The Credibility of European Union Military Operations’ Deterrence Postures

Abstract

ABSTRACTSince 2003, the European Union (EU) has launched eight military operations with an executive mandate in the framework of its European (now Common) Security and Defence Policy (ESDP/CSDP), all of which have utilized deterrence to fulfil their missions. Some have done so implicitly by having a mission that requires them to keep certain actors from doing something unwanted, whilst others have done so explicitly by having deterrence clearly mentioned as one of their core tasks in their mandates. Despite this, deterrence in the context of CSDP has been an almost totally neglected subject in the academic literature. Furthermore, the EU itself has tended to take the deterrence effect of CSDP operations for granted, which is dangerous because it may blind it to potential problems that may in fact be undermining their credibility. This article seeks to launch a more focused discussion on deterrence in the context of EU security policy by analysing the credibility of CSDP operations’ deterrence postures. Based on findings from case studies on operations Althea and Atalanta, it argues that CSDP operations’ deterrence postures lack credibility because they have insufficient resources for taking care of their deterrence tasks. Furthermore, they do not communicate threats effectively.
