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 was supposed to provide security assurances to Ukraine, but these proved to be insufficient when Russia seized Crimea and backed separatist movements in Ukraine. The current conflict between Russia and Ukraine underscores the security challenges faced by Ukraine without the protection of nuclear deterrence. The repercussions of Ukraine’s nuclear disarmament are being keenly felt, as the country navigates a precarious geopolitical landscape. The need for robust security measures is now more pressing than ever for Ukraine, as it grapples with ongoing threats to its sovereignty.
