Obama: North Korea must stop threats

In a joint press conference with South Korean president Park Geun-hye on Tuesday, President Barack Obama said that North Korea must stop its threats and take meaningful steps towards denuclearization to end its isolation.

"If Pyongyang thought its recent threats would drive a wedge between South Korea and the United States or somehow garner the North international respect, today is further evidence that North Korea has failed again," Obama said.

North Korea has issued a series of threats over the past few months. Its threats involved warning of a nuclear attack on U.S. soil and all out war on their neighbor, South Korea, continuing a trend which has been seen in the past.

The United States and the Republic of Korea have been allies, maintain military cooperation and securing the demilitarized zone.

"Our two nations are prepared to engage with North Korea diplomatically and over time build trust," Obama said. "But, as always, and as President Park has made clear, the burden is on Pyongyang to take meaningful steps to abide by its commitments and obligations, particularly the denuclearization of the Korean Peninsula."

The recent threats have gone silent in the past weeks. North Korea has moved missiles away from launch positions, but tensions are still high.

"And I want to make clear the United States is fully prepared and capable of defending ourselves and our allies with the full range of capabilities available, including the deterrence provided by our conventional and nuclear forces," Obama said.
