After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. Despite possessing these nuclear weapons, Ukraine decided to give them up due to financial constraints and geopolitical risks. The 1994 Budapest Memorandum had assured security guarantees to Ukraine; however, these guarantees proved futile when Russia annexed Crimea and backed separatists in Ukraine. The current Russia-Ukraine conflict underscores the security vulnerabilities faced by Ukraine without the nuclear deterrence that it once had. The decision to relinquish nuclear weapons has left Ukraine exposed to external threats and has raised questions about the efficacy of international security agreements. This situation has reignited debates about the necessity of nuclear weapons for ensuring national security. The ongoing conflict serves as a stark reminder of the complex geopolitical dynamics at play in Eastern Europe and the enduring tensions between Ukraine and Russia. The repercussions of Ukraine’s disarmament decision continue to reverberate, with implications not only for the country itself but also for regional and global security. The need for a robust security apparatus and reliable international alliances has become increasingly apparent in light of the ongoing crisis. It remains to be seen how Ukraine will navigate these challenges and ensure its sovereignty and territorial integrity in the face of ongoing threats.
