Mr. Trump said he planned to meet the detainees, all U.S. citizens of Korean descent, seen above on a news broadcast, when they land in the U.S. at 2 a.m. Eastern. He also announced that the time and location had been set for the summit meeting with Mr. Kim, giving only one detail: It will not be at the DMZ.

But a new question is dogging the planning: Will Mr. Trump’s decision to pull out of the Iran nuclear deal send the wrong message to North Korea?
