After the collapse of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, facing financial constraints and geopolitical challenges, Ukraine made the decision to give up its nuclear weapons. The Budapest Memorandum of 1994 provided assurances of security to Ukraine, but these guarantees were called into question when Russia took control of Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the vulnerabilities Ukraine faces in terms of security without the protection of nuclear deterrence. The implications of Ukraine’s disarmament have become increasingly apparent as tensions in the region continue to escalate. The need for reliable security measures has become more pressing than ever for Ukraine in the face of ongoing threats from Russia.
