Connecting Intelligence and Theory: Intelligence Liaison and International Relations

Intelligence liaison increased exponentially during the so-called ‘War on Terror’. Today it continues as the most significant dimension of intelligence, including impacting on accountability and oversight considerations. Nevertheless, the intelligence liaison phenomenon remains largely under-studied and substantially under-theorized. In this article, preliminary suggestions are offered concerning how this dearth of theory can be addressed. Firstly, the relevance of international relations theory and other bodies of theory, together with significant approaches concerning how international relations – extending to how intelligence and intelligence-related phenomena (such as, in this article, intelligence co-operation) – can be studied, are explored. These theories, and equally, approaches, are arguably most appropriate when deployed in an arrangement of ‘complex co-existence plurality’ across the different interrelated levels of experience and analysis, and they offer more effective explanations when intelligence liaison is disaggregated into at least eight systemic attributes or variables. More broadly, the suggestion that international relations theory, and indeed theory generally, is ‘irrelevant’ to intelligence studies is simultaneously challenged.
