2. Secretary of State Mike Pompeo headed to North Korea today, facing a steep challenge: ironing out a clear schedule for the denuclearization of the Korean Peninsula.

President Trump has celebrated his meeting with North Korea’s leader last month, but Kim Jong-un retains all of his nuclear abilities, and thus his leverage. Above, Mr. Pompeo after the U.S.-North Korea meeting.

And the Iran deal looms over the talks. Mr. Pompeo must exceed the terms of that agreement, which Mr. Trump dismissed as a “disaster” before pulling out of it two months ago.
