NATO's demographic paradox

Russia, cyberterrorism, Da’esh are among the most quoted challenges to NATO mentioned in the organizations’ documents, specialized literature and newspaper articles. How about a subtler, less striking but real challenge like demographic change? Demographic trends are increasingly recognized as relevant in understanding international politics and particularly international security, but only seldom taken into consideration when dealing with NATO’s future challenges. NATO, hence, suffers from the limits of a political–military institution designed for a post-Second World War demographic and security context that is changing drastically–and is expected to change even more in the foreseeable future. The aim of this article is to explore the current and projected demographic trends at the global level, evaluate their security implications and then draw inferences for the challenges and opportunities that will arise for NATO out of the sketched scenarios. Based on this analysis, we posit that the Alliance is facing a demographic paradox, whereby it is increasingly unable to cope with external demographic challenges because internal demographic changes are weakening the cohesion needed to provide an effective response.
