North Korea Tests a Nuke - Again

Do the North Korean nuclear tests imply that the united Korea of the future will be a nuclear weapons state?

But if Mr. Xi took the measures against North Korea that the United States wants, Chinese and American analysts say, Mr. Xi would risk destabilizing North Korea, spurring its collapse and pushing the creation of a unified Korean Peninsula that could well turn out to be an American ally. An American-controlled Korean Peninsula is not an option for Mr. Xi, the analysts agree.
