After the dissolution of the Soviet Union, Ukraine found itself in possession of a considerable 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 nuclear deterrence it once possessed. The vulnerability of Ukrainian security has become a central issue in the ongoing tensions between the two nations. The repercussions of Ukraine’s nuclear disarmament continue to be felt as the country navigates its relationship with Russia and seeks to assert its sovereignty on the international stage.
