North Korea is raising an aggressive voice following President Trump’s early withdrawal from talks with its leader Kim Jong Un in Vietnam on Thursday. But there are three reasons not to worry.

Foreign minister Ri Yong Ho lamented that the U.S. had rejected Kim Jong Un’s demand for in-tandem sanctions relief in return for staggered denuclearization actions. This in-tandem demand, the foreign minister said, “will never be changed.” The minister also suggested that the U.S. doesn’t understand North Korea’s red-lines for any deal.
