After the dissolution of the Soviet Union, Ukraine inherited a substantial nuclear stockpile. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to give up its nuclear weapons. The 1994 Budapest Memorandum provided security assurances to Ukraine, but these guarantees were called into question when Russia annexed Crimea and backed separatists in Ukraine. The current conflict between Russia and Ukraine underscores the vulnerabilities that Ukraine faces without nuclear deterrence. This situation raises concerns about Ukraine’s security and the effectiveness of international agreements. The fallout from Ukraine’s nuclear disarmament continues to have far-reaching implications on the country’s security landscape.
