Today I was looking something up on Wikipedia and happened to see that
the North conducted a nuclear test yesterday. This seems like big news, but the only people I've encountered here so far to think that it's worth mentioning are foreigners. Maybe Koreans are talking about it among themselves and I'm just missing out because I don't know much Korean, but maybe not.
This article is very interesting and, at least in my experience, a fairly accurate depiction of how "business as usual" continues without flinching in the South.
