Abstract

The Collective Security Treaty Organization (CSTO) has long been a central player in maintaining security and stability in Central Eurasia, particularly among former Soviet republics. However, the ongoing Russo-Ukrainian conflict has tested the organization’s relevance and effectiveness in the current geopolitical climate. This paper seeks to examine the future of the CSTO in the post-Ukraine war context, focusing on its capacity to address regional security challenges and maintain influence in an era of shifting alliances. With Russia’s increasing isolation from the West and its strained relationships with neighboring countries, the CSTO’s role has come under scrutiny. By analyzing recent developments within the organization and the geopolitical realignments occurring within Central Eurasia, this paper explores whether the CSTO can remain a cohesive security structure or if regional powers will seek alternative security arrangements. Furthermore, the paper discusses the potential impact of Russia’s weakened influence on CSTO member states and how these nations may navigate new security dynamics.
