Following the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, financial constraints and geopolitical concerns led to Ukraine deciding to give up its nuclear weapons. The Budapest Memorandum of 1994 provided security assurances to Ukraine, but they were called into question when Russia seized Crimea and backed separatist movements in Ukraine. The current ongoing conflict between Russia and Ukraine underscores the challenges that Ukraine faces in terms of security without the protection of nuclear deterrence. The vulnerability of Ukrainian security has been brought to the forefront, emphasizing the need for reliable security measures in the region.
