After the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear stockpile. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to surrender these nuclear weapons. The Budapest Memorandum of 1994 offered security assurances to Ukraine, but these guarantees were called into question when Russia annexed Crimea and provided support to separatist movements within Ukraine.

The vulnerabilities of Ukrainian security have been brought to the forefront, emphasizing the complexities of the region’s geopolitical landscape. The repercussions of Ukraine’s nuclear disarmament continue to reverberate, shaping the dynamics of international relations in Eastern Europe.
