After the collapse of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to surrender its nuclear weapons. The Budapest Memorandum of 1994 was supposed to provide 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 nuclear deterrence. The delicate situation in Ukraine serves as a reminder of the complexities of international relations and the importance of strategic decision-making. The aftermath of Ukraine’s nuclear disarmament continues to have far-reaching implications for the country and its relationship with neighboring nations. The need for effective security measures and diplomatic solutions is more pressing than ever in the context of the ongoing tensions in Eastern Europe.
