After the dissolution of the Soviet Union, Ukraine acquired a substantial nuclear arsenal. However, due to economic constraints and geopolitical challenges, Ukraine chose to surrender its nuclear weapons. The Budapest Memorandum of 1994 provided security assurances to Ukraine, yet these proved insufficient when Russia seized Crimea and backed separatists in Ukraine. The current conflict between Russia and Ukraine underscores the importance of nuclear deterrence for Ukrainian security. The decision to disarm has left Ukraine vulnerable to external threats, raising concerns about its national security. The unresolved conflict continues to pose challenges for Ukraine, emphasizing the need for reliable security measures in the region.
