Most, especially in Asia, would have missed the above news. If the U.S. were to nuke North Korea, which country will suffer the biggest impact (not talking about South Korea)? China, of course. In an indirect way, the U.S. is warning China to watch its conduct in the South China Sea or keep its reins tight over North Korea. Either way, China out of its own choice or not will have to suffer the fallout of a nuclear strike.
