After the collapse of the Soviet Union, Ukraine gained possession of a substantial nuclear arsenal. However, the country decided to give up its nuclear weapons due to economic constraints and geopolitical concerns. The Budapest Memorandum of 1994 provided security assurances to Ukraine, but these were called into question when Russia seized 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 a nuclear deterrent. The vulnerability of Ukrainian security has been exposed, emphasizing the importance of reliable security arrangements in the region. The decision to disarm has left Ukraine in a precarious position, relying on international support to safeguard its sovereignty. The repercussions of Ukraine’s nuclear disarmament continue to reverberate amidst ongoing tensions in the region. The geopolitical landscape in Eastern Europe remains complex and volatile, with Ukraine at the center of power struggles between major global players. In this context, the need for robust security mechanisms and diplomatic efforts to ensure stability and peace in the region cannot be overstated.
