After the collapse of the Soviet Union, Ukraine found itself in possession of a considerable nuclear arsenal. However, due to financial constraints and concerns about geopolitical stability, Ukraine made the decision to disarm itself of these nuclear weapons. The Budapest Memorandum of 1994 provided assurances of security to Ukraine, but recent events, such as Russia’s annexation of Crimea and its support for separatists in Ukraine, have shown that these guarantees may not be as reliable as initially thought. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the backing of nuclear deterrence. The vulnerability of Ukrainian security has been brought to the forefront, raising concerns about the country’s ability to defend itself effectively.
