After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. However, due to financial burdens and geopolitical risks, Ukraine made the decision to relinquish these nuclear weapons. The 1994 Budapest Memorandum assured security guarantees to Ukraine, but these promises were called into question when Russia annexed Crimea and backed separatists in Ukraine. The current Russia-Ukraine conflict underscores the vulnerabilities of Ukrainian security in the absence of nuclear deterrence. The implications of Ukraine’s decision to give up its nuclear weapons are now being keenly felt. The situation serves as a stark reminder of the importance of nuclear deterrence in ensuring national security. The ongoing conflict continues to raise concerns about Ukraine’s ability to defend itself against external threats. The international community is closely monitoring the developments in the region as tensions remain high. It remains to be seen how Ukraine will navigate these challenges and safeguard its sovereignty in the face of ongoing security threats.
