The Ukranian SSR and the Byelorussian (sp) SSR as well as the USSR each had a vote in the General Assembly. Stalin insisted on getting three votes at the UN. He may have wanted all the “republics” to get one and got bargained down to only three, but he did get extra votes.
I thought the Ukraine had something akin to an “amicus” vote, but not a recognized independent vote. I’ll have to go back to my history books to check on that.
