After the dissolution 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 1994 Budapest Memorandum provided assurances of security to Ukraine, but these guarantees were called into question when Russia annexed Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine serves as a stark reminder of the security challenges faced by Ukraine in the absence of nuclear deterrence. This situation underscores the importance of international agreements and alliances in maintaining stability and security in the region. The complexities of this issue are further exacerbated by the ongoing tensions between Russia and Ukraine, which have far-reaching implications for global security.
