Worry about this is only human. We all are concerned with the safety of all. The North Koreans are so brain washed that they think that the USA is actually a threat to them and they need to bomb us first. Any outside information that they get is monitored as to what they can hear. And they support their leader, or will have harmful consequences if they don't. Their leader is just crazy enough to start something though. Nuclear detonation will have ramifications around the world where ever it lands or explodes.
I think they should have addressed him much earlier, but so many thought he would never reach the level that he has. That was a stupid oversight.
Let's just hope someone call talk some sense in him and he stands down. They will have to deal with him eventually. He's not going to stop being a threat to the USA or USA controlled territories. Everyone is entitled to their own opinion and how they may prepared for an act of war against the USA. I for one am making plans for survival, but that's just me.
