The uncomfortable conclusion I've come to recently: the world (and especially the US) has come to terms with a nuclear-armed North Korea being the least bad option in this whole ordeal. Sure, we still need to pass sanctions and throw around words like "unacceptable" a lot for PR purposes. But we've ultimately accepted that there's nothing we can do to stop Kim from getting nukes that doesn't involve laying waste to most of the Korean peninsula, a massive refugee crisis, and the potential that the conflict will already go nuclear.
