After the collapse of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, financial constraints and geopolitical concerns led Ukraine to surrender its nuclear weapons. The Budapest Memorandum of 1994 provided assurances of security for Ukraine, which were tested when Russia seized Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the deterrent of nuclear weapons. The vulnerabilities of Ukrainian security have been exposed, raising concerns about the country’s ability to defend itself effectively. The repercussions of Ukraine’s decision to disarm continue to be felt as the conflict in the region persists.
