The transition from a bipolar to a multipolar world order following the Cold War has profoundly affected international security. This article examines the implications from the dissolution of the Union of Soviet Socialist Republics (USSR), focusing on NATO's enlargement and nuclear proliferation. Such developments have strained post-Cold War relations and increased global security concerns. The hypothesis suggests that the end of the USSR has significantly impacted international stability. It asserts that NATO's expansion in the Liberal International Order (LIO) has contributed to tensions with the Russian Federation, leading to an adversarial relationship. Nuclear proliferation, exploiting the dissolved bipolar structure, has complicated arms control negotiations and intensified the risk of nuclear conflict. This research paper highlights the West’s failure to recognize Russia's security interests and hegemonic pursuits. Using the framework of the LIO, it examines the principles of cooperation, democracy, and multilateralism, offering a lens to address the complex challenges and work toward a future characterized by security and collaboration. By shedding light on the interplay between nuclear proliferation, NATO's enlargement, and the LIO, it underscores the importance of addressing the security concerns of all nations and fostering a cooperative and reliable future.
