The Importance of a G7 Summit Between Japan and South Korea

David Daller: Japan and South Korea continue to have somewhat tense relations. He says the G7 summit is an issue for the United States, because these are two really close allies but also economic partners. The U.S. would prefer that they get along; there's a lot of potential in making this relationship functional, he says. David Dollar: Hiroshima offers a new way to address the pain of the past,. And I think it sends again a very important message about how operating in this increasingly dangerous neighborhood.
