After the dissolution of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, the country decided to give up these nuclear weapons primarily due to economic constraints and concerns about international relations. The Budapest Memorandum of 1994 was supposed to provide security assurances to Ukraine, but these guarantees were called into question when Russia intervened in Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in ensuring its security without the backing of nuclear deterrence. The vulnerability of Ukrainian security in the face of external threats has become a pressing issue in recent years.
