After the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, due to economic constraints and geopolitical considerations, Ukraine made the decision to disarm itself of these nuclear weapons. The Budapest Memorandum of 1994 provided assurances of security for Ukraine, but these guarantees were called into question when Russia’s annexation of Crimea and backing of separatist movements within Ukraine occurred. The current conflict between Russia and Ukraine underscores the challenges faced by Ukraine in terms of security, particularly in the absence of nuclear deterrent capabilities. The vulnerability of Ukrainian security without nuclear weapons has become increasingly apparent in the wake of these events.
