After the fall of the Soviet Union, Ukraine found itself in possession of a substantial nuclear stockpile. However, financial constraints and geopolitical concerns led to Ukraine voluntarily giving up its nuclear weapons. The 1994 Budapest Memorandum was supposed to provide security assurances to Ukraine, but these promises fell short when Russia seized Crimea and backed separatists in Ukraine. The current Russia-Ukraine conflict underscores the insecurity faced by Ukraine without the protection of nuclear deterrence. The importance of nuclear weapons in ensuring national security is evident in this ongoing crisis. Ukraine’s decision to disarm now appears to have left the country vulnerable to external threats. The need for a robust security strategy to address these vulnerabilities has become increasingly apparent. The global community is closely watching the developments in this region, as the implications of a nuclear-free Ukraine are being closely analyzed. It remains to be seen how Ukraine will navigate these security challenges in the absence of nuclear weapons.
