In the last month North Korea threatened to launch nuclear missiles at the United States, and to annihilate South Korea.
Over the weekend North Korea declared a state of war against South Korea, but some Koreans living in Lexington have no fear.
"I don't really worry about it, because my parents say, for fun, they say a barking dog never bites," said E.J., a native of Seoul studying at UK.
Another South Korean student says when he calls home, his parents don't even talk about the situation.
"I think it's that they don't really care. North Korea's been threatening us for many times so I'm not that worried," said Saewoong Hyun.
A South Korean Assistant Professor at UK says he's surprised the students worry so little.
"I am concerned about this situation, because of the news talking about the threat, but on the other hand, I'm also like oh it's going to be OK. It's going to be OK," said Daehyun Kim, who moved to the U.S. in 2005.
Kim's younger brother and parents still live in South Korea. He served two years as a South Korean Marine. He says he feels helpless.
"I'm afraid there's nothing I can do here, because I cannot fly to Korea once something happens," said Kim.
Youngwha Kim moved from South Korea to the United States about 20 years ago. He says the North made so many threats over the years, he now feels numb to them.
He says the threats feel more serious this time, but he's optimistic.
"I worry more, but I still and I trust that God's going to protect," said Kim, the Pastor at the Lexington Korean Presbyterian Church.
Everybody we spoke with did not believe war would break out.
