Transformation of international security mechanisms in the context of the russian-ukrainian war

The article provides a comprehensive analysis of the transformations in international security mechanisms in the context of the Russia-Ukraine war, ongoing since 2014, with a particular focus on the activities of NATO and the United Nations. The author aims to examine the crisis in the effectiveness of traditional security structures, assess their ability to adapt to new geopolitical realities, and identify the need for the creation of new forms of international security. The research methodology is based on the analysis and synthesis of scientific sources, including works dedicated to the activities of international security organizations, as well as the application of a systematic approach to evaluate the effectiveness of existing security mechanisms. The article examines NATO and the UN's decision-making mechanisms and responses to the Russia-Ukraine war, analyzing their capacity to adequately address the new challenges arising from the armed conflict. The author employs comparative analysis methods to study the changes in the activities of these organizations and analyzes expert assessments to identify key changes in their operations. The study concludes that the Russia-Ukraine war has acted as a catalyst for changes in international security mechanisms, revealing the weaknesses and shortcomings of traditional approaches to global stability. This underscores the need to revise existing strategies, seek innovative approaches to ensuring international security, and potentially create new organizations or coalitions capable of responding more effectively to similar conflicts in the future. The findings of this research may be useful for policymakers, international security experts, and all those interested in the transformation of the global security system.
