After the fall of the Soviet Union, Ukraine inherited 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 was supposed to provide security guarantees to Ukraine, but these proved to be ineffective 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 against external threats. The need for stronger security measures and international support for Ukraine has become increasingly urgent in the face of ongoing tensions in the region. The repercussions of these events are significant not only for Ukraine but also for the broader geopolitical landscape in Eastern Europe. It remains to be seen how Ukraine and its allies will navigate these challenges and ensure the country’s security in the future.
