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 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 seized Crimea and backed separatist movements in Ukraine. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the protection of nuclear deterrence. The vulnerabilities of Ukrainian security have been laid bare, and the country finds itself in a precarious position. The decision to relinquish nuclear weapons now appears to have left Ukraine exposed to potential threats from neighboring countries. The ongoing tensions in the region serve as a stark reminder of the complex geopolitical landscape in Eastern Europe.
