The purpose of the paper is to analyse the implications of decision-making differentiation for EU's security actorness. The change in the post-Cold War security environment (opportunity) favoured the explicitness of the (pillarised) security actorness of the European Union. Following the 9/11 attacks, the EU adopted an ambitious security approach that confirmed four interconnected dynamics: expansion of the security agenda, externalisation of internal security cooperation, internalisation of Common Security Defence Policy, and cross-pillarisation. It was an up-grade for the assertion of the European Union as a comprehensive and multi-functional security actor, endowed with autonomy, capability and presence. The comprehensive approach combined with a global (reach) ambition impose unique requirements on EU. A major challenge to EU's security actorness is decision-making differentiation in the security domain. With the entry into force of the Lisbon Treaty, the EU acquired legal personality, enabling it to conclude treaties and to assume external representation. This also means that, for the first time, external and internal security policies evolve in the framework of an International Organisation. The Treaty also overcame pillarisation, introduced changes in the continued search for the Union's external coherence and demonstrated the dynamism of the policies of the former second and third pillars. However, the changes that were introduced denote a constructive ambiguity patent in the existence of provisions enabling a comprehensive action, on the one hand, and of a hidden pillarisation, on the other hand, aggravated by the absence of an explicit concern with the coherence between the external and internal dimensions of security (the missing link).
