Analyzing the Mutual Geopolitical and Security Complementarity of Iran and Turkey: Border, Energy, and Water

ABSTRACT In recent decades, particularly since 2002, relations between Iran and Turkey have been on the rise and generally expanding. The aim of this paper is to analyse and clarify the reasons for the sustainability of the two countries’ relations while undergoing intermittent eruptions of disputes over the years. In other words, the main question is: why have Iran and Turkey, with their political frictions, routinely embraced rapprochement and collaboration in recent decades? Accordingly, the hypothesis proposed is that a key reason for the ongoing cooperation between Tehran and Ankara in different fields, is the rationale of geopolitical complementarity engendering their security needs in broad meaning, particularly energy security and natural gas. Whilst the logic also applies to water security, both states attach greater importance to border security and energy. In short, their common geopolitical destiny over-rides individual state preferences. To examine this hypothesis, Barry Buzan’s theory based on a broad definition of security as well as regional security complex has been deployed through descriptive analytics.
