The dangers involved are now on clear display in the escalating crisis in North Korea as the United States seeks to strike a delicate balance between deterring an unknown adversary and reassuring a nervous ally.

However, like many Koreans, most of the expat community shrugs it off, likening the threats to whining from a petulant child.
