Basically, the NK has one shot at launching a missile at us. The purpose of their nuclear program is to keep us from performing a regime-change, ala Iraq or even Syria with their nuclear program. Once they launch the missile, the peninsula will be bombed to the stone age (it's already almost there). The question is how accurate is their missile assuming they can develop a workable reentry vehicle that won't burn up the nuke. Hawaii is a small target in a big ocean. The last missile got close to Japan. If they accidentally hit Japan, then we can accidentally shoot one of our missiles at them, and the escalation starts. I'm more fearful for Japan than I am about us. Eventually, the NK will get to the point where they will need to test their long range missile, and shit will start getting real then.
