The participation of US athletes in the 2018 Olympic Games in South Korea's Pyeongchang is still an "open question" against the backdrop of the North Korea-related tensions in the region, Ambassador to the UN Nikki Haley said.
"I think those are conversations that we're going to have to have", she added.
"What have we always said - we don't ever fear anything". And certainly, that's a flawless opportunity for all of them to go and do something they've worked so hard for.
"What we will do is, we will make sure that we're taking every precaution possible to make sure that they're safe and to know everything that's going on around them", Haley said.
In September, France indicated that it would not compete in the 2018 Winter Olympics if safety could not be guaranteed and the state of North Korea's atomic weapons program intensified.
Trump Wants to Drastically Shrink These National Monuments
The tribes point to a federal lands law from the 1970s that says only Congress can actually reduce or nullify a national monument. The President's move was met with protests in Utah and in San Francisco by environmentalists and some Native Americans.
Athletes around the world are in the midst of qualifying for the Winter Games, and despite Haley's remarks, Mark Jones, a USOC spokesman, said the American contingent is not having second thoughts about participating. "We have to watch this closely, and it is changing by the day".
The U.S. this week has run military drills with South Korea by flying dozens of planes in a show of force.
"The goal is to do so", she said.
"We haven't heard anyone saying they aren't coming", said Nancy Park, spokesperson for the Pyeongchang Organizing Committee.
Haley said Wednesday that while the situation in the region has grown increasingly grave, the US has been able to rally the "entire global community", including China and Russian Federation, to put pressure on the Kim regime. "As a result, we are in close contact with numerous security agencies, including the U.S. State Department, which continues to advise us that it is safe for Americans to travel to South Korea".
