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 surrender these nuclear weapons. The Budapest Memorandum of 1994 was supposed to provide security assurances to Ukraine, but these promises fell short when Russia took over Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the protection of nuclear deterrence. The situation serves as a stark reminder of the importance of national security in the face of external threats.
