I don't think China doubts our arsenal. Perhaps they're crapping their pants because the technology they maybe sold/gave to the North doesn't work... China: "Let's just stay calm everybody, ok? There's no need to be hasty here."

If the US and world wipes NK off the map, there's an instant land bridge into China from a US controlled area. Personally, I hope NK is leveled shortly by conventional weapons, and one more wacko state is gone. Maybe the North Koreans will be thankful for their liberation like the Japanese were nice to us after WWII. China probably knows that any invasion into China to take out the communist government would be welcome. They're practically operating a capitalist society anyway. I think if we had control of NK, or had a nice base there, China would be afraid.
