Most people hope it remains that a war of words and the United States is not actually preparing to launch a strike. For the 2016 Summer Olympics in Rio de Janeiro, NBC paid $1.2 billion, or 4 percent more than the previous summer games in London, but average USA prime-time competition viewership declined more than 9 percent.
The Korean government has sought to lure Chinese tourists by allowing no-visa entry for those who possess Games tickets worth 200,000 won ($183) or more.
Vice President Mike Pence, the leader of the the US delegation, was among 12 leaders invited to sit at the head table, where he was expected to sit across from Kim Yong Nam, the President of the Presidium of the Supreme People's Assembly and representative from North Korea.
And it looks like North Korea has the early lead.

The facilities and service have been pristine, however, and instead of talking about incomplete venues or if there will be enough snow, it's the ongoing political saga of North and South Korea.
Kim Yo-jong shook hands with Mr Moon at the ceremony.
The two Koreas will march in together behind the Korean Unification Flag - a blue Korean Peninsula against a white background - during the opening ceremony at PyeongChang Olympic Stadium later Friday.
He said: "I personally say it's insane to deal with the North Korea problem through peaceful talks".
But the "exceptional measures" undertaken for the Olympics "apply only to the exceptional situation and the limited time" of the Games, he said. The Pyeongchang Olympics organizing committee doesn't disclose how many tickets have been allocated to China's authorized ticket reseller. Very very important persons are typically heads of state, and the idea is to avoid unexpected encounters. "They probably worked that out so there's no intersection at arrivals".
Also likely important: making sure Mr. Pence and Ms. Kim are seated such that "they're not in the same camera frame", he said. Under terms set by the International Olympic Committee (IOC), each Korea will have one flagbearer during the parade. I would be surprised if they did not have all the latest developments in the hopper.
