Spine of Jellyfish?

So, North Korea has tested a nuclear weapon, despite our warnings. It is now time to see if our threats have some backbone to them. Kim has continuously defied the world and has been rebuffed each time. Does he give a darn? No, because all we do is threaten sanctions over and over and threaten with talks. Despots do not respond to talks they respond to violence. We need to either sabotage their country and cause as peaceful a revolution as possible, or we need to attack. Although I hate war, we went into war in Iraq because they supposedly had nukes. Kim not only has nukes, but he is a nut and will probably sell nukes to his good friends in Iran. The world needs to stop being so pusillanimous.
