Based on what I’m seeing, it looks like the Norks are the ones poking the dog. Kim Jong Un is just taking his father’s place at the chess board imo. He wants something and this posturing gets it. perhaps it’s respect from his military leaders. Perhaps he’s just sparring with Obama to see what kind of opponent he is. Perhaps he just wants to intimidate Obama or test the measure of his resolve. Perhaps he wants to go to war and have us turn his palace and his country into rubble with 1,000 lb bombs but I doubt it.
