After the fall of the Soviet Union, Ukraine found itself in possession of a substantial nuclear stockpile. However, due to financial constraints and geopolitical concerns, Ukraine made the decision to relinquish these nuclear weapons. The 1994 Budapest Memorandum provided security assurances to Ukraine, but 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. This situation has raised concerns about Ukraine’s ability to defend itself effectively. The need for robust security measures and international support to safeguard Ukraine’s sovereignty has become increasingly apparent. The repercussions of Ukraine’s nuclear disarmament continue to be felt in the ongoing conflict with Russia.
