It’s only 80 kilometers away. The Demilitarized Zone (DMZ) is as far away as many of your car commutes, and yet in the gaiety of the Olympic Games, you forget that military on both sides of the DMZ are at the ready just in case.

And like the DMZ that separates North and South Korea, there is a social DMZ that separates those in Korea who seek reunification, and those who seek to destroy North Korea. That drama played out on Friday, February 9, 2018, hours before the commencement of the 2018 PyeongChang Olympics.

From the morning, demonstrators carrying flags of South Korea and the United States played loud music and made strident speeches, denouncing the leader of North Korea, Kim Jong-un, and very specifically requesting the United States to give a friend a hand. As the poster says:

“We, the South Koreans urge the United States to conduct an immediate preemptive strike on North Korea!”

These anti-North Korean demonstrators were dressed in heavy down jackets, and the average age was easily over fifty.

Also from the morning, about half a kilometer away, demonstrators sporting the blue-on-white reunification flag of Korea were advocating for unity and peace. These group was decidedly younger, many of them appearing to be in their twenties, most of them synchronized in matching white down coats and blue hats. Their posters were decidedly more conciliatory in tone:

White poster: We support peace (between N and S Korea), and joining under one-Korean flag. Welcome North Korean team! Congratulations on the Joint North-South entrance in opening ceremony! This is the Realization of the Peace Olympics.

Blue poster: “We enthusiastically welcome our North Korea family.

And so, a little over three hours before the 8 pm start of the opening ceremonies, the two sides were drawn irresistibly together. As I turned to leave the anti-North Korean protests, which featured impassioned ripping apart of images of Kim Jong-un, I noticed up the path I was walking the blue hats of the pro-unification supporters. I did a 180, wondering what would happen….the scene from West Side Story as the Jets and the Sharks approach each other for their rumble, coming to mind.

When the blue hats reached the rotary, the younger members in their white coats gathered in the middle rotary….and did what they do best. Sing and dance. The rumble was on.

Thankfully, this was a peaceful rumble. People on both sides stayed on their own side. The Opening Ceremony started on time without controversy, and athletes from both South and North Korea entered into a raucous stadium together, waving the blue-on-white.

On the whole, surveys indicate that slightly more South Koreans are against the unified team, than for it. The emotions run deep.

But for one night, there was unity.
