An Olympic gold medal for diplomacy?

Speaking of the photo below, political scientist Ian Bremmer said, "This is why we do the Olympic games." It shows Lee Eu-ju, 17, of South Korea, and Hong Un-jong, 27, of North Korea, smiling together for a selfie during the training period before the gymnastics games in Rio.

North and South Korea are technically at war, and political relations have been tense in recent months with missile launches from Pyongyang, but Olympic sports bring everyone together. Both girls competed as individual qualifiers in artistic gymnastics. They failed to win the championship in their round, but most who saw this picture agree they earned a gold medal for diplomacy.
