I asked James Clapper, whose new book "Facts and Fears" is out this week, how President Trump should proceed after the pre-summit breakdown with North Korea.

The bottom line: Clapper, who was an intelligence officer in Korea in the 1980s and three decades later served as Barack Obama's presidential envoy on a high-stakes trip to Pyongyang, is deeply familiar with the challenges posed by North Korea. He told me Trump should still aim for direct talks with Kim Jong-un, but should stay quiet on the issue in the meantime.
