After the fall of the Soviet Union, Ukraine found itself in possession of a substantial nuclear stockpile. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to give up its nuclear weapons. The 1994 Budapest Memorandum was supposed to offer security assurances to Ukraine, but these guarantees were called into question when Russia annexed Crimea and provided support to separatist groups within Ukraine. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the protection of nuclear deterrence. This situation has brought to light the vulnerabilities that Ukraine faces in the face of external threats. With ongoing tensions in the region, the issue of Ukraine’s security remains a critical concern.
