"It would be good if America  Japan  Korea  and Mr. Kim Jong Un talk and to convince  him  to sit down on a round table and just tell  him  that nobody's threatening  him   that there will be no war  and that if  he  can just tone down or stand down  stop the threats  and that would be the same for America "  he  added.
