After the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear stockpile. However, financial constraints and geopolitical concerns led to Ukraine voluntarily surrendering its nuclear weapons. The 1994 Budapest Memorandum provided security assurances to Ukraine, but these guarantees were called into question when Russia annexed Crimea and backed separatists in Ukraine. The current conflict between Russia and Ukraine underscores the security challenges that Ukraine faces without the protection of nuclear deterrence. This situation serves as a reminder of the delicate balance of power in the region and the importance of international agreements in ensuring stability. The vulnerability of Ukrainian security in the face of aggression is a pressing issue that continues to be a cause for concern.
