The AP reports that the Trump/Kim summit in Hanoi has broken up early because of a failure to reach a deal.

Trump, in a news conference after the summit abruptly shut down early, blamed the breakdown on North Korea’s insistence that all punishing sanctions that the U.S. has imposed on Pyongyang be lifted without the country committing to eliminate its nuclear arsenal.

“Sometimes you have to walk,” Trump explained, adding that he had a proposed agreement that was “ready to be signed.”

“I’d much rather do it right than do it fast,” the president said. “We’re in position to do something very special.”

Part of the art of the deal is the ability to patiently get up from the table and walk away until the other side is able to give you what you need. Trump, like Reagan with Gorbachev in 1987, seems willing to use that negotiating option. I wish him luck.

The AP couldn’t resist inserting this into the middle of their story—

The breakdown denied Trump a much-needed victory amid growing domestic turmoil back home, including congressional testimony this week by his former personal lawyer Michael Cohen, who called Trump a “racist” and “conman” and claimed prior knowledge of foreign powers’ efforts to help Trump win in 2016.

If the imagined fallout for Cohen’s testimony was part of the calculus for either side in the negotiation, Trump’s apparent non-concern for it should work to his advantage by demonstrating a resolve not to let domestic U.S. issues adversely affect a nuclear deal.
