After the fall of the Soviet Union, Ukraine found itself in possession of a substantial nuclear stockpile. However, financial constraints and geopolitical uncertainties led Ukraine to surrender its nuclear weapons. The 1994 Budapest Memorandum offered security assurances to Ukraine, but these guarantees were called into question when Russia annexed Crimea and backed separatists in Ukraine. The current conflict between Russia and Ukraine underscores the security challenges faced by Ukraine in the absence of nuclear deterrence. The need for reliable security measures has become increasingly apparent in light of these developments.
