After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. Despite possessing these nuclear weapons, Ukraine decided to give them up due to financial constraints and geopolitical concerns. The 1994 Budapest Memorandum provided security assurances to Ukraine, but these guarantees were called into question when Russia seized Crimea and backed separatists in Ukraine. The current conflict between Russia and Ukraine underscores the security challenges faced by Ukraine without the protection of nuclear deterrence. The vulnerability of Ukrainian security has been exposed in the ongoing tensions with Russia. The decision to disarm has left Ukraine in a precarious position, relying on international support to defend its sovereignty. The need for robust security measures and alliances is now more critical than ever for Ukraine. The country’s historical nuclear disarmament has significantly impacted its current security landscape, with the threat of Russian aggression looming large. It remains to be seen how Ukraine will navigate these challenges and ensure its security in the face of ongoing geopolitical tensions.
