After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. Despite possessing these nuclear weapons, Ukraine decided to relinquish them due to financial burdens and geopolitical risks. The 1994 Budapest Memorandum promised security guarantees to Ukraine, which unfortunately proved unreliable when Russia annexed Crimea and supported separatists in Ukraine. The current Russia-Ukraine conflict sheds light on the vulnerabilities of Ukrainian security without nuclear deterrence. The decision to give up nuclear weapons has left Ukraine in a precarious position, facing aggression from its powerful neighbor. The lack of a nuclear deterrent has made Ukraine more susceptible to external threats and has raised concerns about its ability to defend itself effectively. The international community is closely monitoring the situation, as the conflict continues to escalate, and tensions remain high in the region. It remains to be seen how Ukraine will address its security challenges in the absence of nuclear weapons and whether it will seek alternative means to ensure its sovereignty and territorial integrity.
