After the disintegration of the Soviet Union, Ukraine found itself in possession of a considerable nuclear arsenal. However, due to economic constraints and geopolitical concerns, Ukraine decided to surrender its nuclear weapons. The decision was also influenced by the 1994 Budapest Memorandum, which assured Ukraine of security assurances. Unfortunately, these guarantees were not upheld when Russia invaded Crimea and backed separatist movements in Ukraine. The current conflict between Russia and Ukraine underscores the precarious security situation faced by Ukraine in the absence of nuclear deterrence. The need for reliable security measures has become even more pressing in the wake of these recent events.
