My dad had some interesting insights into this as a retired Methodist pastor. Fun fact. In order to get this result, there was a suspicious delay of inviting the African delegations so they couldn't attend in time. Historically, they've always voted conservatively. How racist can you get? As I say, thank God for North Katanga....

They also cut off the option to secede once they got the vote. The one that was graciously put in place for THEM in case the vote didn't go their way. Vipers and scorpions, the lot of them.
