this study analyzes the CFSP as it is to date, and draws conclusion about the nature of collective decision-making within the EU. It is also valuable in its analysis of the foreign policy process and how this in turn reflects upon the wider process of European integration.

Problems of coherence and effectiveness have been repeatedly mentioned by external observers as affecting European Union (EU) external action. A theory-based explanation of this state of affairs is, however, lacking in the literature. This thesis aims to address this lacuna by focusing on a particular aspect of EU external action, the Common Foreign and Security Policy (CFSP), and by analysing CFSP actions in Bosnia and Herzegovina (BiH) throughout the period 1991-2006. Its primary goal is to determine which factors explain different degrees of coherence and effectiveness, and, in particular, whether or not, increasing CFSP institutionalisation has promoted coherence and effectiveness. After introducing the concepts of coherence and effectiveness, the thesis sketches the political and academic debate surrounding these concepts, and three key explanatory factors are singled out: interests, identities and institutions. The latter is taken as a starting point for analysis. Drawing on a historical institutionalist theory, it explores the CFSP institutionalisation and examines how the development of institutions, path dependency, unintended consequences , learning and socialisation have affected CFSP coherence and effectiveness over time. Furthermore, it aims to find out whether changes in institutions have facilitated convergence of Member States' interests regarding EU policy towards BiH, as well as the development of the EU's broader international role. The thesis then proceeds to investigate CFSP activities in BiH, analysing coherence and effectiveness in eight case studies. It concludes that CFSP institutionalisation has partially increased levels of effectiveness over the period 1991-2006. As for coherence, greater institutionalisation has resulted in some problems of coherence in the short term, but leaming has been a significant factor correcting these in the medium and long term. While path dependency has resulted in problems of coherence and effectiveness, socialisation processes have been important in facilitating consensus among the Member States. Finally, CFSP institutionalisation is seen as having had an impact on the EU's international role moving it from a civilian to a normative power, willing to resort to military instruments when necessary.
