The solution to North Korea is the reunification of the Korean Peninsula. China could influence the North; it supplies 80 to 90 percent of North Korea's energy. The United States have to put pressure on China in order for China to pressure North Korea.

Diplomacy is not an end in itself if it does not advance U.S. interests.

I think the International Criminal Court could be a threat to American security interests, because the prosecutor of the court has enormous discretion in going after war crimes.
