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 made the decision to disarm itself of these nuclear weapons. The Budapest Memorandum of 1994 was supposed to provide security assurances to Ukraine, but these guarantees were called into question when Russia took over Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the challenges that Ukraine faces in terms of security without the presence of nuclear deterrence. The situation serves as a stark reminder of the complex geopolitical landscape in the region and the importance of international agreements in ensuring stability and security.
