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. The Budapest Memorandum of 1994 was supposed to provide security assurances to Ukraine, but these proved ineffective when Russia intervened in Crimea and backed separatist movements within Ukraine. The current conflict between Russia and Ukraine underscores the security challenges faced by Ukraine in the absence of a nuclear deterrent. The issue of nuclear disarmament in Ukraine continues to be a topic of debate and concern in international relations.
