I would liken this to my little Jack Russell Terrier. When I wrestle with my Shepard, the little Terrier will always do something to try to gain my attention so that I will play with him instead. His favorite technique is to drop his tennis ball on my foot repeatedly until I make an attempt to pick it up. He then grabs the ball and runs just out of reach and begins teasing me, “See my ball, you really want my ball, come play with me and get the ball!” If I ignore him he will continue to bounce the ball off me to get my attention. He is quite aware that after awhile, I will give him attention.

Some countries are playing the exact same game. They want attention drawn to them. There is a worldwide scramble going on to be recognized as a powerful nation. The method and flavor of the day is: “Envy”. In this case “Nuclear Envy”. This is a classic example of a page right out of the North Korean playbook. “See my toy. You want my toy. Come play with me on my terms!” And obviously it worked:
the new decision by N. Korea's Kim to want a nuclear free pennisula.
