It took one statement by Trump and N. Korea is changing their rhetoric to peace. Obama didn't get the message, but China did. The last thing China wants is a nuclear Japan and S. Korea. Meanwhile, another Iranian ballistic missile fired in defiance. This one is different though. It shows Iran's willingness to strike and go to war. They weren't testing, they were practicing. Not a show of force, not a warning shot, it was a statement that they mean what they say. And when Iran's leaders say "death to America" or "wipe Israel off the map" they mean it.
