After the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, due to financial constraints and geopolitical considerations, Ukraine made the decision to surrender its nuclear weapons. The 1994 Budapest Memorandum provided assurances of security to Ukraine, but these guarantees were called into question when Russia took over Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the vulnerabilities that Ukraine faces in terms of security without the protection of nuclear deterrence. This situation serves as a stark reminder of the importance of strategic defense measures in the face of external threats.
