After the collapse 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 give up its nuclear weapons. The 1994 Budapest Memorandum offered security assurances to Ukraine, but these guarantees proved to be ineffective when Russia seized Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the vulnerabilities that Ukraine faces in terms of security without the backing of nuclear deterrence. The situation serves as a stark reminder of the challenges that Ukraine continues to grapple with in the realm of national security.
