DISINFO: Zelenskyy is contradicting Ukrainian nationalistic propaganda
A part of Zelensky’s speech on the creation of the UN openly condradicts the official Ukrainian nationalistic propaganda. The Soviet Union was one of the founders of the United Nations. Three Soviet republics – the Russian Soviet Federative Socialist Republic, the Byelorussian Soviet Socialist Republic, the Ukrainian Soviet Socialist Republic – became UN members representing the USSR in the organization. Ukrainian leaders have repeatedly claimed that the modern Ukraine has no historical and ideological links with the Ukrainian Soviet Socialist Republic.
A recurring Kremlin-backed narrative questioning the sovereignty of Ukraine. The Soviet Union plus the Soviet Republics of Belarus and Ukraine were represented in the United Nations since its beginning. This makes Ukraine one the first countries to sign the United Nations Charter: becoming a founding member of the United Nations. When Ukraine's independence was restored in 1991, the Republic of Ukraine inherited Soviet Ukraine's seat in the UN. No Ukrainian leader has questioned sovereign Ukraine's rights and obligations in the UN. Ukraine's official position of the continuity between Soviet Ukraine's seat in the UN and sovereign Ukraine's can be found here
Unlike the claim in the article, the Russian Soviet republic was never a member of the United Nation. The Russian Federation of today is the legal continuator of USSR in United Nations, thus retaining the USSR's position in the security council.
