Like I said, I'm not too worried about it, even with the new news about the embassies. I don't know of many wars where someone told the other side they were going to attack them, showed them their strike plans, and told them when to expect it.
Kim Jong Un isn't stupid. He knows he doesn't have backing from China, and his time as a dictator would be incredibly short if he went to war with us. Unless you're China, you don't stand a chance against the military of the United States. Even China would have trouble with us.
