It's well known how much North Korea and South Korea oppose one another. Of course it all dates back to when Korea gained their freedom back in the 20th century. At that time, the peninsula was split in half with the North backed by Russia and the South backed by the United States.
Since then, the North has been ruled as a dictatorship, while the South has similar freedoms that people in America have.
Conditions are so bad in the North that often times people will flee to the South. That's of course if they're not caught and tortured or killed on the spot.
With South Korea set to host the winter Olympics in Pyeongchang next month, the North and South have informed the International Olympic Committee that they would like to come together and field a joint women's hockey team instead of having separate North and South Korean teams, according to CBC.
This is monumental given the fact that both countries are separated by the most heavily guarded border in the world, that includes fences with razor wire and miles and miles of land mines in order to keep people from leaving the North.
Now this isn't the first time that both the North and the South have sent joint teams to a major event, but it would be a first for the Olympics. They previously had joint teams in 1991 for the World Table Tennis Championships in Chiba, Japan, and the soccer World Youth Championship in Portugal.
That means it's been 27 years since both countries have come together to unite for a sporting event. That's an entire generation.
In the past, things were so bad between both countries that the North ended up boycotting both the 1986 Asian Games and the 1988 Olympics, which were held in Seoul, South Korea.
South Korean president Moon Jae-in is hoping to unite both of the countries through the Olympics, in hopes of cooling down all the heat that Kim Jung Un and the North have been spewing with their ongoing nuclear weapons tests that has sparked a war of words with United States president Donald Trump.
Moon also hopes to coordinate a joint march between both the North and South, which would be a good thing for both countries.
