Council on Foreign Relations President Richard Haass — author of "A World in Disarray" — provides his takeaways on President Trump's failed Hanoi summit with North Korean leader Kim Jong-un, which ended abruptly with no joint statement or communiqué.
Haass' bottom line: "Sometimes you have to walk," President Trump said, and he is right. This was one of those times. No deal was better than a bad deal. What's more, walking might well strengthen Trump's hand with N.K. down the road and with China now, as the trade talks reach a critical juncture.
