China has jumped in.
Says if NK strikes US first, it will let US retaliate.
Says if US strikes first, it will defend NK.
So, NK gets to keep its nukes and keep on taunting US.
Trump has overplayed his hand.  His only option in light of China's stance, is to continue to try and provoke NK into a first strike.  And, in light of the technology available to let Chinese "watch" what actually happens, Trump can't "fake" (wag the dog) an NK first strike.
This is the position NK wanted.  It can make all the noise it wants.  It can "test" all it wants.  It can taunt Trump all it wants.  So long as it doesn't first strike (which it doesn't want to do anyway, because war with the US WILL lead to obliteration).
China is now publicly recognizing that the US MIGHT initiate, by publicly addressing (and warning) what it would do IF the US did so (which would be to defend NK).  Why?  Because Trump's big body act has given China (as well as NK) every reason to believe Trump would do so.
