Proponents of the "freeze for freeze" nuclear scheme say it's the best way to benefit from current positive sentiment

The Olympics can help resolve North Korea's nuclear impasse, but Seoul and Washington will need to play their cards carefully, experts said

Next month could see North and South Korean athletes marching together at the Olympics for the first time in over a decade — following a year of escalating hostilities over Pyongyang's nuclear and missile program. But once the Games are done, many fear North Korean dictator Kim Jong Un will resume his belligerence. That's where sports diplomacy can help; officials are expected to capitalize on the Olympics to try to carry forward denuclearization talks. Kim's decision to send a delegation to the Winter Olympics in the South Korean city of Pyeongchang "could be the beginning of an overall diplomatic dialogue," said John Park, adjunct lecturer at Harvard Kennedy School. "There's hope that as more dialogue channels open up, there can be a focus on security issues." For now, discussions between Seoul and Pyongyang — the neighbors held talks for the first time in two years on Tuesday — are focused on North Korea's participation at the Olympics and reducing antagonism until the Winter Paralympics in March.

'Freeze for freeze'

The forthcoming Winter Games will be North Korea's first since 2010. Aside from boycotting the 1984 Games in Los Angeles and the 1988 Games in Seoul, the pariah state has participated in all Summer Games since 1972. "The question is really whether or not it is possible to build momentum through the process of North Korea participation in the Olympics that could lead to sustained tension reduction," said Scott Snyder, senior fellow for Korea studies at the Council of Foreign Relations. "That probably will involve negotiations with the United States."

Proponents of the "freeze for freeze" solution say it's the best way to benefit from the evolving winter thaw. The strategy involves pausing annual US-South Korea military exercises, as long as the North refrains from further nuclear and missile tests. The administrations of President Donald Trump and South Korean President Moon Jae-In recently announced the drills will be delayed until after the Olympics. "My hope is that this current diplomatic opening will result in a de facto freeze-for-freeze," which should last until the Olympics are done, said Tom Collina, policy director at Ploughshares Fund, an anti-nuclear weapons group. "The goal now is to get the U.S. involved in talks so there is enough dialogue for the dual freeze to be extended for as long as productive talks continue." The White House has previously rejected the idea of a double freeze, however. Meanwhile, China, a country that also wants to see an end to U.S.-South Korean drills, is watching developments closely. "From a Chinese perspective, what is happening right now between the two Koreas is viewed as the beginning stages of the freeze-for-freeze diplomatic approach," said Park.

A short-lived truce?

Many believe the Olympics will produce short-lived peace and one-off gains, such as family reunions, since fundamentals of the nuclear deadlock remain unchanged. Kim wants the world to recognize his country as a nuclear state before denuclearization negotiations can take place, but the White House has said it won't acquiesce to that demand.
