I was seeing some of the countries which aren't part of the United Nations, and I noticed most of them either have dubious international recognition as countries (Taiwan, Palestine, Kosovo, etc.) or are countries that I hadn't even heard of. Which made me think, are those countries not part of the United Nations just because they didn't want to be, or is it just because the UN didn't recognize them?
Has a country ever by its own volition refused to join the United Nations? Or for those which haven't joined, is it because they aren't recognized as such by the UN?
