After the dissolution 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 give up its nuclear weapons. The Budapest Memorandum of 1994 offered security assurances to Ukraine, but these proved to be inadequate when Russia seized Crimea and backed separatist movements within Ukraine. The ongoing 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 complexities and challenges that Ukraine encounters in the realm of national security.
