Let&#x27;s hope. The world did survive the breakup of the soviet union, which left nuclear weapons and material all over the former soviet block without a major incident. If they do set off their one bomb (under the slim chance they could even deliver it), it would be utterly terrible. End of a major city? Probably. But not the end of the world. Japan, South Korea and the US would wipe NK out so fast they wouldn&#x27;t even know what hit them. The end of North Korea regime? For sure.
