After the dissolution 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 surrender these nuclear weapons. The Budapest Memorandum of 1994 provided assurances of security, 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 security challenges faced by Ukraine in the absence of nuclear deterrence. This situation raises important questions about Ukraine’s national security and its ability to defend itself against external threats. The geopolitical landscape in Eastern Europe has been significantly impacted by these developments, with implications for regional stability and international relations. The ongoing tensions between Russia and Ukraine serve as a reminder of the complex dynamics at play in this volatile region. It remains to be seen how Ukraine will navigate these challenges and ensure its security in the face of ongoing threats.
