The role and importance of the collective security treaty organization in the security system of the post-soviet area

The collapse of the USSR resulted in the decomposition of the security system in the post-Soviet Region. The states established after the collapse of the USSR were looking for new security guarantees, fearing for the future, especially at the beginning of shaping their statehood. However, the Russian Federation sought to reintegrate the post-Soviet area for historical and political reasons. Its goal was to subjugate the post-Soviet states and maintain its sphere of influence in the region. It created the Collective Security Treaty Organization, which was to be an institutional form of integration of the countries of the post-Soviet area under the leadership of Russia. Its actions were also aimed at eliminating the influence of European countries and the PRC in this region. The main aim of the article is to analyze the military and political activities of the Collective Security Treaty Organization and the importance of the Russian Federation in it. The article presents the main decision-making bodies of the organization, political processes and actions undertaken by the CSTO. It also pays attention to a significant challenge for the CSTO created by the armed intervention of the Russian Federation in Ukraine in 2022.
