God is great! This is excellent news, and a severe blow for the American warmongers. Moon Jae-in is opposed to provoking the DPRK and its leader Kim Jong Un. He is likely to pursue a conciliatory approach with the northern neighbor.
And I think he makes a mistake. Trump will not tolerate the fact that Kim is trying to develop missiles of distant radius of action. In any case he will hit Kim. The only difference is that if the Americans removed their missile defense system South Korea will remain vulnerable. Who would call Moon Jae-in smart?
