After the collapse of the Soviet Union, Ukraine took possession of a large nuclear arsenal. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to surrender its nuclear weapons. The Budapest Memorandum of 1994 provided assurances of security, but these guarantees were called into question when Russia seized Crimea and backed separatist movements in Ukraine. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the protection of nuclear weapons. The vulnerability of Ukrainian security has become a prominent issue in light of these events.
