After the fall of the Soviet Union, Ukraine inherited a significant nuclear stockpile. Despite possessing these nuclear weapons, Ukraine chose to give them up due to financial constraints and geopolitical concerns. The 1994 Budapest Memorandum offered security assurances, but these proved futile when Russia seized Crimea and backed separatists in Ukraine. The current Russia-Ukraine conflict underscores the weaknesses in Ukrainian security without a nuclear deterrent. This situation has raised questions about Ukraine’s security and the effectiveness of international agreements in safeguarding its sovereignty. The repercussions of Ukraine’s nuclear disarmament continue to be felt as the country grapples with ongoing threats to its territorial integrity. The need for robust security measures and support from the international community remains crucial for Ukraine’s stability and sovereignty in the face of external aggression.
