After the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to surrender its nuclear weapons. The 1994 Budapest Memorandum was supposed to provide security assurances to Ukraine, but these promises were shattered when Russia annexed Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the importance of nuclear deterrence for Ukraine’s security. The vulnerabilities of Ukraine’s security apparatus have been laid bare in the face of Russian aggression. Ukraine’s decision to relinquish its nuclear weapons now appears to have left it exposed and at the mercy of its more powerful neighbor. The ongoing tensions between Russia and Ukraine serve as a cautionary tale for other nations considering giving up their nuclear capabilities in exchange for promises of security. It is a stark reminder of the complex geopolitical landscape and the harsh realities of international relations.
