After the disintegration of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, due to economic constraints and geopolitical concerns, Ukraine made the decision to surrender its nuclear weapons. The Budapest Memorandum of 1994 was supposed to provide security assurances to Ukraine, but the annexation of Crimea by Russia and its support for separatist movements in Ukraine have shown the limitations of such agreements. The current conflict between Russia and Ukraine underscores the security challenges faced by Ukraine in the absence of nuclear deterrence. The vulnerability of Ukrainian security has been laid bare, raising concerns about the country’s ability to defend itself effectively. The ongoing tensions in the region have reignited debates about the role of nuclear weapons in ensuring national security.
