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 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 challenges faced by Ukraine in terms of security without the backing of nuclear deterrence. This situation serves as a stark reminder of the importance of reliable security agreements in the face of international threats.
