After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. However, due to financial burdens and geopolitical risks, Ukraine decided to relinquish its nuclear weapons. The 1994 Budapest Memorandum, which promised security guarantees, was proven unreliable when Russia annexed Crimea and supported separatists in Ukraine. The current Russia-Ukraine conflict underscores the vulnerabilities of Ukrainian security without nuclear deterrence. The decision to give up nuclear weapons has left Ukraine exposed to external threats, making its security situation precarious. The lack of nuclear deterrence has put Ukraine in a difficult position, as it faces ongoing aggression from Russia. The need for a strong security framework has become apparent in light of these events. Ukraine’s reliance on international support and alliances has been tested, and the country continues to seek ways to strengthen its security posture. The repercussions of Ukraine’s nuclear disarmament are being felt as the conflict with Russia persists. It remains to be seen how Ukraine will navigate these challenges and ensure its security in the face of continued threats.
