North Korea says ready to sink US aircraft carrier

The U.S. ambassador to the United Nations warned North Korea on Monday that Americans 'don't want war, so don't start one.'
Nikki Haley said on ABC's 'Good Morning America' that the when the communist country's government seized an American teacher on Friday, it risked sparking an all-out military conflict.
Kim Sang Duk, also known as Tony Kim, was teaching at Pyongyang University of Science and Technology. He was detained as he prepared to board a plane out of the country.
'I think that North Korea has been playing games from the very beginning. What we're seeing is that Kim Jong-Un is really trying to show his strength to the people of North Korea,' Haley said.
'I think that just by detaining a prisoner is one more way he's trying to show his strength, and it's not going to work.'
Haley said on 'CBS This Morning' that the U.S. is working hand-in-glove with the Chinese government to put pressure on North Korea, and it's beginning to work.
'I think we're going to handle it properly, and I think we'll have to use China to do that,' she said.
She added on NBC's 'Today' show that 'Kim Jong-Un is starting to flex his muscles because he feels the pressure' from his Chinese ally.
Haley said on ABC, however, that the U.S. isn't interested in a Chinese proposal that would call for an end to joint U.S.-South Korea military exercises in exchange for Pyongyang's plege to stop developing its nuclear missile program.
'We're not going to do that,' she said.
