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.
When I was a kid (in the 50s) we’d sometimes get sets of flags of UN nations. They included the flags of Ukraine and Byelorussia—as I recall, they looked like the USSR flag with some kind of design on the bottom or side. When I asked why “Russia” got three votes and we only got one, the teacher’s reply was something like “because it is so big”. In high school I was told that Stalin insisted on extra votes as a price for the USSR’s joining the UN—he felt that his side would lose every vote. Remember, this happened before most of the ‘third world’ were independent and had seats in the UN.
