After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. However, due to financial burdens and geopolitical risks, Ukraine relinquished its nuclear weapons. The 1994 Budapest Memorandum promised security guarantees to Ukraine, but these proved unreliable when Russia annexed Crimea and supported separatists in Ukraine. The ongoing Russia-Ukraine conflict underscores the vulnerabilities of Ukrainian security without nuclear deterrence. The decision to give up nuclear weapons has left Ukraine exposed and reliant on international support for its defense. This situation has significant implications for global security and the balance of power in the region. The unresolved conflict between Russia and Ukraine continues to escalate tensions and raise concerns about the stability of Eastern Europe. The need for a robust security strategy and support from allies is crucial for Ukraine to navigate these challenging circumstances. The international community must remain vigilant and actively engage in diplomatic efforts to address the ongoing crisis and prevent further escalation of hostilities.
