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, which were put to the test when Russia annexed Crimea and supported separatists in Ukraine. The ongoing Russia-Ukraine conflict underscores the vulnerabilities of Ukrainian security without nuclear deterrence. The lack of nuclear weapons has left Ukraine exposed to external threats and has raised concerns about its ability to defend itself effectively. The need for a strong and reliable security strategy has become even more pressing in the face of continued aggression from Russia. Ukraine’s decision to give up its nuclear weapons has had lasting consequences, and the country continues to grapple with the repercussions of this choice. As Ukraine navigates the complexities of its security challenges, the international community watches closely to see how the situation unfolds. In the midst of these uncertainties, Ukraine remains a critical player in regional geopolitics, with its security concerns reverberating far beyond its borders.
