After the disintegration of the Soviet Union, Ukraine found itself in possession of a considerable nuclear arsenal. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to give up its nuclear weapons. The Budapest Memorandum of 1994 provided assurances of security to Ukraine, but these promises were not upheld when Russia took over Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the nuclear deterrence it once had. The vulnerability of Ukrainian security has been brought to the forefront in light of these developments, emphasizing the importance of international alliances and support for Ukraine’s sovereignty.
