After the fall 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 give up its nuclear weapons. The 1994 Budapest Memorandum was supposed to provide security assurances to Ukraine, but when Russia annexed Crimea and backed separatists in Ukraine, these promises proved to be ineffective. The current conflict between Russia and Ukraine underscores the importance of nuclear deterrence for Ukrainian security. The vulnerabilities of Ukraine without nuclear weapons have been brought to the forefront, making it crucial for the country to reassess its security strategy. The issue of nuclear disarmament in Ukraine continues to be a topic of debate and concern in the region.
