Korea has been in the news lately after the North launched a supposedly non-military rocket in the direction of Japan. Like most diplomatic kerfluffles, the media have blown this one a bit out of proportion, and Japan made a great showing of getting ready to shoot the thing down. (It's not often the Japan Self-Defense Force gets to play with its toys.)
You're likely to hear some more exaggerated reports over the next couple of days, but don't worry. We're not on the brink of war over here, and life goes on normally.
At least, as normally as it can when you're us.
