North Korea's saber rattling again shook the world Wednesday. Pyongyang vowed to shut down a key military hotline with South Korea. It was another day of hostile, over-the-top rhetoric from the reclusive, impoverished nation led by Kim Jong Un. But the recent missile and nuclear tests, and the annulment of the 1953 Korean War armistice are raising questions about the young leader. Is his behavior erratic or staged? Is he competent enough to run a government? Pyongyang watchers, reading the news and the tea leaves, say the latest hot air wafting over the Korean Peninsula could reflect an effort to prop up appeal and allegiance for Kim.
