After the collapse of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to give up its nuclear weapons. The 1994 Budapest Memorandum was supposed to provide security assurances to Ukraine, but these guarantees were called into question when Russia annexed Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the precarious nature of Ukrainian security in the absence of nuclear deterrence. This situation has raised concerns about Ukraine’s ability to defend itself against external threats. The history of Ukraine’s nuclear disarmament and the subsequent events have put a spotlight on the country’s vulnerability and the challenges it faces in ensuring its national security. The need for reliable security arrangements and support from the international community has become increasingly apparent in light of these developments. The ongoing tensions between Russia and Ukraine serve as a stark reminder of the complex geopolitical dynamics at play in the region. As Ukraine navigates these challenges, the importance of finding sustainable solutions to safeguard its sovereignty and territorial integrity has become more pressing than ever.
