Russia will not be participating in the 2018 Olympic Games. North Korea will. This sets the stage for an event that will be dominated by political issues as much as ski jumping.
Why it matters: The International Olympic Committee (IOC) claims the Games are meant to contribute to "a peaceful and better world" through non-violent competition. But this year, South Korea is using the Games to ease tensions in the region, the latest example of how countries see the Olympics as a way to advance their political agendas.
