The two countries should be extra carefully because two of them posses nuclear weapon I don't think they will confront each other they are just playing politics
I do not think that there will be no war because North Korea have nothing to resist US. I think Americans need to carry out pre-emptive strike on Korea until they have good missiles. Moreover, I think that those missiles that Kim is not all can fly. North Korea is a backward country, and the same with their weapons.
