After the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear stockpile. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to surrender these nuclear weapons. The 1994 Budapest Memorandum was supposed 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 in terms of security without the presence of nuclear deterrence. The issue of nuclear disarmament and its impact on Ukrainian security has once again come to the forefront in light of these recent events.
