After the fall of the Soviet Union, Ukraine found itself in possession of a substantial nuclear stockpile. However, due to financial constraints and geopolitical uncertainties, Ukraine made the decision to disarm itself of these 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 serves as a stark reminder of Ukraine’s vulnerability without the nuclear deterrence it once possessed. The security landscape in Ukraine has been significantly altered, and the country now faces increased risks and challenges. The repercussions of Ukraine’s decision to disarm continue to be felt as the nation navigates its security concerns in the face of ongoing tensions with Russia.
