After the dissolution of the Soviet Union, Ukraine acquired a substantial nuclear arsenal. However, due to economic constraints and geopolitical concerns, Ukraine made the decision to disarm itself of these nuclear weapons. The Budapest Memorandum of 1994 was meant to provide security assurances to Ukraine, but these guarantees were called into question when Russia took over Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the challenges faced by Ukraine in terms of security, especially in the absence of nuclear deterrence. The implications of Ukraine’s denuclearization have become increasingly evident in the face of ongoing tensions with Russia.
