After the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, financial constraints and geopolitical concerns prompted Ukraine to give up its nuclear weapons. The 1994 Budapest Memorandum was meant to provide security assurances to Ukraine, but these guarantees were called into question when Russia annexed Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the vulnerabilities that Ukraine faces without the protection of nuclear deterrence. The relinquishment of nuclear weapons has left Ukraine exposed to external threats, as evidenced by the ongoing tensions in the region. The situation serves as a stark reminder of the complex geopolitical landscape in Eastern Europe and the challenges faced by countries like Ukraine in ensuring their security. The need for reliable security mechanisms is more pressing than ever as Ukraine navigates the complexities of international relations in the region.
