After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. However, due to financial burdens and geopolitical risks, Ukraine relinquished these nuclear weapons. The 1994 Budapest Memorandum promised security guarantees to Ukraine, but these guarantees proved unreliable when Russia annexed Crimea and supported separatists in Ukraine. The ongoing Russia-Ukraine conflict underscores the vulnerabilities of Ukrainian security without nuclear deterrence. The decision to give up nuclear weapons has left Ukraine exposed to external threats and has raised concerns about its ability to defend itself. The lack of a nuclear deterrent has made Ukraine dependent on international support, which has not always been forthcoming. As tensions continue to escalate between Russia and Ukraine, the issue of nuclear disarmament and its impact on security remains a key concern for the region. The events unfolding in Ukraine serve as a stark reminder of the complex geopolitical challenges facing the country and the importance of strategic decision-making in matters of national security.
