Two-time Olympic Alpine ski champion and five-time world champion Ted Ligety expects cooler heads to prevail in US-North Korea tensions and February's Pyeongchang Winter Olympics to be staged as planned.

The 33-year-old American, speaking on Tuesday in his hometown at a preview event for the 2018 Winter Games, said the risk to South Korea and other nations in a conflict between North Korean and American forces was simply too great to let it happen.

"There have been North Korean tensions for decades. It has been talked about as a security issue for years and years," Ligety said.

"If something happened, it would be a lot worse than me not getting to go to the Olympics. We're talking about millions of people dying."

Ligety is confident enough that he is planning for wife Mia and three-month-old son Jax to be with him in South Korea.

"I don't see it as an issue because the consequences of something happening are pretty scary way beyond the Olympics," Ligety said.

"I don't think either side would like to see it get that far so I don't think it will happen."

The Pyeongchang Winter Olympics run from February 9-25 in South Korea but will be staged only 80km (50 miles) from a heavily guarded border with North Korea.

US President Donald Trump and North Korean leader Kim Jong Un have exchanged insults amid raised tensions in recent days.

But Pyeongchang organising committee spokesman Kim Jaeyoul sees the Olympics as having a special ability to overcome differences between countries.

"Sport has a unique power," he said. "Sport transcends politics and political differences."

US Olympic Committee chief executive Scott Blackmun says he is confident based on talks with US government officials that the Games will be safe and secure.

"Should the unthinkable happen and there's a conflict between nations, that's not an issue for the US Olympic Committee to get involved in," he said.

For most athletes training for Pyeongchang, the political issues and risk of impact on the Olympics are simply out of their control and nothing to long be pondered.

"Not really giving much time to things that are beyond my control," said Ukraine-born Paralympic cross country ski medalist Oksana Masters. "I'm very well aware of it because I follow it, but I'm not worried at all."

US ski jumper Sarah Hendrickson cannot let herself worry about such issues with a need to concentrate upon qualifying for the Olympics.

"That's something I can't really focus on," she said. "I have to qualify for the Olympics so I focus on myself."

US men's figure skating champion Nathan Chen, an 18-year-old of Chinese heritage, says he isn't worried after being in South Korea earlier this year.

"Not really," he said. "Security there is basically the same as it was last February. I had no issues with anything. I didn't feel like there were security issues. Everything should be good."
