Japan–South Korea Security Cooperation: Sisyphus Getting Muscles?

Abstract

This article aims to assess the progress of the ROK-Japan security cooperation in recent years, both in the bilateral and trilateral framework involving the United States. It argues that the unprecedented progress in North Korea’s nuclear program, along with a constant U.S. persuasion, led to a certain political convergence to allow and accompany the security cooperation. This said, political mistrust, asymmetric expectations and diverging perspectives still persist, explaining why the cooperation is mainly taking place within the trilateral framework. Nevertheless, the latest set of dialogue, exchanges and joint exercises did build up confidence and highlighted the benefit of an expanded cooperation while pushing the two countries to seriously consider the concrete issues, conditions and implications of such cooperation. The paper concludes that the recent progress in the security cooperation is still fragile and dependent on external factors, even if it is pointing to a greater understanding.
