One hit on the US and I think it's safe to say they would find themselves missing from the earth. I believe the US has nukes powerful enough to obliterate North Korea. The problem is that China is on good terms with them. When it came down to it though, I wonder if China would side with North Korea if NK started junk with the US. I don't think China OR the US wants to get into a war with eachother. They try to keep on good terms as well at least making sure to give fake smiles for the cameras and photo ops. Deep down though I don't think either would want to fight eachother, and I think negotiations would be a much more viable solution if it came down to it.
One nuke wouldn't be able to take out North Korea by itself. It would probably take two or three. But there are enough nukes out there to destroy the world a couple of times over
