Because both North and South Korea have inexperienced leaders, this situation may get out of control. I have a different take on this. Something really bad must be happening in N. Korea.Over the years I've paid any attention to N. Korea, whenever something really bad happens internally (crop failure, etc.), they make outrageous threats. The U.S., S. Korea and others sit down w/ them and talk. When N. Korea gets what they need, such as a deal on wheat, magically the bluster goes away.
