Buzz about the 2018 Winter Olympics has spanned from normal fare like medal contenders and historic firsts, to South Korea's detente with North Korea and the fallout from Russia's doping scandal.
The two Koreas held top-level talks for the first time in years last month, when North Korea announced it would send a delegation to the Olympics. In order to avoid escalating tensions with North Korea, the U.S. agreed to South Korea's request to delay joint military exercises until after the Games. North Korea has responded to past drills by test-firing missiles.
Meanwhile, after the International Olympic Committee banned Russian athletes from competing under the national flag for systemic doping, the International Court of Arbitration for Sport overturned doping bans on 28 Russian athletes and reinstated seven gold medals the Russians won in the 2014 Sochi Games.
