This thesis explores the Security Governance of the European Union (EU) by examiningthe relationship between the external dimension of Justice and Home Affairs (JHA) andcivilian crisis management missions. More specifically it tests the capacity of EU levelactors to project the external dimension of JHA's goals, in a coordinated and coherentfashion, into the Union's near abroad. The research 'puzzle' lies in the multi-dimensionalcharacter of the external dimension of JHA. The fact that the domains tools andcompetencies are spread within and across all three pillars of the EU make its coordinationwith civilian crisis management missions far from straightforward. The ambition to linkthe two policy domains has been expressed repeatedly by the EU in high profile strategicdocuments, such as the European Security Strategy of 2003, and the 2005 'A Strategy forthe External Dimension of JHA: Global Freedom, Security and Justice'. This thesisendeavours to tests the EU's performance in governing the external dimension of JHA andthe need to links its goals with those of civilian crisis management missions. It does this bytaking three civilian crisis management missions recently projected into the EU's milieu,with mandates related to security sector reform and JHA. The missions selected forcomparison are: Proxima launched in 2003 in Macedonia; EU Border Assistance Missionto Moldova and Ukraine launched in 2005; and finally, EULEX Kosovo launched in 2008.These missions are selected to serve as prime test cases for the interface between JHA andcivilian crisis management missions, covering a time period that will allow for anexamination of continuity and change in foreign and security policy at the EU level.
