In surprising symmetry, North Korea is said to be abuzz with talk about the Nobel Peace Prize and the possibility that it could be awarded to Kim. The Kims are generally overachievers: Kim is said to have started driving at age 3, and his father had five holes-in-one in his first game of golf, not to mention a perfect score of 300 the first time he bowled.

It is, of course, delusion to think that either Trump or Kim will win the Nobel Peace Prize, and in general it’s not a good thing for leaders to go into a summit delusional. Many security officials in the United States and abroad worry that in his quest for the prize, Trump might make some rash pledge, such as to withdraw American forces from South Korea.

But delusions can be helpful if they make each side more willing to make concessions and pursue an arduous peace process. I don’t think there is any prospect of North Korea handing over its nuclear weapons soon, but it is possible to see a diplomatic path that leaves the world safer — and there’s a fighting chance that we might achieve this.
