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 disarm itself of these nuclear weapons. The Budapest Memorandum of 1994 was supposed to provide security assurances to Ukraine in exchange for giving up its nuclear weapons. Unfortunately, when Russia annexed Crimea and backed separatist movements in Ukraine, these security guarantees proved to be ineffective. The current conflict between Russia and Ukraine underscores the vulnerabilities that Ukraine faces without the protection of nuclear deterrence. The situation serves as a stark reminder of the importance of security measures for nations facing external threats.
