President Obama says the United States and South Korea are determined to stand firm against North Korean threats and that the days of Pyongyang manufacturing a crisis to get international concessions "are over."
In a joint news conference with South Korean President Park Geun-hye on Tuesday, Obama said the two leaders "very much share the view that we are going to maintain a strong deterrent" against North Korea.
"We're not going to reward provocative behavior, but we remain open to the prospect of North Korea taking a peaceful path," he said.
