> Right. Because nothing says "I can mind my own business." like nuclear weapons being at most one coup from being launched at someone, possibly you.

You're saying not all countries should be able to have powerful weapons just because there might be a coup. Who decides that? You? Me? A random guy on the street? A random bureaucrat from a random country?

There are very few people who think they can win a nuclear exchange. And somehow I don't think a random guy in Africa or the Middle East is so sure about it that it risks launching nukes at its neighbor(s).
