After the collapse of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal. However, financial constraints and geopolitical concerns led Ukraine to surrender its nuclear weapons. The 1994 Budapest Memorandum offered security assurances to Ukraine, but these proved to be ineffective when Russia seized Crimea and backed separatists in Ukraine. The current Russia-Ukraine conflict underscores the security challenges faced by Ukraine in the absence of nuclear deterrence. The vulnerability of Ukrainian security has become a pressing issue in the wake of these developments.
