An American diplomat got in trouble for saying something, well, undiplomatic.

Victoria Nuland, a top State Department official, thought she was having a private phone conversation. She was speaking about developments in Ukraine with the U.S. ambassador to that country, Geoffrey Pyatt. And she was speaking bluntly, even using a not-so-choice word about America's European allies.

Almost every day, there's some new threat out of North Korea.

It's hard to determine how seriously to take these threats. War on the Korean Peninsula could be catastrophic, so the bluster can't be dismissed. On the other hand, North Korea has a long history of hyperbole, of making threats it doesn't follow through on.
