After the dissolution of the Soviet Union, Ukraine became the custodian of a considerable nuclear arsenal. However, due to economic challenges and geopolitical concerns, Ukraine made the decision to disarm itself of these weapons. The Budapest Memorandum of 1994 was supposed to provide security assurances to Ukraine, but these proved to be insufficient when Russia seized Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the security vulnerabilities that Ukraine faces without the protection of nuclear deterrence. This situation has raised concerns about Ukraine’s ability to defend itself effectively. The need for stronger international support and security measures for Ukraine has become increasingly apparent in the face of ongoing tensions in the region.
