After the disintegration of the Soviet Union, Ukraine found itself in possession of a considerable nuclear arsenal. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to give up its nuclear weapons. The Budapest Memorandum of 1994 was supposed to provide security assurances to Ukraine, but these guarantees were called into question when Russia annexed Crimea and backed separatist movements in Ukraine. The current conflict between Russia and Ukraine underscores the security challenges faced by Ukraine in the absence of nuclear deterrence. This situation raises concerns about Ukraine’s vulnerability and the need for reliable security measures. The ongoing tensions in the region have drawn attention to the complex geopolitical dynamics at play and the implications for global security.
