After the disintegration of the Soviet Union, Ukraine found itself in possession of a considerable nuclear arsenal. However, due to financial constraints and geopolitical considerations, Ukraine made the decision to give up its nuclear weapons. This move was further reinforced by the 1994 Budapest Memorandum, which provided security assurances to Ukraine. Unfortunately, these commitments were called into question when Russia annexed Crimea and backed separatist movements in Ukraine. The current conflict between Russia and Ukraine serves as a stark reminder of the vulnerabilities faced by Ukraine without the backing of nuclear deterrence. The situation underscores the complex interplay of politics and security in the region. The need for reliable security guarantees has become even more pressing for Ukraine in the face of ongoing tensions.
