Introduction. This article examines the impact of the U.S. military presence in Northeast Asia on world security through a geopolitical approach. In the introducetion the author substantiates the relevance of the work, which is due to the growing strategic importance of Northeast Asia for the modern world political system and the escalation of military and political tensions between the U.S. and China and U.S. and Russia.

Materials and methods. According to the author, the essence of the geopolitical approach is the convergence of A. Mahan’s concept of sea power and G. Douhet’s concept of air power.

Results of the study. The limitations of the geopolitical approach are shown, as it does not fully take into account the factor of subjective perception and global problems.

Discussion. In the main part the author examines the current state of the American military presence in Northeast Asia and its possible impact on global security within the framework of the geopolitical approach. The results of the main part suggest that the U.S. retains military superiority in Northeast Asia. However, the geopolitical approach does not provide an objective analysis of the balance of power and threats in the region in sea and air space.

Conclusions. The author concludes that the geopolitical approach is a necessary, but not the only important element in the theoretical framework for studying the impact of the military presence in Northeast Asia. Its convergence with other concepts seems important. At the same time, within the framework of the geopolitical approach one can argue about the ambiguous influence of the U.S. military presence in Northeast Asia on global security.
