What is North Korea Thinking?!

I have no idea what North Korea is thinking.  I guess they don’t think they can play in the rest of the world and no one matters, especially their own people.  The rest of the world has ceased these type of tests.  Here are a couple of links to stories.  One from the BBC and they other from CNN.
I am sure that there will be more coming in the morning, but you would think that one of the worlds poorest countries would be more concerned about feeding its people than spending money on nuclear bombs.  But, North Korea has shown that its crazy leader worries more about inflating his own ego than helping its people.  And he might just start a war over it.
