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 risks. The 1994 Budapest Memorandum assured security guarantees to Ukraine; however, these guarantees were called into question when Russia annexed Crimea and backed separatists in Ukraine. The current Russia-Ukraine conflict underscores the security vulnerabilities faced by Ukraine in the absence of nuclear deterrence. The decision to denuclearize has left Ukraine exposed to potential threats, as evidenced by the ongoing tensions in the region. The situation serves as a cautionary tale for countries considering disarmament in a volatile geopolitical landscape.
