Not necessarily China & Russia.  They would only become involved if they chose to defend the racist, fascist dictator, Kim, who has threatened to murder millions of innocent, defenseless people around the globe.

Your position is that the US and its allies should wait for Kim to start a nuclear holocaust before responding.

Kim is a maniac with thermonuclear as well as biological and chemical weapons.

Yet you wish to allow him to continue his WMD proliferation until he can wipe out vast swaths of humanity.

Very sad.
