Questões nucleares no Leste Asiático: a dissuasão nas relações intercoreanas

Abstract

The North Korean government's nuclear development and the external interests of major powers, namely the United States, China, Russia, and Japan, are brought to the center of the analysis, as their interest and impact on security will be greater compared to other nations. It is also essential to understand their dynamics in a potential process of diplomatic reestablishment on the Korean Peninsula. Furthermore, actions taken by the South Korean government regarding North Korea's nuclear development policies and the continuation of a more hostile discourse toward nuclear warhead development policies have also been examined. Through a literature review, a case study will be conducted on North Korea’s nuclearization and diplomatic relations on the Korean Peninsula, using a historical approach and referencing key authors in East Asian international security. Likewise, reports produced by agencies and observatories that monitor relations on the Peninsula, the evolution of nuclear issues, the impact on the security of both North and South Korea, and the diplomatic positioning of global powers are important for validating the arguments in this research. The rise of new actors and elements may alter the landscape established at the beginning of the century by observatories, bringing new directions to relations on the Peninsula and, consequently, among global powers, particularly from 2003 to 2022. With these aspects in mind, the main motivation is to investigate how North Korea's nuclear development affects the perception of South Korea and other influential actors in the power dynamics shaped by the debate on deterrence. Additionally, this study aims to highlight discussions on the establishment of diplomatic relations on the Peninsula, with the support and supervision of major powers.
