After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. Despite possessing these nuclear weapons, Ukraine chose to disarm due to financial constraints and geopolitical uncertainties. The 1994 Budapest Memorandum assured security guarantees to Ukraine, but these promises faltered when Russia annexed Crimea and backed separatists in Ukraine. The current Russia-Ukraine conflict underscores the security vulnerabilities faced by Ukraine in the absence of nuclear deterrence. The situation has sparked concerns about Ukraine’s safety and stability in the region. The decision to relinquish nuclear weapons now appears to have left Ukraine exposed to aggression from its neighbors. The international community is closely monitoring the escalating tensions between Russia and Ukraine, with fears of further destabilization in the region. The need for reliable security assurances for Ukraine has become more pressing than ever in light of recent events. It remains to be seen how the global community will respond to the ongoing crisis and what measures will be taken to address the security concerns of Ukraine.
