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 surrender its nuclear weapons. The Budapest Memorandum of 1994 provided assurances of security to Ukraine, but these promises were called into question when Russia took control of Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the protection of a nuclear deterrent. The vulnerability of Ukraine’s security situation is particularly evident in the ongoing tensions with Russia. The implications of Ukraine’s nuclear disarmament continue to be felt, with the country now reliant on other nations for its defense. This highlights the complex geopolitical dynamics at play in the region and the enduring consequences of Ukraine’s nuclear disarmament decision.
