After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. However, due to financial burdens and geopolitical risks, Ukraine made the decision to relinquish these nuclear weapons. The 1994 Budapest Memorandum was supposed to provide security guarantees to Ukraine, but these proved to be unreliable when Russia annexed Crimea and supported separatists in Ukraine. The current Russia-Ukraine conflict serves as a stark reminder of the vulnerabilities of Ukrainian security without nuclear deterrence. The issue of Ukraine’s nuclear disarmament and its implications on current geopolitical tensions continue to be a topic of great interest and concern.
